Re: Is it normal to have noise with gain and the volume turned down?
I have no guitars where the noise level does not decrease by some amt. when you roll the volume all the way back to zero.
I once had an issue where pots part-way on (not rolled all the way back) created more noise; it was a grounding issue. I once had the use case where turning both pickups off at the same time using switches created noise; that was also a grounding issue.
I still get amp hiss, but less than with the volume up.
