Ordered a pedalboard and been stressing about having to spend money on an isolated power supply for my pedals. This is the video i needed to hold on to my 1-SPOT and relax. You saved a poor student from burning a hole in his wallet. Thank you for the informative video!
Love Truetone. Straight talk, not selling magic fairy dust but well-designed products. My H2O V3 is beautifully voiced, the tone control on the chorus/vibrato side is a great feature to make it play nice with any amp, the small footprint makes it an easy fit in almost any pedalboard, top-mounted jacks are a +, the switches are great and confidence-inspiring, and the power protection (from AC supplies) just shows how thoughtful they are in their design. They are truly great products at a very fair price. And here they are, telling you that you may not need to spend as much as you thought. That's class, folks.
@@kissapeles The daisy chain only has 8 plugs. And most outlets have two plugs and a onespot only takes up one plug. So if you use two you're less likely to get interference and you always have a spare.
This video was so helpful. I'm a novice pedal board builder and thought I had to start with something complicated and expensive but you sold me. Going to start with a 1 Spot and see how it goes.
The thing that I dislike is people saying that you should never daisy chain. I tend to use isolated power for digital pedals, in case they emit ground noises from internal word clocks. I believe those artefacts may be filtered out with some simple cap/resistor combination. Also, I love the Sauron reference!
Good info. Long time ( daisy ) One Spot user. Have a CS12 too, different board. The (daisy) One Spot currently powers my 'ambience' portion of my church board - TC Flashback, Neunaber Immerse II, EHX Canyon, Boss Tremolo, and a WOBO TBP 2 channel loop pedal = 0 noise, 0 glitches. I was concerned when purchasing the EHX Canyon, people said it was "picky" regarding power supply - No problem w/ this ( daisy ) One Spot. Great job guys, you've been powering me for many years. Thanks!
I love my 1-SPOT! I use it with a daisy-chain to power all my pedalboard that has 12 pedals: 2 JAM, 1 REVV, 1 Xotic SP, 1 MXR, 2 BOSS, 5 TC Electronic. Soooo quiet, great job and great video!
Thanks. You were correct. Putting the dsp effects that draw the most mA 1st in the chain has absolutely worked. I didn't need anything else. Plus those dsp effects being 1st in the chain now are working & sounding way way way better now.
@@TruetoneFX I am really glad this worked. I would like to understand better why it worked. Is there any documentation that you can share that will help me understand better why it did work? The overall load didn't change. Other than voltage drop across the length of supply wires, I think it shouldn't matter? I really want to get a better understanding of why it worked.
been using a one spot for a couple years now. over the past year I've been slowly building a new custom pedalboard and I almost convinced myself to buy an MXR Iso brick. I still may in the future but if you're like me thinking you NEED it, trust me you can save your $200 and buy a onespot. It will do the job efficiently.
I’ve always used the one spot for roughly 6-8 pedals at a time. Out of curiosity I bought the one spot pro. I honestly can’t tell that much of a difference as the one spot was always quiet for me.
It's true, I have used for many years one of these and It makes no noises. Once I had noises and I thought the problem was from the SPOT Daisy-Chain, after making some test I discovered the noise came from a cable wrapped over my amp. Affordable and very good product.
I’ve been a 1Spot user since the first gen with the smaller twin cable version. So thankful you guys upgraded to the more robust cable years ago. I used the time factor and Boss DD20 back in the day and they were noisemakers. I use my HXFX for everything now and 1Spot (with proper adapters) is an upgrade from the ridiculous stock Line6 wall wart. Thanks guys!
Thanks! You just showed the MXR Reverb which was causing major noise on my board with daisy chain power. I am returning that sucker! Now all is nice and quiet with the 1Spot.
I had a cheap chinese 9v dc power supply to run 6x digital Boss effects pedals through a daisy chain. The humming it created was loud and horrible. The power adapter stopped working so i went and bought the 1 spot 9v dc power supply rated at 1700mA. My amp is very quiet now, the hum is gone for good. 1spot 9v dc power supply is a great product!
