British Pedal Company Compact Series Zonk Machine Authentic Fuzz Guitar Pedal

This pedal is based on the original John Hornby Skewes Zonk Machine MKI pedal produced in Leeds, England, in 1965 – 1966. The Zonk machine is tonally similar to the MKI Tone Bender offering Driven Fuzz tones. Based on limited production originals are exceptionally scarce.

BPC Compact Series Zonk Machine MKI

• Small Casing Variant
• Fuzz and swell controls
• Specially selected transistors
• Limited production

*** Please note All Compact Series Pedals require their own isolated 9V power supply. This is due to the nature of the PNP Transistors which cannot be used with a daisy-chained supply.

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
