The Fuzzolo is a raging beast of a fuzz. They managed to squeeze this wild thing into a small box to save real estate on pedal boards, and because they could. The Fuzzolo has two controls: Volume (post gain), and Pulse Width. The Fuzzolo is equally devastating on guitar and bass. These are small footprint pedals ideally suited for (but certainly not limited to) pedal boards. The Fuzzolo is a fuzz pedal that is in part derived from Mastotron and Woolly Mammoth.
