Very smart concept, here we have the whole Rat evolution. But I had to return it, cause there were a few things I didn’t like. First, the volume differences among the 9 modes are abysmal, it’s annoying while being on stage. Second, switching from one mode to another makes a loud noise. Third, the “filter” knob works clockwise on some modes and counterclockwise on others, and that is a real dealbreaker for me. Also, I found myself needing more tweaking options. Anyway, felt like this is the pedal you want to fiddle with for a week, before deciding which Rat you really want. Or maybe this is meant to be a great studio tool. Unfortunately it doesn’t belong on my touring pedalboard.
