From the vendor
Project overview
Inspired by Supro Fuzz. The Super Bro FUZZ has elements from some of the most admired fuzz boxes in history.
Introduction
This pedal gives you the dynamics of a Fuzz Face, the unparalleled sustains from a Big Muff, loads of harmonics from a Tone Bender while the EQ behaves like the ones on the Supro amps. Sounds pretty promising, and he’ll, yeah, it is.
Also, it’s a good entry into Germanium fuzz projects since only the first stage is Germanium while the others are easy to source silicon transistors. This will allow you to experiment with different hfe’s and how their gain affects the overall tone without busting the bank.
This circuit features an internal Bias Trimpot that regulates how much voltage is feeding on the first germanium transistor, allowing you to experiment with different transistors and configuring your favorite settings for an exquisite tone.
Don’t miss this touch-sensitive, vintage 60’s flavor amalgamated with a destructive modern sound. The Super Bro FUZZ delivers the goods while keeping your noise floor amazingly low.
