winger Posted January 28, 2008 Report Share Posted January 28, 2008 I just noticed the tone pots in my LP copy started adding gain to my guitar's signal. Narrowed it down to the guitar causing it. Also noticed a large presence peak in my tone. I always have my volume and tone knobs on 10. I always had a nice open tone on both pickups. Since this morning my bridge pickup has an enormous resonance (presence) peak. Sounds similar to a "half cocked" wah or an oscillation. Tones out of my rig are now very shrill during the initial attack and decay very rapidly Never heard this before in the 10+ years I play this particular guitar. Are the pots / caps dying on me? Or would a broken solder joint be more likely ? Any advice? Thanks everyone. Quote Link to comment Share on other sites More sharing options...

If I could ever get tone pots in any guitar to start adding gain after 10+ years I would get a patent on it and make tons of money hand over fist. Personally, You have probably changed something - like an amp, or a cable, or a new stompbox, or installed new pickups... Quote Link to comment Share on other sites More sharing options...

But eh... you wouldn't be interested in a one of a kind, gain adding, pot, would you ? Quote Link to comment Share on other sites More sharing options...
pauseflash Posted January 29, 2008 Report Share Posted January 29, 2008 Check the pot itself. Tone pots dont "Turn Up" parts of signals as people think, they are either High or Low Pass filters depending on the cap used, that bleed signal to ground itself. If you hear the same instrument for 10 years, and then go with no tone pots, you would notice a gain increase. Thus certain players, EVH for example, exluding a tone pot from their guitars. A Tone pot is a tone sucker, no matter how you cut it. So yes the cap or pot could be blown. If the cap was shorted it would give the described problem to you. Get a Multimeter and OHM it out. If it reads .000 it's shorted. Does it adjust tone at all when you adjust, or just volume/gain? But no, you dont need meds, this is an issue that can and does happen.

winger Posted January 29, 2008 Author Report Share Posted January 29, 2008 Aah, thanks for that advice. I was affraid to have gone crazy. I'll make some measurements to check things out. While I'm in there I'll also have a good look around the solder points. Once again, thanks !! Quote Link to comment Share on other sites More sharing options...