Man!! I was stressing over power on my little pedalboard and this reminded my I had bought one of these years ago, I dug it out and presto!!! All powered super quiet. Thanks a bunch. I love the info here
The Line 6 delay DEFINITELY causes noise, even when not engaged. It clicks in time with the tap. That's why I got rid of it and went to the TC Electronic Alter Ego.
Thank you for this! I am building my first pedal board (5 pedals) and was about to drop some coin on a fancy power supply. I’ll at least try this first, I can always return it if it doesn’t work out!
I've heard from some that some digital pedals filter off the high end digital noise and dump it to ground so if you have a pedal that's sharing ground you will hear that dumped sound in the next pedal. Something similar to when you get car engine whine through your stereo when you power your device from the lighter plug. Just another thought.
So if we power say 3 digital pedals with 3 different power adapters, and then connect the pedals to each other using standard patch cables, there won't be noise? 2. Also The adapter has no ground prong (only 2 prongs and not 3), so where is the ground connection? A standard power cable has a 3rd prong which is ground right? but the adapter has only 2.
I've had my 1 spot for over a decade and it's been tremendously useful. I'm not shelling out for an isolated power supply until it's obvious I need it.. and even then I might just use dedicated PSUs where needed. also nice hair bro
The pedals that make noise are due to inadequate filtering on the power supply. Digital pedals rely on an internal clock to run the DSP chips. This clock is running at a very high frequency beyond human hearing. If the circuit is not carefully designed/filtered to prevent a phenomena called "heterodyning," (which is the combining of two high frequency signals to produce a lower frequency, usually harmonic content bleeds down into the audible range) then you get the noise you demonstrated. It is also possible to get noise with pedals that take incoming 9VDC and convert up or down to a different voltage. Same issue with lack or improper designed filter components. This is why pedals like these need their own isolated/dedicated PSU to prevent these noises/perturbations from traveling on the incoming power lines to other pedals. There are also power line filters that go between the daisy chain and the pedal to reduce the noise traveling on the incoming power lines back through to the other pedals. It is a simple common mode choke designed to bleed any high frequencies to ground, reducing the noise, but some is still passed back through the lines at a reduced dbu level. I'm just a bass player with an affinity for electronics! 😄
Newbie here! I had to ask ChatGPT: "In the world of electric guitars and audio equipment, a "Daisy-Chain" typically refers to a method of connecting multiple effects pedals or devices together in a series using a single power supply source. This is done by linking the power inputs and outputs of the pedals in a linear chain, one after the other."
1 Spot already gives you lots of mileage in terms of number of pedals that can be accommodated. Imagine the 1 Spot Pro! Some even daisy chain several pedals on 1 slot of that power brick!
Noise is generated by the reference clock oscillator for the DSP or CPU. Cheaply designed pedals lack proper filtering on audio, and V+ supply rails. Another cause is a poorly designed circuit board with an inadequate ground plane layer and sufficient grounding points.
Some pedals just don't like sharing. Dunlop pedals are an example (MX-300 reverb and Echoplex for example). You cannot daisy-chain these pedals on single power supply. Fender pedals can be finnicky too. The Dunlops require a higher output power. I just went through this yesterday. Spend the money on a good isolated power supply.
First time pedal board builder! When I bought my first pedal the girl working convinced me to get this instead of just a single power source. I'm glad cuz now that I have 5 I didn't need to upgrade my plugs;
In 30 years of playing guitar and bass, I have never once needed "isolated" power for my pedalboard, because I only use pedals with well-engineered power supply that aren't noisy. If any pedal in my chain made any noise other than the noises I want, it would be immediately pulled from my signal chain and returned to the seller. My current pedalboard has 13 pedals, all on a daisy chain, from Boss, tc electronic, Digitech, and One Control BJFe. The only pedal I've ever owned that couldn't be powered from my daisy chain was a particular germanium octave fuzz with a reverse internal polarity, but regular wiring, a Voodoo Lab Proctavia. For many germanium fuzz pedals, reverse polarity is simply the way they operate.
