Question about Audio Players & Recorders

Open Question

Epihone guitar tube amp puts out a lot of static even when there is no puitar plugged into it and all control knobs are turned down to zero. When the guitar is played the sound cuts off intermitently. I cant seem to bring it on by anything that I do. I have tried different guitars, different cables, wiggling the input jack and changed the tubes. Any ideas? Thanks

There should be an 8 pin IC close to the input jack that will be marked 4558 or 4560. This is an Op-amp Ic that is the most likely cause of the problem. Replace that IC and report the results here.

I just bought the Vintage Club 60 and am loving it. $300..Pretty good deal huh! Plenty of bass...Have you tried the low boost and mid boost switches? they completely change the way the amp sounds. Also the stock speakers are **** so I'm dopping some Celestion Vintage 30s. Also is anyone getting some tube jingle with the VC60? I'll probably have to take it to someone...

SOURCE: Static Noise from guitar amp.

I take it you have made sure that both the cable to the distortion box from the guitar and the cable to the amp are both good. From the description you give, it sounds like there is no signal getting to the pedal. If the cable is good, then the next likely suspect would be the input jack on the fuzz box. Try wiggling it a little with the guitar cable in place to see if it is loose. Some input jacks are unbelievably cheap and flimsy. A crackling sound (static like) is almost always a bad connection. If it was the output jack, I would think that the guitar signal would come through a least a little bit, but you might want to try wiggling that one, too, if the input jack isn't the culprit.

Another possibility to check is the battery, but this doesn't seem as likely. Some effects units devour batteries, especially units that use 9V batteries. I have a multi effect pedal that kills a 9V in about an hour.

SOURCE: cable broke off in the input jack

I'm pretty sure t6hat the output jack is a sealed unit(contacts inside soldered to the surface of the circuit board. You may be able to grasp the center shaft of the plug with a thin jawed hemostat or really skinny long nosed pliers and pull it out that way. Make sure the amp is off and unplugged from the wall. If that doesn't work you will either have to get it removed at a shop or disassemble the amp to remove the circuit board and unsolder the jack and replace it or get the broken plug out of the jack once it is unsoldered. I've never had a Line6 apart yet but thats probably the type of jack they used. Thats because it has to be electronically isolated from the chassis. Hope this helps.

Fender Hot Rod Deville 212 sounds ok then LOUD HUM


On mine, the guitar input jacks get tarnished and causes all kind of interference and noise. Take a Q-Tip soaked with WD-40, run in down into the jack and brush up and down. Don't overlook the filter caps as they are a common cause of noise. You need a capacitor checker (the older tube type) to thourghly check those out.

I have a peavy classic 100 2x12 1975 has a high pitch squeal coming out of amp when powered on


If this happens only when the guitar is plugged in, most likely there are two possibilities. The first, you have some issues with the electronics in the guitar OR are using an acoustic guitar witch has an extremely sensitive pickup that provides nothing but feedback. If this is happening with the guitar unplugged, there is a mountain of possibilities.

Peavey 6505 plus buzz...even when all controls on zero and no guitar plugged in


Sounds like a bad power supply filter cap...the buzz you're hearing is the 60 cycles hum that filter caps reduce or (hopefully) eliminate altogether. It may also be related to the tubes but finding the bad one will require some work. Any friends have this same amp? If so, try swapping one tube at a time and see if you get lucky. If this amp is new take it back ASAP as it is a manufacturing defect.

