I want to run a bi-amp system with one amp running distortion on it's effects loop but I can't seem to find any rackmount distortions. I found the Viva Analog 360+ rackmount but there isn't any info indicating if they are for sale or not or what's going on with them. Any suggestions? I'm looking for an aggressive gritty fuzz. Between a Muff Pi and Blowtorch is where I'm going. Blowtorch being too buzzy and Pi being too fuzzy. Buzzyfuzz is the idea here.