One Spot is the only power supply that you need. I run 6 to 8 pedals usually and One Spot is quite and powerful. I didn't think that an adapter could do so much difference, it was as if my pedals took a Red Bull and a double espresso 😀
I have issues with truetone unfortunately. There is a very annoying buzz - very likely a ground loop- coming from the pedalboard. It is the C57. I tried to change extention, change socket, change cables... using DI.. nothing helped. I doubt this unit is isolating the pedals from each others. Any suggestions? 😢
I have the 12 model one spot pro I have the 1 spot and have had several of them There very solid, I am looking at their pedals just because their other products are solid. Kind of want an open road since my whole sound is ODR1
I noticed a significant reduction in noise when switching from daisy chain to isolated - especially with any time based modulation effects, or anything digital.
Just wanted to say I run 18 pedals off 1 1spot 1 flashback x4 A dual ditto 12 Jhs 3 series And 2 electro Harmonix Soul food and big muff No noise no problems no lag no nothing but working thank you 🙏 better than a million adapters or 2 bricks
TRUETONE BOB WEIL, When analog pedals have voltage INVERTER which is converting +9vdc to -9vdc problems will happen with daisy chain power supplies because it will "short circuit" the +9vdc. Analog pedals that use circuit board POSITIVE GROUND don't mix well with circuit board Negative ground guitar pedals using a Daisy Chain power supply. Any reasons why some guitar pedals use negative center DC jacks and others use positive center DC jacks? There must be an advantage why some pedal designers use negative center DC.
My board has a pair of OneSpots, and I own a couple extras. I use them for lots of gear, not ONLY pedals. The BOSS BR RECORDER and lots of other home audio gear appreciate a solid, reliable 9VDC power supply. Great product. What I wonder is if the noisy high current pedals have some kind of power supply INTAKE design such as a DC to DC convertor, RATHER THAN A STEP DOWN AS THE VIDEO SUGGESTS, that may in fact be injecting noise outside the pedal. DC to DC convertors are typically silicon parts (smt or dip socket chips) that take a variable DC voltage in and output a stable DC voltage out. DC to DC convertors typically operate by a chopping approach, which could lead to the output noise. In RF terms, the DC Chopper is actually generating RF like a spark gap transmitter would. Alternatively the DSP chips may be creating RF in the gigahertz or 500 megahertz to 1 ghz range, and some straight lines inside the circuit board could be acting as antennas that pick up the RF waves and then a single RF pulse coming in repeatedly could set up some kind of 20-100 hz current ripple out of the pedal.
From Truetone Founder & President, Bob Weil Thanks for your detailed technical thoughts about noise generated by digital pedals on a shared power supply. We're actually in agreement on most of what you wrote. When I made the video, I was trying to simplify the information so the average viewer would understand it, without getting lost in the details. Here's what I said in the video, which lightly brushes on what you wrote: "...maybe it has nothing to do with the DSP, but it seems like it does. Then again, it could also be that because some of these pedals have a little switching power supply circuit in them, that creates a ground offset with any other pedal sharing power with it. But it’s hard to know for sure. There are lots of design details that can cause noise when dealing with digital. And the “why” of it is not the most important thing anyway.” We know that if there are two digital circuits operating at slightly different frequencies, and if those differences are in the 20Hz-20kHz audio range, noise will be heard by the user... just like 2 strings on a guitar that are slightly out of tune with each other, creating a "beat" frequency. That's not the only possible source for noise, but it is certainly worth mentioning. As I concluded in the statement above, the "why" of it is not the most important thing... and most musicians don't really care. They just want to know what pedals will work on a daisy-chain and what pedals won't. Thanks for delving deeper though... always appreciated!
@@TruetoneFX Right. And I super appreciate this video because it counters a lot of nonsense out there. I've had a fantastic time using the 1Spot and I recommend em to all my buddies. It really is a great device.
I use a 1spot, through a Marshall JCM900, running a Boss SuperChorus, a Dunlop Wah, a proco Rat2, a Boss Noise Supressor, and a Boss Tuner. It’s SO QUIET!!!!
You have the nanoPOG in the section that doesn’t make noise in a daisy chain.I have all analogue mostly earthquaker pedals and I’m getting the noise when using my Nano Pog and a 1Spot daisy chain.
