DecepticonVibez Posted 23 hours ago Posted 23 hours ago A bit of a strange one this guys. I'm hoping someone can help. I bought an Epiphone Sheraton 150th Anniversary approximately two yyears ago. I had it professionally set up and since then I haven't touched it. It has been sat in it's case for two years. A few wweks ago I decided to get it out and have a jam. When I plugged it in there was no or very little sound coming out, even though the amp was turned up fully. After checking all the obvious things like cables I couldn't work it out. I decided to take it to a guitar tech to get repaired. The guitar tech has looked at it and can't work out what the problem is either. He has checked it all over and even changed the output jack but still there is no volume coming from the guitar. He has advised me to change the harness. He has never come across this problem before. As you can imagine I'm a bit annoyed as the guitar was pretty expensive for an Epiphone and it is supposed to have top quality electronics and Gibson mini humbuckers. I have contacted Epiphone and waiting for a response. Does anyone have an idea what the problem could be? Quote
Dad3353 Posted 22 hours ago Posted 22 hours ago Hmm... This is an odd one indeed. If a guitar tech can't find the problem with the instrument on his workbench, what hope have we..? That being said, there are many potential, albeit rare, reasons for no, or little, volume. The jack socket has been eliminated, but, as we go deeper into the signal chain, we could suspect an issue with the internal wiring, a badly-soldered joint to the potentiometers, a faulty component (tone capacitor..?), dust, dirt or worse in the volume pots, duff contacts on the selector switch and, lastly but least likely, both pick-ups having broken or shorted coil windings. These guitars are not rocket surgery, but are slightly more difficult to work on, as access to the cabling etc is poor. However, any decent guitar tech should be able to at least determine the cause, with a few fairly basic tests. I'd recommend going to another technician for a second opinion; to me, the best 'guess' would be the selector switch being stuck. Hope this helps. 1 Quote
DecepticonVibez Posted 22 hours ago Author Posted 22 hours ago That what I was thinking,, that a guitar tech should be able to diagnose the problem but I think you're right about getting a second opinion. 1 Quote

Which one? Was it little or none, because there is a big difference to what the problem could be between all of those. 21 hours ago, DecepticonVibez said: The guitar tech has looked at it and can't work out what the problem is either.

Huh? Is this a professional guitar tech or someone who just called himself that? I am wondering as there is nothing complicated at all in guitar electronics (although the nature of the sheridon makes them harder to get to), so I wouldn't be very keen on listening to the recomendation of someone who couldn't work out the problem. I assume you have tried other leads and amps etc. Its obviousy difficult to get to the componants but if you get them out through the F hole, disconnect the pickup hot first, check there is something coming out of the pickups (if you can) and check that the pickups themselves aren't either shorted out or completely open circuit, then the volume pot, then the switch and trace it through to where the sound goes away, that is where your problem is. It shouldn't take long with a meter to be able to find it out. If you are not comfortable doing this, take it to someone know knows electronics who should be able to help - they don't have to be a guitar tech at all, it is basic knowledge of electronics 1 Quote
