Product Overview
From the manufacturer:
Fuzz Dog GreaSi Box
Silicon version (i.e. much easier to source and to fettle) of a fantastic germanium fuzz box, giving what's been described as a 'greasy' fuzz tone.
The original has fixed resistors for the transistor biasing, and we think it mostly works. We've gone for a trimmer on the base of Q1 as standard, which is one spot that makes this sing or fail. Since we know some of you like to tweak more than others, we've added spots for another couple of trimmers for more baising and gain level. Choose those in the options below if required.
