My discrepancy with the Supa-Puss was that I couldn't really find a way to have the repeats be at the volume I desired without sending it into self-oscillation. The "Gain" knob is definitely a cool feature, but I found even the slightest adjustment away from all the way anti-clockwise had a really big affect on how quickly it would jump into self-oscillation. When dialed back, any repeats beyond the second one were just too quiet, especially when I had other things going on top of it. To the point where it was kind of like, "What's the point of having this on if I can't even hear it?" Playing solo, it was fine. And I loved that it had tap tempo capabilities (in fact, this was the main draw to the pedal in the first place). It was just too quiet when used at "normal" delay settings. Never played on the Aqua Puss, so I can't comment on that one.
