Re: [Archtop] Question for the Technically Inclined/ Just a guess........
- I suspect you're right about it being the amp. Problem I have right now is that the store that did the repairs is closed and in the process of moving. It's a fair distance away, so I can't just camp out there & hope to catch somebody.
I think I was mostly looking for someone to back up my diagnosis. Going to see if I can borrow an amp of some kind & see if that narrows it down. Problem is, it sometimes doesn't happen for a few days!
Thanks, all who responded!!

At first guess I believe it to be the amplifier.It is a good chance that a circuit or cap is opening up in the amplifier circuit after it gets a bit hot. Now thisis a pure guess, I would not ignore the switches on the axe either and see if one of those is not dropping outthe signal from a pick-up. A switch could be opening up dropping one pick-up out of the picture andturning the volume up compensates for loss of volume by pumping the remaining signal.I would go to the luthier who did your switch repair and drop it in his lap if it appeared with the returnof your guitar from his/her repair? Trial and error sometimes gets pricey quick, like replacing the battery, the alternator etc.until the car stays charged. Don't spend to much time or money troubleshooting when a pro can probablyfinger the problem pretty quickly.BernieOn Wed, Feb 1, 2012 at 6:37 PM, <dbklein@...> wrote:At 07:45 PM 2/1/2012, Doc wrote:Doc, if I were you I'd go back to the techie that changed the

switches in that guitar for you. Call him up and ask what he thinks.
