buzz

[Stiggy Darzust]

Does anybody know what i can do about the buzz that i hear when a guitar is connected to my roland vs 1680.
I tried new cables, other guitars etc. nothing seems to help

Thanx

Assuming all your guitars don't have wiring problems - Have you tried other channels on the 1680, your not sitting close to a computer monitor (if so shut it off). Is the buzz always there, or does it go away when you touch the guitar strings?
