It took me a while, but something clicked with this pedal. I think I just had to find my settings, and to give it a regular workout at stage volume with my band. Wow, what a great sounding and fun pedal. It takes my AC-15 clone and turns it into a mini-Marshall - or so it sounds to my ears. The yellow channel pegged with the gain around 9:00 is a beautiful thing. Anyway, I'm late to the show but I get it now. Has anyone else needed a 'break-in period' to fully realize the potential of this pedal?