Hi there
Firstly don't panic! It might be something quite simple - and it might not actually be the amp that is at fault.. Here are a few things you can try to start with to trace the problem by systematic elimination.
  1. If you are using any effects pedals unplug them and plug your guitar straight into the amp - does that solve it? Turn off any built in effects on the amp and unplug the foot pedal.
  2. Try a different guitar lead - leads are very prone to failure -especially at the solder joints in the jack plugs - but sometimes in the middle as well because they get pulled a lot in use. The tiny twisted copper wires in the core of the lead can become cracked, which will increase the electrical resistance (causing the volume to drop. As you move about the bits of broken wires may touch again (reducing resistance so the volume increases again).
  3. Check the tightness of the screw threaded rings (bezels) that hold the jack sockets on to the body of your guitar and the front panel of your amp. These can work loose over time (especially on the guitar) and cause the jack plug to only make a partial contact inside the socket with the same results as no 2 above.
  4. On both the amp and on the guitar quickly and vigorously rotate all the volume and tone control knobs backwards and forwards (up and down) fully several times - the copper contacts inside the knobs can become oxidised over time. Doing this will clean them a bit by means of the friction between the contacts. Do this with one knob then test to see if the problem has been resolved before moving on to the next knob - that way you will be able to identify which one is faulty (you may hear some crackling as you rotate it). In the same way flick your guitar pick up selector switch backwards and forwards several times. If you find this resolves the problem you might apply a VERY little squirt of switch cleaner ( a spray that you can buy from electrical component shops like Maplin) to give the knobs / switches a more permanent cleaning - but don't overdo it and allow a few hours for any surplus to evaporate before you use the amp again. HOWEVER - don't use switch cleaner if your amp is still in manufacturers warranty AND if rotating the knobs hasn't solved the problem.
  5. If none of the above has solved the problem then the amp itself might be faulty. Don't attempt electrical repairs yourself. Apart from the obvious danger of messing with electricity you may actually do more harm than good and without proper test equipment it is extremely unlikely you will be able to trace a faulty component. If the amp is still in warranty take it back to the shop (or phone/email them if you bought it online). If it is out of warranty your local music shop may know of a good repairer in the neighbourhood who won't rip you off (they may even have their own 'techie' who can do it for you).

I can turn it on and i hear the fan going...but it doesnt make any sound when i strum or anything...please help!


There are some basic things you can try before you suspect the amp. Does your guitar cord work in another amp? Is your guitar sending sound through your guitar cord? Without any thing plugged into your amp can you hear a slight hiss when you turn your controls up on your amp? Here is a link to some things you can do to troubleshoot the problem:http://www.geofex.com/ampdbug/ampdebug.htm Even though the info is for tube amps a lot of it also applies to solid state (transistor) amps like yours.If it turns out to be the amp and you don't feel comfortable working on it and have no one that you know personally to do it you are best served by taking it to a certified Marshall repairman who will have the tools, parts and schematics to help you.

Here is a link that might help:http://www.geofex.com/ampdbug/ampdebug.htm Unless you have the tools and experience to work on your gear it is always best to take it to someone who is qualified to work on that particular amp. Your local Fender dealer should be able to recommend someone.

The volume control does nothing, you cannot turn it up or down even on zero you can hear music. There is a lot of static at all times, even when playing the CD


Looks like a lot electrolytic capacitors on the electronics volume control IC may be leaky...This require change of electronic components i.e. the faulty capacitors..

FENDER CYBER TWIN AMP SOUNDS GREAT WORKS GREAT BUT WHEN YOU CRANK THE VOLUME A LITTLE LOUDER THAN NORMAL THE AMP GET STATIC OR DISTORTS OR POPS AND CRACKS. COULD THE TUBES DO THIS?


First make sure you have the TRIM knob positioned correctly. When playing loud the Red Led should just blink a bit so you know you're not overloading the preamp and Digital sections. The Twin Reverb Patch is a clean place to start so select that first. On this amp it's a good idea to set the MASTER to 5 and use the VOLUME control at as low a setting as you can. The GAIN control should be set under 4. You better sound crystal clear on this setting. Try turning up the volume to see how loud you can get without breaking up. It's a guitar amp so there will be some grainy distortion but it should be very light. I bet you get through this test without much trouble. After that you need to be very careful about what settings you're using since many of the presets may not mesh with your guitar pickups. You should concentrate on tweaking one highgain setting and learn about how the controls interact. The amp is so much more complicated than a 10 knob standard guitar amp. Most people need to put in some time to get a handle on it.

As far as the tubes go, typically they can get microphonic which was a problem with versions 1.1 and 1.0 of this amp so check that. Fender had a Cyber twin upgrade kit way back to fix this but if you have version 1.2 or 1.3 that's not it. Problems with this amp are typically caused by control setting more often than an electronic problem but this reponse should get you started figuring it out.

Amp or guitar??


I can say with a fair amount of certanty that this is the control knob on your guitar, these are fairly cheap and if you have any mechanical ability you can replace it yourself, there will be some soldering involved so if you can't do that I would take it to your local music store and most have some sort of repair department, this shouldn't be a big bill to get fixed.
