The JHS Coyote is a specialized octave fuzz and swell pedal that serves as a faithful recreation of the obscure Moonrock Fuzz by G.S. Wyllie. It utilizes an unconventional transformer-driven circuit topology where the transformer acts as an inductive element to shape the fuzz character rather than just generating the octave. The interface features a single "Mode" knob that sweeps through three distinct sonic zones: a gated, reverse-tape "Swell" at lower settings, a rich Tone Bender-style "Fuzz" at noon, and a snarling "Octave" up effect at maximum. This design emphasizes extreme touch sensitivity and cleans up effectively using the guitar's volume knob. It is housed in a standard enclosure and omits complex toggles to focus on the unique interactive relationship between the player's dynamics and the transformer circuit.
