The Coyote is a complete replication of the obscure and very difficult to find Moonrock Fuzz by G.S. Wyllie.

The Swell / Fuzz / Octave control is the heart of this pedal. It sweeps continuously through three distinct zones — each one a different effect.

• Swell — At its lowest setting, notes bloom in with a gated, reversed-tape quality. A slow, breathing attack that rises up from silence. The final stage of the circuit is allowed to turn on gradually, easing the signal in and creating a natural bloom that responds to your picking dynamics.
• Fuzz — At noon, a fully realized fuzz tone. Not a Fuzz Face. Not a Big Muff. The texture sits in Tone Bender territory — rich low end, aggressive mids, the kind of fuzz that handles chords. Shoegaze. Psychedelic rock. Full and powerful. 
• Octave — Fully clockwise, the circuit shifts into aggressive octave-up territory. Intentionally uneven clipping emphasizes even-order harmonics, especially the second harmonic, pushing it above the fundamental to produce that snarling octave-up sound.

The transitions between zones are continuous.

The folks at JHS would also tell you that there's an another control: the volume knob on your guitar. I can confirm that this gives you an even greater range. I can add that playing with the tone knob has a profound impact too.

This pedal's origin story and its character are completely wild. It was so fascinating to me that I bought it on a lark. I remain fascinated by it, but I am a bass player and my personal playing style is not really the sweet spot for this pedal.

This pedal has never been used outside my home and comes with the original packaging.

Give it a good home, put it first in your chain, use its considerable powers for good (whatever that means to you).
