I have a question to do with the line 6 spider 3 15 watt amp. The potentiometer for the chorus,phaser and tremolo effects was broken off causing the chorus/flange effect to always be on. It broke at the board of the potentiometer itself not the main board of the amp. So the solder contacts were unharmed I replaced the potentiometer with one of the same rating b10k as the original Now even after I soldered the new pot in that effects knob still does nothing and the effect is still on. I’ve triple checked that I have no shorts or connections to other circuits Is there any way I can fix this problem or maybe solder something in that would make the amp think the effect is turned off? This is my only amp right now and I don’t have much options to get a replacement amp and I’ve been trying to fix this problem for weeks now with no luck. And I can’t find info on what I’m doing wrong I’ve replaced potentiometers in guitars and amps many times and not had a issue
I need help... I have the same line six. I thought it was a bad fuse, but I replaced it, and the power amplifier popped. So I replaced both. the power amplifier popped again. Fuse is fine. What am I doing wrong, and what else should I be checking?
Hey dude, wanna ask a favor. I have a Spider IV 150 that's giving me issues when powering on. I just uploaded a short video to my channel the other day that's showing what it's doing. When you get a minute, do you mind taking a look at it real quick and maybe see if you have any ideas on what the issue is? Any help or insight whatsoever would be more than appreciated.
Hi DerMetzger, you might want to try a factory reset: www.google.com/search?q=line+6+reset+shortcut&oq=line+6+reset+shortcut BTW, you may want to include a playlist link in the future. I can't see your channel from my cell phone (I can only see it from my desktop).
I’m getting a buzzing sound whenever I use my master volume. Is it the knob or the board. Does anyone have any advice. I like this amp. It’s great for practice and I don’t was to lose it. Thanks for listening.
Oops, just realized the pots may be plastic and the electronics cleaner may do more damage than fixing. In this case replacing the POT would the better way to go. Check the Line6 website for parts.
My Line 6 Spider 2 15 w the whole guitar side of the amp is dead I would love to convert to karaoke using the CD MP3 import and the guitar port for microphone is there any way to keep the auxiliary cable input jack so they can be used together
Split the stereo input to monaural input. That's what i exactly did, hence why there's a pseudo xlr input in the back and working guitar input at the front.
I don't know where else to go for this because there's nothing else about it online but when I play on the "synth lead" pre setting everytime I barely hit the wrong string it makes an obnoxious ringing sound. How do I fix this.
Awesome video, hey I need your help, I have a line 6 spider IV 150 and I don't know why but it keeps buzzing, I turned it on and I can hear the buzzing and I don't know what to do 😢
can you guys help me my cd inout works but i mainly use this amp as a speaker but it would like to install an bluetooth is this posible? i dont want to remove the cd input I would like to keep it and use it as it is
It's not the amp. It's the food you've been eating since you were a child, the govt laced most foods with mind control microbots, this is just a common symptom. If you drink more alcohol it'll supress it
So I have this amp but 75 watt spider III , and was wondering if I could bypass all the effects and plug my Fractal FM3 into it and use it like a power section and Cab? Anyways I could bypass the digital preamp or just wire up my fractal into the cd part so it won't colour my sound .
Yeah, that's what I did. I still did get some residual noise when the volume was maxed out. You could reuse the speaker and cabinet and connect a new amp head. As I have replied to a previous commenter, I am providing a way to cheaply repair these poorly made guitar amps... By the time you start researching for a decent amp head, you may as well but a new kit at that point.
I have a Line6 Spider III, When the power is switched it makes a continous noise, that over powers the guitar. What could cause this noise? bad power supply maybe?
If the noise persists when the guitar is unplugged, then it's something in the circuit, including possibly the power supply. If it's silent when unplugged, it could be a lousy guitar cable. Unfortunately these aren't well made, and the cost to repair doesn't justify the value of the amp itself. Try the cd input and if it's noisy too, it's gonna be a challenging repair.
My guitar just started buzzing a few months ago. When I touch the metal it stops. When I touch the metal screws on my spider3, 75 watt combo it stops. Is this a problem with my amp or cable? I have three guitars, they all do it
Most likely your cable. If you have a multimeter you can check the continuity of the tip of the cable, then the ring (or the metal casing of the 1/4" plug). Also make sure that you are using a guitar cable and not a speaker cable. Speaker cables are noticeable because the cable is not round, but made of two cables glued side by side.
@@Sciencenme thanks, I'll try that. It's a mogambi gold instrument cable. I'm almost sure it's a environment factor. When I turn the guitar in different directions slowly I can hear the buzzing change/ get worse.
I'm not familiar with the brand, but by design, guitar cables are 'shielded' and should not be influenced by external EM radiation. Speaker cables sometimes also use 1/4" jacks as connectors, but are not shielded, and are prone to picking up rf-interference. If anything, borrow a friend's cable and see if the problem resolves. Yes there are other possibilities for your issue, but try the easier solutions first. It is possible that the wiring inside your guitar's jack is loose too.
