JuiceJawn — Analog Envelope Filter

An ode to the great envelope filters of the past — the JuiceJawn chases the Mutron III sound with a handmade optocoupler at its heart, then wraps it in modern control and true one-of-a-kind looks.

The sound

A fully analog filter that listens to your dynamics: dig in and it quacks, back off and it blooms. Gain, Envelope Sensitivity, and Q Peak knobs shape the sweep; two toggles flip filter range and sweep direction (classic up or reverse down). Internal trimpots fine-tune sensitivity to your instrument — guitar, bass, keys, or Moog (ask Eli).

The build

Hand-populated PCB, handmade optocoupler (the part you can’t buy), relay bypass — pick traditional or muted switching — and a hand-poured resin face that exists exactly once. Serialized and signed.
