JCM 900 earthing problem?

[pagemalicious]

Every time i'm at band practices, i can hear the generator through my amp, so it needs to be sorted ASAP because im recording guitar parts next week. I know it's not my guitar.

How do i fix this problem, i've never come across this before. [img]/images/graemlins/scratchhead.gif[/img]

Is it only at band practices? Rotate slowly with the guitar turned up where it's making the noise... you may find that at certain positions the noise goes away. Kinda sucks, but might help for recording if you can stand that way. ;0

yeah only a practice so far, the generator really comes through when i don't play. just a bit concerned because of recording and gigs this week.
