Marshall Model 1975 SupaFuzz Pedal

The Marshall Model 1975 SupaFuzz is one of the most revered and mysterious stompboxes of the 1960s and early 1970s. Built during the golden era of British guitar tone, the SupaFuzz was Marshall’s official take on the saturated, woolly fuzz sounds that were revolutionizing rock music. Simple in design yet massive in tone, the 1975 remains a crown jewel for collectors and fuzz connoisseurs.

Technical Overview

The SupaFuzz is a three-transistor, battery-powered fuzz unit, featuring:

  • Volume and Filter (tone) controls
  • ¼" input and output jacks
  • Footswitch-operated ON/OFF control

The pedal was known for its long sustain—often quoted at up to 15 seconds—and its aggressive midrange bite, capable of transforming any clean amp into a snarling, vintage-voiced machine. The circuitry was heavily influenced by the Tone Bender MkII, and many early versions used OC75 or similar Germanium transistors, contributing to its rich harmonic character and dynamic response.

Design and Construction

The Model 1975 featured:

  • Stove-enamelled metal housing
  • Large toe-activated footswitch
  • Minimalist control layout

Tonal Character

The SupaFuzz delivered a fat, saturated fuzz tone with rich lower mids, making it ideal for:

  • British blues-rock
  • Early psychedelic
  • Garage and proto-punk tones

Rarity and Collector Status

Original Model 1975 SupaFuzz pedals are among the most collectible of all vintage British effects, especially early units with original Germanium components. Because they were often used heavily and not widely distributed outside the UK, surviving examples are scarce—particularly those in working condition with intact graphics and original wiring.

In recent years, the SupaFuzz has been reissued and cloned by several boutique builders, but nothing compares to the tone and touch response of an original.
