Mailist to discuss all issues regarding the Digitech GSP-2101 Guitar FX Processor

I agree with the 60 cycle as well.  As a side note, make sure that
your instrument as well as the cables are decent cables (not so much
the midi, but the guitar).  I run all acoustic nowadays- however, I
was using a Dean Markley soundhole pickup- it was VERY NOISY!.  Then I
switched to a Seymour Duncan Woody now and it is really quiet!! There
is quite a difference in the size of the cable that each uses.  The
Duncan is a heavier gauge.  Don't rememeber if this was mentioned
already or not, but check what else is plugged into the neighboring
outlet.  At church, our pastor runs through an old Fender Twin Reverb.
When I run through the same outlet or powerstrip- I am noisy as heck.
 When I plug in across the way, it is quite a bit cleaner.
Anyhow- that is my experience.
