FERROTANK
A spring reverb you play with your hands.
Click the springs and they answer with real recordings of real steel — never the same twice. Behind them, the whole tube circuit that defined surf guitar. The drip is the point.

Audio demos are being recorded — dry against wet, same take, no cherry-picking. The dev log hears them first.
Click the springs. They answer.
The spring tank on the panel is playable: click or drag the springs and they ring with real recordings of real steel — never the same twice. They model springs. We recorded ours.
The whole tube circuit
Not an impulse response, not a hall algorithm. A model of the whole tank: a tube preamp that drives the springs, the springs with their unmistakable chirp, and a vintage bias-style tremolo on the way out.
DWELL, DRIP, DECAY
Turn DWELL up and the tube overdrives the springs. Open DRIP and the chirp stretches into a long metallic drip. Hit it hard enough and it crashes — because that’s what a real spring tank does.
Four tanks
Switch TANK and the whole spring geometry changes underneath — different lengths, different resonances, different drip.
Bright by choice
Two knobs from Dick Dale to Pharoah Sanders: a subtle wash behind a clean guitar at one end, full drip-and-splash surf crash at the other. Guitars, keys, drums and synths all take to it.
10 parameters, 5 presets
Everything automatable, plus a playable tank. Simple on purpose.
The 6G15 reverb unit (1961–1963) was a standalone, tube-driven spring reverb built to sit ahead of a guitar amp. Its own tube preamp drove a spring tank hard, producing a dripping, splashy chirp with far more character than the reverb built into the amps of the day.
That sound became one of the defining textures of early-1960s surf music — the reverb most associated with Dick Dale — and it has stayed a studio favourite for surf, garage and cinematic guitar ever since.
Ferrotank models the character of that circuit — the tube warmth, the spring chirp, the tank resonances — not any specific artist or recording. Real recordings and impulse responses were used only as a tuning reference.
