JHS Pedals Mary-K Fuzz Pedal

Experience Vintage Fuzz with JHS "Legends of Fuzz" Mary-K

The JHS "Legends of Fuzz" Mary-K is a testament to the rich history and legacy of fuzz circuits. Part of the "Legends Of Fuzz'' series, this pedal pays homage to the iconic Kay Fuzz Tone, originally released in the late 1960s. With a nod to its vintage predecessor, the Mary-K offers guitarists a chance to explore the raw, untamed sound that has shaped music for decades.

A Tribute to Vintage Innovation

Founded in 1931, Kay Musical Instruments made its mark in the guitar pedal market with its unique knobless, treadle-based pedals in the late 1960s. The Kay Fuzz Tone, a low-cost version of the Shin-ei/Univox Superfuzz, became a staple in the Edge's arsenal and continues to inspire guitarists today. Now, over five decades later, JHS introduces the Mary-K, capturing the essence of the original while adding modern features for enhanced control and versatility.

Expressive Control Options

While honoring the vintage design of the Kay Fuzz Tone, the Mary-K offers users the option to control the Frequency knob with an expression pedal. Compatible with various expression pedals, such as the Nektar NX-P and Roland EV-5, this feature allows for dynamic and expressive manipulation of the fuzz effect. However, it's essential to note that some expression pedals may introduce noise in high electromagnetic interference environments, so plastic chassis expression pedals with short cables are recommended to minimize unwanted noise.
