I like using springs instead of foam.

Can anyone help me with some troubleshooting, i've made this as an onboard for my Pbass, following the diagrams its all correct, i've put the P pickup wire directly into the pull pot where it would feed from the blend pot. Im just getting a really quiet kinda distorted farty sound through the bass now, any ideas what might be the issue, could it be the caps?

look up the dan armstrong strat mod - you can generate the N+M in series and B+M in series using a blender pot as well as parallel out of phase N+M and B+M - the best part being you can reuse the tone pot and you can have some variability rather than all or nothing (as when you have a switch) th-cam.com/video/lWF1L7GBYfU/w-d-xo.html

Great video. I wan't to ask, do you think its possible to apply this to one of the Sire preamps thats are available to buy? Would be cool to try and put one in a pedal type enclosure.

Great training video, I'll put 1/10th that amount of work into mine!

I really like the option of getting maximum top end out of basses & guitars (you can always take it away later) and find less pot load make a noticable differece. A favortie mod I do for Les Pauls is split coils, flip one magnet & wire that PUP out-of-phase, single tone control and a bass cut tone, plus what we call "Blast Thru" from a pull switch on one of the tone controls, which gets rid of everything except the PUPs and selector switch. The Blast Thrut adds a sublte high top end that can be really nice with cleaner tone and gentle chord pick raking or funky stuff. I have a 74 Fender P bass that I installed an additional bridge P pickup into about 45 years ago. . . so it has 2 x orignal era P-Pickups. In a perfect world my P-Bass would be: - No load volume pots on both PUPs for max top end (Love this idea). - Switch to make PUPs go in Series (pull on Neck Volume) which is an amazing sound IMO (I have done this to every passive J Bass I own). - Tone hi-cut (normal) and also a low-cut (bass dump). .hopefully when you pull the tone pot switch it becomes a Bass Dump control. . . . all be done without more than the 3 controls (like a J). Can it be done? This is going to make my head hurt. Am I crazy?

Terrific work as usual. Would love to see how this one ended up. Thanks again for sharing your invaluable knowledge on all things guitar :-)

My off/on button is idk like loose and idk how to fix it

Nice job. But do you know how much a set of nut slot files are? It’s far cheaper to get a luthier to make a nut

Excellent video! Short, straight to the point but still you can learn few tricks. We need more of those kind of, not useless talking and sh...!

Is it possible to have two S-1 Push switches, one to turn on the neck pickup and the other to get the guitar into series for any of the pickups

If i have a photo of a design can this be used somehow ?

Why did you use a knob from a toaster?

Wanted to thank you, I saw this a coupe years ago and saved it. This past year, I sold a 2014 Dave Murray signature strat that was like new. When I opened the case to clean it I voticed a tiny chip. I was pissed and ready to let the buyer know but I thought, screw it I'm trying this. I had already purchased the 480 and had it on hand. I tried it, and Success! No way to tell the difference. It polished up nicely. Thanks!!!!

If only it wasn't impossible to find gold J and P bass pickup covers. Been looking for months, at this point don't care if it's plastic or metal or I'll just paint the damn ones I have lol

6:34 pickup soup! Yum my favorite!😋

Seeing the puddy for a 3rd hand is worth the price of admission, alone. Ingenius

Me likee! EDIT: shopping list - soldering iron, rainbow ribbon cable, rotary switch thingy and maybe even a toggle switch instead. I was looking for a summer project so this and the Squier will do nicely.

when the volume is low on 1 side check if there is litle iron peaces/dirt on the speaker at ear side of the litle speaker ...i had this and only litle volume came out ,now fixed.

That plastic is known as Polyphenylene Sulfide (PPS) and is known for its characteristic metallic sound when clanged.

Rob great channel, what sort of usb scope do you use. Thanks

Do the 2 and 4 positions still noise-cancel when switched to series?

Damn, I liked the beak

@robmods How would you wire a JB with the coils in series and still retain hum-canceling properties of the counterwound & opposite-polarity pair of pickups? Series coils boosts low-end so well, sounds much better to me. But I want to still be able to change the blend between neck and bridge pickups and vary overall volume - while retaining the best hum cancellation I can.

