Imagine plucking or tapping the exposed springs on this desktop beast to coax out wild, percussive shrieks and evolving drones—it's like having a living, breathing feedback sculpture right on your desk.
This analog feedback instrument runs on reverb springs for its core sound generation, with a feedback path that includes a delay circuit (tweakable via Lag for time and Regen for repeats) and a resonant lowpass filter (Cutoff and Resonance knobs let you carve the tone). Feed it an external signal through the input jack, shape it with a preamp offering drive and a hard/soft clipping switch, then blend dry/wet levels before hitting the 3-band EQ. You've got two outputs: a main dry/wet mix and a reverb-only send, all powered by a standard 9VDC center-negative supply in a sturdy 11 x 6 x 2.25-inch enclosure. The front-panel controls line up intuitively along the bottom, and those springs are right there for hands-on manipulation to spark unique timbres.
Players dig its versatility as both a standalone tone generator for ambient drones and a spring reverb pedal for guitars or synths, praising the gritty saturation and physical interactivity in jams and recordings. A few note it shines brightest when paired with other effects for fuller chains, but the raw, organic feedback has hooked experimentalists everywhere.