I found that I am getting too much noise from my One Spot. I tried using the One Spot to power my Boss TU-3 tuner pedal. I don’t need the tuner…I’m simply using it for its internal buffer because my multi effects pedal (Line 6 Pod Go) needs one if you want more clarity. When I switch to a battery, it is better. I think the One Spot is a great product, but for some reason it doesn’t work in this situation. I have tried different locations. Any ideas? Thanks!
@@TruetoneFX I bought it around a couple of years ago. The only other thing that happened was when I was powering the same tuner and an overdrive pedal with a daisy chain . I play a boss katana amplifier, and when I changed channels with it own switcher, , I could hear the ticking of the delay effect. To rectify this, I quit daisychaining and powered my overdrive from the tuner.
I am using 1Spot daisy chain on Polyeffects Beebo, Universal Audio Starlight and Golden Reverberator. No noise and working flawlessly. I might add a Strymon Cloudburst at somepoint : )
Thanks will try one. Even I don’t understand the math behind how can one adapter with about 2A power specifications could power bunch of pedal with say 200-800ma random power draw.
I bought one! Unfortunately no daisy chain included 😂 I hope any common daisy chain cable can be used and wont be the culprit of noise otherwise it will defeat the whole purpose of my purchase 😝
I had to switch to a CS12 because to much noise ona 1 spot daisy chain after adding more and more pedals. I kept that 1spot as a spare, but it seems it died at some point, because it's really noisy now, unlike in the begining.
Thank you for picking up a CS12. As far as the 1 SPOT, it sounds like something has happened to it, or you have added a pedal with some noise issues. Please contact us support@truetone.com
Silly question but I want to hear from the source... when using the 5 connectors cable, do you need to use all 5 or can you leave few with no connection? Thanks
So, I have a one spot powering my boss WL-50 chordless, into a TC tuner to a TC compressor to a wah then into my TC nova system. It is noisy. I have to gate everything, which is very annoying. Any recommendations, please?
can i use a daisy chain with low power digital pedals like a donner yellow fall delay or DE fab chorus ? or would isolated be better in this instance ? just curious as i hear most people associate daisy chain noise with high power digital pedals
watching this because i have cs12 pro on the way... i have bigsky i think it is fine to put on 250ma because i would not be using all that current provided by cs12. bigsky, hx stomp & tc electronic tripple delay is only the hungry pedasl on my chain. all the rest is analog drives
Very good advice on having a one spot & daisy chain connector in your gig bag 🎛🔌💼 . That is a life saver. Thanks for explaining it all so succinctly. I just bought the one spot pro 12 and was searching for a video on it and your video popped up.
This might be a silly question. I’m new to the world of pedals, do I need patch cables when using the 1 spot slim adapter and the multi plug cables? Thanks for any feedback!
I have tried two OneSpots and they are both adding a considerable amount of noise even when I connect them to even a SINGLE pedal. I have tried this with all of the pedals I own individually, I have plugged the amp and power supply into various sockets around the house and I have tried DI-ing my guitar into my USB interface to make sure it is not a problem with the amp. Every time, I plug my guitar into 1 pedal and the pedal into the amp/interface and there is no noise - then as soon as I connect the OneSpot to the pedal , an audible hum is heard. Can you offer any advice? Thanks!
I had to remove mine from the pedalboard. I had the One Spot chained and powering a Digitech Drop pedal, and 2 EHX pedals: Synth9 and Mel9.. This was generating an oscillating noise.. Once I changed to individual supplies thru a power supply block, dead quiet.. I am not saying is the One Spot.. because it only happens when I chain these EHX pedals..
