A WINDOW-RATTLING FUZZ CANNON

WHAT:  2-transistor silicon fuzz with input filter & master volume.
INSPIRATION:  We unearthed Vox built-in amp and guitar fuzz modules meant for silicon- now modernized and modified for a heavy, yet smooth fuzz!
CIRCUIT SAUCE:  Hand-picked low and medium gain transistors, sorted to give sustain and cleanup at your fingertips (guitar volume).  Fuzz intensity set just below max.  Low pass filtering of unwanted noise and a selectable high pass filter for fuzz flavor.
SOUND:  Heavy, sustaining fuzz or a brighter, more vintage fuzz.  This fuzz likes to be 1st in the signal chain, or at least before any buffer to preserve the cleanup effect.  

Filter Toggle: Up position- thick silicon transistor fuzz; Down position- less saturated fuzz with a bass cut that simulates a treble boost.

Made with silicon transistors sorted for gain and bias- a combination of 2n3053 and 2n2222A  🍑

Austere design, esoteric nomenclature.
