Hey, does anyone out there still have a Digitech GSP 21 effect processor?  I had one many years ago and am trying to recreate my favorite patch, "The Abyss" but don't know where to start.  It was this great swirly wall of sound...most likely some kind of mild distortion passed through a multi-tap delay.  Would anyone be so kind as to look at this patch and tell me what the parameters are set at so I can rebuild it with my current gear?
