Okay, I got this a while ago, but haven't been able to test it until today. What a weird beast! Juan from Pedals and effects said that it's like RAT and a Metal Zone in one box. I have had both of those and this is nothing like those. There seems to be plenty of low end, and the Crunch-side works as a grindy overdrive. The Solo-side befuddles me. It's kinda muddy, heaps of low end and it sounds like it has either octave down or clean blend. It's a really cool sound! If anybody has any info I would appreciate it! I know it's designed by James Brown of Amptweaker-fame when he worked for Peavey.