Hey Ernesto - Thanks for your feedback. If you like guitar synth effects, check out the Boss SY-1 Synthesizer. It has tons more sounds than the EHX pedals you mentioned, sounds amazing and works on a daisy-chain, like most Boss effects. Honestly, it's one of the most fun pedals I've ever tried! - Bob
Hi, I'm having some problems with my one spot. I currently have 7 pedals (daisy chained) which are pretty cheap ones but there is this humming and almost small beeping sound coming through my amp, I thought this would be my digital delay, I took it out of the chain and there's still noise. I have these pedals: (not in signal chain order) Flamma Modulation (11 effects), Sonicake vol/wah, Tc electronic delay, Flamma comp, cheap Vintage overdrive, rowin noise gate, and a lekato looper/tuner. Are there any recommendations to stop this noise altogether, maybe it's another pedal? I'm not sure but it is very noisy. Thanks!
What if I use two 1 SPOT adapters on my pedalboard, would that significantly increase noise? I have a DL4 and 6 additional pedals (that do not produce noise). Because of the DL4, one 1 SPOT adapter is not enough (I need more than 1700mA from one 1 SPOT). Thanks!
I’m new to pedals and I have fender Santa od and a reflecting pool pedal and a ibenze tube screamer and with the 1 spot with a daisy chain I get noise big time
The Reflecting Pool is most likely causing the noise. We recommend that you get a second 1 SPOT just for that pedal, or look at our Pro series of power supplies.
@@TruetoneFX I get the buzzing noise on my fender Santa Ana too. But only if I have it plug into my blues jr iv. But when I use my solid state amp just the reflecting pool.
@@TruetoneFX thank you for your feed back but I talked to guitar center and they think I need a power supply like the Truetone cs 7 because the two fender deal has high processor in them.
And to think that for a long time I thought the used MXR reverb I bought was faulty... I should receive my CS12 on Monday. What about daisy chaining with the CS12? In that case I guess I do have to be observant of not overdoing MA draw per output right? Thanks
Thank you for picking up a CS12. Yes, you can daisy chain, but it is best to keep to analog pedals, and yes, don't go horribly above the mA output of the dc jack on the CS12.
Ordered a pedalboard and been stressing about having to spend money on an isolated power supply for my pedals. This is the video i needed to hold on to my 1-SPOT and relax. You saved a poor student from burning a hole in his wallet. Thank you for the informative video!
How many pedals do you hook up to your one spot?

One Spot is the only power supply that you need. I run 6 to 8 pedals usually and One Spot is quite and powerful. I didn't think that an adapter could do so much difference, it was as if my pedals took a Red Bull and a double espresso 😀
Thanks for sharing!
1spot works great with my pedals...
EHX hot tubes → MXR micro flanger → DBA micro dream → EQD ghost echo
Great explanation, thanks! Learned some very useful information!
Glad it was helpful!
Such a useful video. Thanks!
You're welcome!
Awesome, I can hold of on getting the 1 SPOT Pro since I mostly use analog pedals right now. My current power supply is extremely noisy!
Maybe you could take your rig to a shop that has 1 SPOT Pro's, and see if your rig is quieter with Truetone....
0:25 paramore?
I have issues with truetone unfortunately. There is a very annoying buzz - very likely a ground loop- coming from the pedalboard. It is the C57. I tried to change extention, change socket, change cables... using DI.. nothing helped. I doubt this unit is isolating the pedals from each others. Any suggestions? 😢
We need to know about your full rig. email us support@truetone.com or call 931-487-9001
Well that explains why my latest purchase of a Digitech drop causes extra noise to the chain haha. Thanks Bob!
You might need to go to an isolated supply, like our Pro series, or a separate 1 SPOT for the Drop.
@@TruetoneFX Got the True tone CS7 and made sure not to daisy chain the digidrop. Works like a charm now!
I have the 12 model one spot pro
I have the 1 spot and have had several of them
There very solid, I am looking at their pedals just because their other products are solid.
Kind of want an open road since my whole sound is ODR1
I'm about to order a pedal board and gonna just hold off and keep my 1 spot. That will save me some cash that I can just use for a new pedal or 2. 🤘🤘🤘
I noticed a significant reduction in noise when switching from daisy chain to isolated - especially with any time based modulation effects, or anything digital.
That is why we have our 1 SPOT Pro series. CS6, CS7, or CS12.
you are absolutely correct. thank you for the info
I’ve been using a 1 spot for 15 years, but that comparison to Jimmy Fallon…. It just made me start searching.
