JHS Pedals - Mary K – Legends of Fuzz

JHS Mary K – Legends of Fuzz

The JHS Mary K is a modern take on the classic Kay Fuzz Tone from the late 1960s, originally a low-cost variant of the Shin-ei/Univox Superfuzz. JHS has updated this iconic fuzz with knobs for full control and an expression pedal input, allowing guitarists to shape the Frequency in real time, just as the original treadle-based design intended. This pedal delivers rich, vintage fuzz tones with enhanced versatility for modern rigs, honoring one of the Edge’s go-to fuzz pedals.

Why Guitarists Love It:

The Mary K delivers classic 60s fuzz tone with modern flexibility. Its vintage-inspired circuit gives a thick, saturated fuzz, perfect for rock, psychedelic, or experimental sounds. Expression pedal compatibility allows dynamic control of the Frequency parameter, giving players hands-on, expressive possibilities that weren’t possible on the original treadle design.
