Hey gents. So as the title may or may not suggest, I have a Vox AD15VT with a problem: it will switch amp settings randomly. It is the weirdest thing. Sometimes I can play it for 30 minutes with no problem, but some times it will switch amps every 20 seconds. It's incredibly inconsistent, and it literally changes between any of the about 10 settings at random. Anyone have any suggestions? Should I switch out the little tube? Should I try replacing a cap? Should I do a third thing?
It also might help to point out that I got it 5 years used from a friend of mine, and she used it probably twice that whole time, so it mostly just sat around and collected dust for a while. I tried to clean off the inside a little bit, but this did nothing (didn't think it would, but it's worth a shot).
IIRC That's an issue these things had, and bar maybe cleaning the pot, theres not much you can do to fix it :/
