I couldn't find any answer to my question so here's a new post...
I have a 1977 musicman, and I got a kind of buzz when I turn the treble pot.
When I lightly touch the jack the buzz stops as soon I remove my finger, It buzz again...
Do you think it's a amp problem (not grounded) or the treble pot is on his last miles ?
