Is a Marshall labeled Sola Sound MKII circuit. The Marshall SupaFuzz MK2 is a highly sought after fuzz pedal, and we are so happy we have managed to demo one for you guys and girls. This one is dated to 1967 and has 3 OC75 transistors.
Next to the Dallas-Arbiter Fuzz face and Electro-Harmonix Big Muff, the Sola Sound MK2 circuit is among the most beloved fuzz circuits out there. The Marshall SupaFuzz version we have demoed, consists what is referred to in the industry as the “common” or “conventional” Mk2 circuit. Later versions of the Marshall SupaFuzz used OC81D transistors – we will try to add one of these to TonePedia in the near future.
The knob labelled as “Filter” on the Marshall SupaFuzz is actually the “gain” knob. Some of the early MKI SupaFuzz pedals made by Sola Sound did have a filter knob (and fixed gain) and while they changed the circuit, they did not change the lettering…
MKII Tone Bender pedals, such as this Marshall SupaFuzz, are an important ingredient of rock guitar sound. From the mid 60s until today, guitar players of the highest level relay on these old boxes for their fuzz tones. There are however, great current productions which enables you to get authentic fuzz tone at today’s standard quality. We recommend comparing the Marshall SupaFuzz MKII with newer fuzz pedals on TonePedia.
