DIY (Beavis Audio Research) - Four Knob Rat (FKR) Distortion/Overdrive

It's a beast of machine! The legendary RAT pedal on steroids! Literally. You can basically dial in a very broad spectrum of distortion. From slightly overdriven sound to a fully tight and punchy singing distortion. 

Controls: Volume, Filter(Tone), Gain, Lube
Toggles for sound sculpting:
Symmetry (Symetric - Asymetric) ; Clipping (Standard - Mod) ; Mod Mode (LED - MOS) ; Overdrive (LED - MOS) ; Lube (ON - OFF)

True bypass 3PDT switch. Green LED status light. Hand etched pcb and soldered by hand to last. 

The toggles are making a huge difference - some of them interact with each other and also with the control knobs. So one might need to spend a romantic day or two with the pedal to get to know each other. It's really versatile pedal and can suit for various type of music styles. Probably not modern metal but it depends on the amp and guitars you use. I have been using it in front of a 50w tube amp with good to marvelous results.

Please do not hesitate to contact me in case of any further inquiries.
