This is a vintage 1967 Marshall Supa Fuzz (model no. 1975) electric guitar effects pedal. This extremely rare early variety (1st version) has the exact same circuit as the famed Professional Mk II Tone Bender and also features: a very early perforated hand-wired circuit board, a non-raised/non-script silk-screened ‘Supa Fuzz’ logo, and (3) OC81D germanium transistors. This extremely rare pedal also features simple controls for Volume and Filter and is housed in an angular cast aluminum box with a classic hammerite finish. It is estimated that less than 50 first generation Marshall Supas were originally produced, which may be fewer than both the total Vox and Sola Sound MK IIs, making the Marshall the rarest of its kind! Tones from this pedal range from a subtle and natural RangeMaster-esque overdrive sound, to a monstrous, rich wall of full-range fuzz. Most vintage fuzz connoisseurs consider the Marshall Supa Fuzz to be the most musical and expressive fuzz pedals ever made. Identical to a Sola Sound MKII, the Marshall is a one-trick pony (in the best sense of the expression) with a best-in-show trick, as it absolutely masters and dominates a full-range and evenly balanced fuzz spectrum. Displaying an aggressive and feedback-provoking fuzz, while lacking in the overly splattery nature of later fuzz units caused by choking and limiting the output, the Marshall Supa is an extremely organic, expressive, and uncompromisingly musical pedal. With natural lyrical qualities, the Marshall Supa is as good as it gets for leads. You can reference Pete Townshend’s early fuzz tone, as well as, Ron Asheton’s (The Stooges) to hear the Supa Fuzz in a more recognizable context.
This particular example is in nice all original condition. All the electronics, knobs, and feet are original, though the screws have been changed. The pedal was professionally converted from the use of a PP4 English 9v battery to a modern 9v battery, and one original leaky capacitor was removed, but is included.
