The Mary-K is JHS’s modern reinterpretation of the classic Kay Fuzz Tone from the late 1960s, reimagined with added control and flexibility for today’s players. It delivers gritty, vintage-inspired fuzz tones with adjustable frequency and output, allowing musicians to dial in expressive textures ranging from classic spitty fuzz to more saturated sustain. Unlike the original knobless design, the Mary-K includes robust controls and an expression pedal input to sweep the frequency parameter in real time, offering dynamic tonal shaping while retaining the character of the iconic fuzz that inspired it.