Just wanted to say I run 18 pedals off 1 1spot
1 flashback x4
A dual ditto
12 Jhs 3 series
And 2 electro Harmonix
Soul food and big muff
No noise no problems no lag no nothing but working thank you 🙏 better than a million adapters or 2 bricks
PERFECT!!!
TRUETONE BOB WEIL, When analog pedals have voltage INVERTER which is converting +9vdc to -9vdc problems will happen with daisy chain power supplies because it will "short circuit" the +9vdc. Analog pedals that use circuit board POSITIVE GROUND don't mix well with circuit board Negative ground guitar pedals using a Daisy Chain power supply. Any reasons why some guitar pedals use negative center DC jacks and others use positive center DC jacks? There must be an advantage why some pedal designers use negative center DC.
What do you with ones that you don't use? I have a few left at the end of the chain and I don't know if they can just sit there? Any tips?
They have rubber caps that are supplied with them.
My board has a pair of OneSpots, and I own a couple extras. I use them for lots of gear, not ONLY pedals. The BOSS BR RECORDER and lots of other home audio gear appreciate a solid, reliable 9VDC power supply. Great product.
What I wonder is if the noisy high current pedals have some kind of power supply INTAKE design such as a DC to DC convertor, RATHER THAN A STEP DOWN AS THE VIDEO SUGGESTS, that may in fact be injecting noise outside the pedal. DC to DC convertors are typically silicon parts (smt or dip socket chips) that take a variable DC voltage in and output a stable DC voltage out. DC to DC convertors typically operate by a chopping approach, which could lead to the output noise. In RF terms, the DC Chopper is actually generating RF like a spark gap transmitter would.
Alternatively the DSP chips may be creating RF in the gigahertz or 500 megahertz to 1 ghz range, and some straight lines inside the circuit board could be acting as antennas that pick up the RF waves and then a single RF pulse coming in repeatedly could set up some kind of 20-100 hz current ripple out of the pedal.
From Truetone Founder & President, Bob Weil
Thanks for your detailed technical thoughts about noise generated by digital pedals on a shared power supply. We're actually in agreement on most of what you wrote. When I made the video, I was trying to simplify the information so the average viewer would understand it, without getting lost in the details. Here's what I said in the video, which lightly brushes on what you wrote:
"...maybe it has nothing to do with the DSP, but it seems like it does. Then again, it could also be that because some of these pedals have a little switching power supply circuit in them, that creates a ground offset with any other pedal sharing power with it. But it’s hard to know for sure. There are lots of design details that can cause noise when dealing with digital. And the “why” of it is not the most important thing anyway.”
We know that if there are two digital circuits operating at slightly different frequencies, and if those differences are in the 20Hz-20kHz audio range, noise will be heard by the user... just like 2 strings on a guitar that are slightly out of tune with each other, creating a "beat" frequency. That's not the only possible source for noise, but it is certainly worth mentioning. As I concluded in the statement above, the "why" of it is not the most important thing... and most musicians don't really care. They just want to know what pedals will work on a daisy-chain and what pedals won't. Thanks for delving deeper though... always appreciated!
@@TruetoneFX Right. And I super appreciate this video because it counters a lot of nonsense out there. I've had a fantastic time using the 1Spot and I recommend em to all my buddies. It really is a great device.
Thank you so much, Warren!!! Bob Weil
Can I use this daisy-chain cable off of my 1 Spot Pro for it to power more pedals?
absolutely. We advise that you put analog pedals on the daisy chain.
You guys weren't at the latest world record pedalboard with Rob Scallon? It was like 319 pedals. Around 170 more than the previous record. 👍
I use a 1spot, through a Marshall JCM900, running a Boss SuperChorus, a Dunlop Wah, a proco Rat2, a Boss Noise Supressor, and a Boss Tuner. It’s SO QUIET!!!!
You have the nanoPOG in the section that doesn’t make noise in a daisy chain.I have all analogue mostly earthquaker pedals and I’m getting the noise when using my Nano Pog and a 1Spot daisy chain.
