breakfast audio - concrete fuzz V2

"The Concrete Fuzz V2 is a doomy fuzz based on the dam meathead topology.

V2 takes the filter tone knob setting from V1 and applies it to two different bias settings on the second transistor which is selectable by the side switch. Both selections provide a range of tones from stoner doom crunchiness and washed out blooms of fuzz with the bias differing between brightness and bass levels. 

Designed with full guitar volume in mind and a driven amp clean tone."

"...One side was like a boost and one side was like an overdrive and you could use them both together If my memory right. ... I vaguely remember him saying it was the shell from an old field testing unit from the phone company."