@@cosmixmalar since I posted my first comment i bought a Dsl20 head. And also fixed the outlet, which was open ground. But still some external source is interfering with my signal. I live right next to a power transformer, a intersection with traffic lights, cameras, businesses with alarms. All kinds of BS. But fixing the outlet definitely improved the sound of the Marshall. No more hissing when not touching the metal or strings. The spider amp sounds the same. I've heard tube amps are particularly sensitive to power sources.
great vid bro , can u advise , i spilt beer on my line 6 spider jam , 4 days later i lost half of the screen then the start & rec buttons stopped working... A bloke advised me to strip it down & spray the board with a electrical cleaning spray . Is this good advise or will the damage the beer has caused be unrepairable . Any advise be appreciated .
Yup, take it completely apart, wash the membrane with soap and water, but for the circuit board either the cleaning spray or 95%+ ethanol to clean the circuit board. If it works, you saved $$$, if not, at least you tried :)
You're better off testing the transformer with a multimeter to see if it outputs any AC voltage on the secondary coil. As many others have mentioned on the internet, the quality of Spyder amplifiers are not the best. The speaker (and box) can be reused, and if you can find a working used amp head, that's the easiest answer. The cheap Line 6 circuit board is not worth the time to reverser-engineer and try to repair :( If you don't see black stuff or smell what is burnt on the circuit board, just give up. I was lucky enough that the final amp-stage still worked, so we skipped the DSP circuitry and went for gold.
Ive got an issue with allot of background noise in mine. Worked fine 2 years ago, recently plugged it in to see if it still sounds as good as i remember. And while it does the back ground noise is as loud as the distortion
I've noticed that if I raise the master volume above 60%, weird popping sounds still happen randomly from the damaged DSP circuitry. Unfortunately from what I've read, these amplifiers are poorly made and it's a question of how much time do you want to spend troubleshooting it before realizing it's more economically feasible to just buy a new one instead. :/
@@ModernCivilWar You might try re setting it to the factory default pre-sets. If you have the guitar jack in pull it out. Turn every knob to zero. Hold down the channel 1 [A] button and turn on the amp. You will get a msg Resetting to factory default. Keep the button down and in a few seconds it will say Factor Default restored. Let up on the A button and turn the amp off. You will lose your channel settings or someone else's if it a used amp. Now you can set up your own channels. It should correct any other problems also.
@@ModernCivilWar It could be the mains power ground issues so you can try different plugs. Also if it's from the pickups there is a noise gate built in but keep in mind noise gates only eliminate guitar feedback and not the mains related ground noise.
Dude, I need your help please! I was playing the line 6 spider jam with headphones, I noticed the clip light came on a few times so I stopped what I was doing and just played it without the headphones and now it sounds hollow, almost tinny if that makes sense, in the clean settings it's ok but as soon as I switch to blues or crunch it's really fuzzy sounding now and just sound way too distorted and just fuzzy, I don't know how to put it other than fuzzy and hollow sounding, any suggestions? Line 6 is zero help when I ask and I just bought this second hand so I'm pooched if this is a huge task to fix, on please help! I can leave my contact info, anything would help!
I'm not sure if this will help, but there is a software reset you can try first: www.google.com/search?q=line+6+reset+amp&oq=line+6+reset If that doesn't work, other than hand re-soldering all the joints on the circuit board, the time to determine which (proprietary) chip is malfunctioning doesn't justify the additional time spent :( I agree, it is frustrating to read all the bad reviews, only after you have bought the product and find out how frequently it malfunctions :/
@@Sciencenme you could have just replaced the guitar input Jack and checked the traces and if the did need jumping you could have used the og guitar initial input and used the line 6 spider features.
I'm going to try and fix my Line 6 III LCD IS DEAD no sound through until you turn it off then the signal degrades as the amp disapates the power. But by the sounds of it the circuit is dead. Nobody wants to even look at these. Thanks for the video.
Mine is a spyder 11 I believe . Its cutting in and out. Volume down. Sometimes completely weird. Sounds like I have tremolo on or something. Real low and tuby. Not sure what's wrong if anyone knows be great
@Vampire7805 yea I took mine in not long ago . Guy said it was fine but didn't even have a guitar to check just used a volt meter lol so I brought one and didn't work. Got a new guitar cord and that helped. I did research and my spider 11... 75 watt one of the settings in between metal and insane is supposed to be this crazy horrible sounding one so that makes sense but still. The metal setting and the crunch setting just don't seem to have the sound I remember as a teen it's hollow . Somethings missing idk what's wrong really but I'm ready to say fuck the amp
So your cd input still works? If so, and you want a solderless job, get one of these cables. www.amazon.ca/dp/B01M6CQYUK/ref=cm_sw_r_cp_apa_i_UMVvFb8YX8B17 But if the cd input doesn't work either, you probably have even bigger problems with your amp.
