The Drunk Beaver Disambiguation is a hybrid Rat/Big Muff - taking two of the most iconic distortion and fuzz pedals in rock and slamming them together for some gnarly sounds while retaining the character of your guitar.
The Rat-style gain stage uses a UD1408A op-amp manufactured in Kyiv; it's a Soviet-era clone of the famous LM308 chip found in the US-built Rat.
Combined with two subsequent gain stages based on the Russian Big Muff (using NOS Soviet KT3201EM transistors and KD521 diodes), the Disambiguation delivers a godly mid-hump and evoke the sound of a vintage Rat running full-tilt into a thick and raucous Red Army Big Muff.
The tone stack is based on the Rams Head Muff, and Vitalii has used a JFET output stage for valve-like warmth and response.
Distortion - Affects amount of gain
