The R2R Electric Supa MKII is a circuit inspired by the Sola Sound Tone Bender MKII and the Marshall Supa Fuzz, which were essentially the same pedal made by the same people under two different companies, although the circuit of the later Supa Fuzz slightly evolved with time. This pedal combines the two circuits, producing more volume and a wider sonic palette.
Although this is a new pedal, it’s already quite rare due to the scarcity of OC75N GE transistors and fetches on Reverb for $450 or more, used.
Available also in a regular Hammond 1590p1 enclosure with only 2 controls (and fixed bias), the Supa MKII is a hand wired fuzz made almost exclusively with vintage components, including
- 3x Black Glass or TO-1 Vintage & NOS germanium transistors
- Vintage CTS, Centralab or Stackpole potentiometers
- Philips or Sprague electrolytic capacitors
- 1960’s Wima TFF, Philips Mustard Cap or ERO Foil capacitors
- 1960’s / 70’s Piher 1/2 carbon film resistors
- Vintage style Carling footswitch

R2R Electric Supa MKII, Builder’s Notes
The Supa MKII Fuzz is my take on both the Sola Sound Tone Bender MKII* and the Marshall Supa Fuzz*. These pedals represent my favorite combination of component choices and modifications of these two classic fuzz circuits.
These will be available in two forms:
- Vintage Rotosound style enclosure with 3 controls: Level, Attack & Bias
- Hammond 1590p1 enclosure with 2 controls (Level& Attack) with fixed bias
Each Supa MKII Fuzz features:
- 3x Black Glass or TO-1 Vintage & NOS germanium transistors
- Vintage CTS, Centralab or Stackpole potentiometers
- Philips or Sprague electrolytic capacitors
- 1960’s Wima TFF, Philips Mustard Cap or ERO Foil capacitors
- 1960’s / 70’s Piher 1/2 carbon film resistors
- Vintage style Carling footswitch
- Handwired on phenolic replica pcb
- Daka-Ware control knobs
*Due to the design of this vintage Fuzz circuit, these pedals work best placed first in your signal chain. These units do not work well with buffers or buffered bypass pedals going into the input. This will cause the effect to sound thin with a significant volume drop*
**These effects can be powered by 9v battery (included) only*
***To preserve battery life, please unplug the input jack after use**
