The Drunk Beaver Taras Bulba is at its heart a vintage germanium Tone Bender MK II circuit, designed with an additional "Mk 1.5" mode plus exciting extras such as a Bias control and in-depth Pickup Sim section.
The Mk II Tone Bender is renowned for its smooth sustain thanks to its 3-transistor design, while the Mk 1.5 (an unofficial name given to the transitional 2-transistor circuit) was an inspiration for the Dallas Arbiter Fuzz Face.
The Taras Bulba utilises NOS germanium transistors: 1980s German MP20 & 1970s Soviet P416B.
