issue with my USA CUSTOM :(

So after thinking my amp had an issue, it seems its the guitar.

When the vol is off on the guitar and the amp is cranked I can still hear the guitar a little bit.

the guitar has a killswitch installed, which is wired to the jack.. and I have a feeling that its letting signal through. Is this possible ?

anyone got any ideas as to what it might be. I dont want to take it back to where i took it to get installed, because its been a while now and I never really cranked that guitar up before, until now, so i never noticed the issue.

Im sick of guitar repairers who have years of experience and work from a shop thats been around for 20 years and they still cant get **** right..

really annoyed...

Take a look at the switch wiring, and see if it's similar to this:

Hey Freak--when you get a chance to look under the hood, could you take a picture of the switch and lugs? I'd like to see if the "tech" used a SPST, SPDT, or DPDT switch.

Re: issue with my USA CUSTOM :(

First impression is that you've got some pretty ugly solder points all over the place. Try desoldering all connections, clean all residual solder with desoldering wick or a pump, then resolder everything back--cleanly.

Re: issue with my USA CUSTOM :(

I never did the solder, it was the tech... and this is a well known guitar place...

man im pissed off...

I need to get my soldering skills in check, and have never used a desoldering wick or pump.. will have to buy one..

So you reckon its just the solder thats causing the signal leak ?

It's certainly the easiest and cheapest way to start the troubleshooting. Desoldering wick is a copper braid that absorbs the melted solder as you go.

Re: issue with my USA CUSTOM :(

I must say, before he goes all crazy, every" killswitch" I've installed, especially on my 51540s, "bleeds through". My electrical work isn't sloppy either. Its not much, but it sounds trebly, and like the volume knob is on .5/10, is that similar to your experience? If it is, don't shoot the messenger, shoot the switch.

That said, hope you didn't pay too much for that" make it work" soldering job.

Re: issue with my USA CUSTOM :(

Here's a thought: the killswitch is just in the hot output from the volume pot. Is it possible that the volume pot is bleeding through some signal through the ground loop?

Soldering doesn't have to be pretty, it just has to work.

Yes TAR thats very possible, and that soldering job looks like crap. Plus those mini pots are garbage. Gut it and start over. And don't use a "tech", use a luthier.

Re: issue with my USA CUSTOM :(

so that killswitch must be a normally closed momentary switch. get a normally open momentary switch and wire it up as per Alaskas diagram. solder 2 wires to the input jack to the killswitch, then its in its own loop to the jack. thats how mine are wired up and there is no bleed through.

Exactly! Of course, Musikron is correct about the pots, too--garbage!