Thanks 🙏

I bought a body and neck of a Vintage (brandname) V4 jazz 2007 Sunburst finish. It'd been hacked with a router to make room for pbass pups so in need of wood repair, which after watching your shows Rob I feel confident in doing now, thanks. As I was tyding bits up I noticed a bit of peeling lacquer, so my adhd kicked off and i started peeling, it all came off. Total crap! So now its all natural but with a under varnish type coating. Just show how an instrument that cost about 300 quid in 2007 has a poor finish, wonder if others peel like an orange too. Going to follow your methods, spray it a nice vintage looking cream and see how it looks. Making the pickguard too from a A4 sheet of black acrylic as its missing. That was interesting working out the dimentions from old adverts. Anyways Rob, great show as usual. Keep it up mate. Looking forward to a new one 👍

Active bass battery woes 1) the battery has leaked and corroded the circuit after I left it in for a long time 2) the battery drained when bass was left plugged in amp with power on too long and 3) to solve this problem, I installed a removable battery case . Putting the battery in and out of the case led to the contact wires to the removable case breaking. Bass hasn’t been used for months now 😢

And put a tap tempo button? How i do this?

Rob, blink twice if this is Tom Misch’s guitar 😉 cool video

Thanks for the video. I have 70s jazz basses with this preamp and all sounds good awesome! 🙏

What a great video, thank you! The Blu-Tack "soldering stand" is an idea I will definitely adopt. I see that you put the resonance-taming resistors in series with the caps. I have seen schematics where resistors are placed in parallel. Not sure I understand the difference between those two approaches, could you elaborate?

I need brown colour for head corner its not only paint but damage too😞

Great Job with this. Enjoyed it.

Thats a SICK looking tele I love the zebra in the neck position and a wonderful repair

Any repair experience with, or advice on; with a skunk stripe where the stripe is slightly sunk and slightly raised in sections of the neck?

Do you have 3 band?

Hey, thanks for the video. I recently got Ibanez RB 851 from similar era and with exact same pickup design and exact same problem. In my case both pickups have one coil inactive which I find very odd. I will definitely attempt to de-pot them and rewind if necessary. I am hoping mine will be as compliant as yours :D

For those P-basses that have 13 holes, there are aftermarket gold anodized pickguards. Seen a few on Amazon.

Thanks for this - I managed to get the action down from something you could comfortably fly a 747 under to just a few mm.

I recently got a 1980 Aria Pro II SB700 and it's noisy as hell (60 cycle hum). The MB-1 humbucker isn't humbucking...

HOW TO STOP THE HISSING SOUND ONY JBL NC 760 ?

Thank you so much, this made me understand better what's happening with my pickups ground noise. I just added a Kent Armstrong lipstick bridge pickup to my bass that already had a neck humbucker pickup with only two leads, hot and ground). I added a rotating 3 positions selector too. As soon as I plugged it in, the Humbucker started to make that ground noise when selected. The lipstick is ok when selected. Should I try to reverse the connection of the humbucker?

wich Capacitors dif you used with wich resistors ? Thank you ..

Hello, I have a problem with the design, I have a jazz bass and when I turn up the bass I feel the sound that saturates, what could it be?

@Rob Mods enjoy the Wurlitzer electrostatic continuous free reed organ vibrato circuit. The North Suburban Hammond Organ Society did some really good animated tech articles. VIBRATO CIRCUIT EXPLAINED-- first a little info about Hammond tone wheel organ vibrato and simple theory- nshos *DOT* com/HAMMOND8.htm And here is the unique Wurlitzer purely electronic vibrato ( nothing mechanical) nshos *DOT* com/WUR12.htm The Wurlitzer continuous free reed organ was Wurlitzers answer to Hammond's instant attack. Putting all of the reeds in motion at once from the moment the organ was turned on allowed for this instant attack. It required all of the reeds be soundproofed. This Wurlitzer 4600 (in tech article link above) 25 pedal 2 x 61 keys ( and 4410 spinet version) organ introduced in 1954 was also the first ever organ with sustain. Wurlitzer invented the clever bleeder cap + resistor on each and every key for sustain decay on the DC Keyed keyboards ( a common method of all manufactures...except Hammond, the Hammond tone wheel organs aka B3/C3/M3 etc. were never conducive to sustain)

Steam!

I feel like a video like this is needed for people who don’t know anything about changing pickups. But like most pickup changing tutorials, it seems to be made under the assumption that everyone watching already knows how to change a pickup. I didn’t get any explanation or instruction that I needed really

Great Video Rob! Any replacement for 2n5484? I can't get it here. Awesome content!!!!

Thank you for such an interesting and informative demo! I just started working on bass guitars, (previously, I’ve done repairs, modifications, design and building electric guitars for about 44 years). Do you also shield inside the control cavity? Is there a reason why you don’t wax pot the pickup? I just bought a pot (for melting shellac as well as wax). I also an architectural and structural designer for a career but do woodworking design (CAD) and building. I also do hand dovetailing/mortise and tenon joints. Thanks again!

Gotta love that 70s Jazz pickup position. So much more bite. You have to shield them pretty good or they're a can of bees haha.
