IIn stock, ships today! The Gray Vermin is printed on "spun aluminum" with a rolling spin effect on all surfaces.
It's a 2 channel combo/stacked pedal from boutique builder Chicago Stompworks - built with highest quality parts available, neutrik jacks, true bypass 3pdt switching, true handbuilt boutique quality. 

This is two popular "cloned" circuits in one box: channel A (right side, input) in a reproduction of the classic RAT V2 LM308N distortion, channel B (left side, output) is a repro of the late 70's "gray spec" DOD OD-250 overdrive ("the Yngwie favorite"). Use them individually or chained - many, many tone/boost combos possible. Fantastic chunky drive when chained together. Both circuits are properly isolated and filtered, resulting in a "stacked" pedal that's much quieter than chaining together separate pedals. Internal battery clip for power, although use of a single high quality "Boss style" external 9v "center negative" adapter is recommended.