Try plugging in 1 effect at a time and seeing when the noise starts. Some EHX effects, like the Holy Grail, don't work well on a daisy chain.
Can i connect only four pedals in to the 5 multi-plug cable??
YES!
I would guess in part because TI has always made quality chips
I found that I am getting too much noise from my One Spot. I tried using the One Spot to power my Boss TU-3 tuner pedal. I don’t need the tuner…I’m simply using it for its internal buffer because my multi effects pedal (Line 6 Pod Go) needs one if you want more clarity. When I switch to a battery, it is better. I think the One Spot is a great product, but for some reason it doesn’t work in this situation. I have tried different locations. Any ideas? Thanks!
What are you using to power the Pod Go?
@@TruetoneFX I am using the power supply that it came with when I bought it from Sweetwater last July.
How old is the 1 SPOT? Has its behavior changed at all?
@@TruetoneFX I bought it around a couple of years ago. The only other thing that happened was when I was powering the same tuner and an overdrive pedal with a daisy chain . I play a boss katana amplifier, and when I changed channels with it own switcher,
, I could hear the ticking of the delay effect. To rectify this, I quit daisychaining and powered my overdrive from the tuner.
Have that same green MXR 300 reverb and thats the EXACT noise it makes with the 1 spot in a daisy chain..
Didn’t know Sam Worthington works at Truetone!!
I am using 1Spot daisy chain on Polyeffects Beebo, Universal Audio Starlight and Golden Reverberator. No noise and working flawlessly. I might add a Strymon Cloudburst at somepoint : )
Fantastic!!!! Thank you
Thanks will try one. Even I don’t understand the math behind how can one adapter with about 2A power specifications could power bunch of pedal with say 200-800ma random power draw.
I bought one! Unfortunately no daisy chain included 😂 I hope any common daisy chain cable can be used and wont be the culprit of noise otherwise it will defeat the whole purpose of my purchase 😝
Even when using the necessary adapters or inverters, is there a problem with plugging reversed polarity pedals into a daisy chain with other pedals?
There can be with certain Fuzz units.
Thats one long pedalboard. What pedalboard is it you use there?
Pedaltrain Pro
I had to switch to a CS12 because to much noise ona 1 spot daisy chain after adding more and more pedals.
I kept that 1spot as a spare, but it seems it died at some point, because it's really noisy now, unlike in the begining.
Thank you for picking up a CS12. As far as the 1 SPOT, it sounds like something has happened to it, or you have added a pedal with some noise issues. Please contact us support@truetone.com
Silly question but I want to hear from the source... when using the 5 connectors cable, do you need to use all 5 or can you leave few with no connection? Thanks
You can use 1 or all 5. Just make sure the metal ends are not touching each other, or a metal surface.
@@TruetoneFX Thanks!
Do you experience noise from pedal on 18v vs 9v (no noise or negligible)? Is it the headroom? Thanks
You must make sure the pedal can take 18v. We have not noticed a noise difference.
So, I have a one spot powering my boss WL-50 chordless, into a TC tuner to a TC compressor to a wah then into my TC nova system. It is noisy. I have to gate everything, which is very annoying. Any recommendations, please?

can i use a daisy chain with low power digital pedals like a donner yellow fall delay or DE fab chorus ? or would isolated be better in this instance ? just curious as i hear most people associate daisy chain noise with high power digital pedals
A daisy chain on digital pedals can increase noise. But this is not always the case. It depends on the pedal.
Can I power the hx stomp, with the CS7???
YES
watching this because i have cs12 pro on the way... i have bigsky i think it is fine to put on 250ma because i would not be using all that current provided by cs12. bigsky, hx stomp & tc electronic tripple delay is only the hungry pedasl on my chain. all the rest is analog drives
Yes. The 250 mA will work great. You will have plenty of power.
Excellent video.
Thank you very much!
@@TruetoneFX I run a 1Spot PRO CS12 but I still run a daisy chain off of it for some of my pedals.
Im learning!
Very good advice on having a one spot & daisy chain connector in your gig bag 🎛🔌💼 . That is a life saver. Thanks for explaining it all so succinctly. I just bought the one spot pro 12 and was searching for a video on it and your video popped up.
