Thank you all for your responses. @badpenguin Good idea. I have to try that. @daddymack I'm using a 15W solid state amp for practice. Yes, I do have another amp to use; good idea. I also have a VOM, but really don't want to take the pot plate off to test this. Its going to have to be repaired anyway because the output jack became loose and I had to tighten it. Its possible that this shifted the wiring position or is shorting out a component. Its my best guitar; I don't want to ruin it. J.White

@1001Gear, I have an 8 year old (actually, now that I think about it, probably 15 year old) Digitech Blues Screamer. I'll have to play around with the gain to see if that's causing the problem. Thanks.

@Daddymack, Yes, going directly into the amp. My board did not seem to make a difference, even though I do have an 8 year old Digitech Blues Screamer on the board.

50 year old Gibson SG Custom, so inactive pickups, and original equipment (don't know that type).

Hi, I haven't use the forum for several years, but at least its still here. Ran into a problem with my main ax: I'll pick the high E, hear the tone for a second, and then the volume drops preciptously. If I do the same with the adjacent B string, no such volume drop occurs. Has anyone experienced this type of problem before? J.White
