BPC Professional MKII Tone Bender

The BPC MKII Tone Bender  OC81D is a detailed replica of the 1966 PROFESSIONAL MK II Tone Bender pedals created by Gary Hurst. The circuit unlike the MK 1.5 had a 3 Transistor circuit which, based on production/supply comprised of either  OC75’s or OC81D transistors. This OC81D Loaded MK II can be heard on many Jimmy/Led Zeppelin Tracks such as ‘Whole lotta love’. This was the pedal seen being used by Jimmy on the recent ‘It Might get loud ‘ documentary.

Many people ask us how each transistor differs in tone. Everyone’s ears are different but here is our small guide

OC75: Bright and high gain, snappy in tone, sounds raspy in a 3 transistor circuit such as the MKI.5
OC81D: Smooth gain lots of saturation
2G381: This is what gives the MKI its sag when you bend a note. They are key to the MKIs Tone.
OC44: Bright and Driven Tone
OC71: More Shrill and Glassy then an OC44
ACY41: Bright, Raspy, and in your face (ideal for fuzz)
2n4061: Silicon-based, used in the Shatterbox for crazy amounts of thick fuzz
