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

The most likely and less obvious reason for the hum is
a difference in grounding between the outlets you have
your processor, peddle, and amp pluged into.  If you
have one device plugged into an outlet on another wall
or circuit, the difference in ground WILL call a nasty
60Hz hum.
