Eary Monsterpiece Fuzz #293 from 2007 using 2 BC 108 B, volume, bias, gain controls.
Silicon transistors. Works perfect in Very Good condition w/ velcro on bottom.
The Monsterpiece NPN Fuzz is the Monsterpiece that started it all. It has undergone several transformations over the years, and I think that the current version is the definitive version. This is a 2 transistor silicon fuzz utilizing either BC108 or BC109 transistors (I have both, and use whatever sounds best in each individual pedal).
The circuit is based on the classic fuzz face circuit, but is by no means a straight up clone. This is by far one of the most musical, dynamic, and responsive silicon fuzzes you will ever hear. A world of fuzz tones lurk within.
