EVERYBODY LOVES A GOOD BOOST!
This Pedal uses a Pair of 1n4148 Diodes not Zener.
This is the perfect preamp pedal. The volume knob is a negative-feedback control styled after classic 60's recording console inputs. (so YES it does Crackle!) Most vintage guitars suffer from steadily deteriorating magnets in their pickups, since permanent magnets aren't really forever. The Fat Cock's input impedance is so high (>5 Meg) that it refuses any current flow from your pickup... maintaining the most magnetic field around each string, so you can hear exactly what your pickup sounded like the day it came off the winder. The ouput level can exceed 8 volts peak, and when it finally distorts, the wave is shaped like triode overload, not fuzz. It's so transparent no one will be able to tell you're using a pedal. Perfect for making the most of a classic amp and guitar, because it simply makes your guitar bigger and pushes the amp harder, causing natural overload. This sound can be the solution to the 'disappearing guitar' effect you get sometimes on stage when you stomp on your distortion and sound weaker. When cranked, it sounds much louder than a fuzz or distortion under stage conditions.