You bet!
Thanks for the info and the 1Spot!
Can I plug in the boss fs7 foot switch and the rc3 in my 1spot chain? Just double checking.
Thanks for your time.
Yes you can!
This might be a silly question. I’m new to the world of pedals, do I need patch cables when using the 1 spot slim adapter and the multi plug cables? Thanks for any feedback!
You need patch cables to pass audio from one pedal to the next.
@@TruetoneFX Thanks for the response! Loving the 1 spot so far!
I have tried two OneSpots and they are both adding a considerable amount of noise even when I connect them to even a SINGLE pedal. I have tried this with all of the pedals I own individually, I have plugged the amp and power supply into various sockets around the house and I have tried DI-ing my guitar into my USB interface to make sure it is not a problem with the amp. Every time, I plug my guitar into 1 pedal and the pedal into the amp/interface and there is no noise - then as soon as I connect the OneSpot to the pedal , an audible hum is heard. Can you offer any advice? Thanks!
Please call us 931-487-9001 or email support@truetone.com
I had to remove mine from the pedalboard. I had the One Spot chained and powering a Digitech Drop pedal, and 2 EHX pedals: Synth9 and Mel9.. This was generating an oscillating noise.. Once I changed to individual supplies thru a power supply block, dead quiet.. I am not saying is the One Spot.. because it only happens when I chain these EHX pedals..
Hey Ernesto - Thanks for your feedback. If you like guitar synth effects, check out the Boss SY-1 Synthesizer. It has tons more sounds than the EHX pedals you mentioned, sounds amazing and works on a daisy-chain, like most Boss effects. Honestly, it's one of the most fun pedals I've ever tried! - Bob
Bob Weil I have an sy1 it’s fun
Hi, I'm having some problems with my one spot. I currently have 7 pedals (daisy chained) which are pretty cheap ones but there is this humming and almost small beeping sound coming through my amp, I thought this would be my digital delay, I took it out of the chain and there's still noise. I have these pedals: (not in signal chain order)
Flamma Modulation (11 effects), Sonicake vol/wah, Tc electronic delay, Flamma comp, cheap Vintage overdrive, rowin noise gate, and a lekato looper/tuner.
Are there any recommendations to stop this noise altogether, maybe it's another pedal? I'm not sure but it is very noisy. Thanks!
Start with 1 pedal, and add them 1 at a time to see when the noise starts
@@TruetoneFX Hi, I found that my looper was the cause. I've powered it with a separate power supply. Cheers!
What if I use two 1 SPOT adapters on my pedalboard, would that significantly increase noise? I have a DL4 and 6 additional pedals (that do not produce noise). Because of the DL4, one 1 SPOT adapter is not enough (I need more than 1700mA from one 1 SPOT). Thanks!
A single 1 SPOT can power the DL4 plus 6 other pedals. But no, another 1 SPOT will not add noise.
I’m new to pedals and I have fender Santa od and a reflecting pool pedal and a ibenze tube screamer and with the 1 spot with a daisy chain I get noise big time
The Reflecting Pool is most likely causing the noise. We recommend that you get a second 1 SPOT just for that pedal, or look at our Pro series of power supplies.
@@TruetoneFX I get the buzzing noise on my fender Santa Ana too. But only if I have it plug into my blues jr iv. But when I use my solid state amp just the reflecting pool.
Why don't you contact our support team. support@truetone.com
@@TruetoneFX thank you for your feed back but I talked to guitar center and they think I need a power supply like the Truetone cs 7 because the two fender deal has high processor in them.
Perfect!
And to think that for a long time I thought the used MXR reverb I bought was faulty... I should receive my CS12 on Monday. What about daisy chaining with the CS12? In that case I guess I do have to be observant of not overdoing MA draw per output right? Thanks
Thank you for picking up a CS12. Yes, you can daisy chain, but it is best to keep to analog pedals, and yes, don't go horribly above the mA output of the dc jack on the CS12.
My 1 Spot works just fine thank you. Digital and anal8g pedals. Never had a problem.
