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

I have a pretty bizarre problem with my CC pedal on my 2101 FC.  I've 
had this for several years (ever since I bought the unit used).

I have to set it up so that the 0 value is at the toe and the heel and 
the value of 127 is in the middle.  To demonstrate, a patch that would 
gradually increase in distortion has max distortion in the middle of 
the travel and no distortion at either end of pedal's physical extremes.

No matter how I try to calibrate it, this seems to be the only way it 
works.  Is this something I need to clean inside the unit?
