Sola Sound Tone Bender MK1

Unknown brand · pedal

The Sola Sound Tone Bender MK1, designed by Gary Stewart Hurst in 1965, was the first Tone Bender fuzz, built as a louder, more sustaining answer to the Gibson Maestro FZ-1 Fuzz-Tone. Its three-transistor circuit runs on 9V rather than the FZ-1's lower voltage, giving it a raw, harmonically rich, high-gain fuzz that stays surprisingly clear on chords for a fuzz of its era. It is notably reactive to different pickups, producing a tasteful chime on single coils and a distinctive gating effect in the low end with hotter humbuckers. Fewer than 100 original units were built, some as custom jobs for Jeff Beck and Jimmy Page, and it was famously heard on The Yardbirds' Heart Full of Soul.
