Coil is a spring reverb built from the ground up around the thing that makes real spring tanks so good: they're physical. The springs stretch, resonate, build up energy, and get hit, and when you kick the tank, you hear it. There are no impulse responses inside Coil. The springs themselves are simulated while you play. Change the physics and you change the sound. TWO TANKS, TWO PERSONALITIES • LONG — big, slow, heavy springs. More depth, more wobble, more of that surf-era drip. • SHORT — tighter springs with a brighter, immediate response. Less wash, more snap. KRAANG! Hit the pedal and the springs respond with a burst of metallic chaos. Because they're physically simulated, what comes back depends on where the springs are in their motion when you land. Try it while the reverb is already ringing. It's ridiculous. It's also extremely useful. THREE KNOBS, NO MYSTERY • MIX — how much spring you want. • TONE — how fast the top end dies in the steel. Not an EQ: you're changing the behaviour of the spring itself. • DWELL — how long the springs keep moving. AND THE JEWEL Tap it and the whole thing goes through a measured amp stage — presence, grit and all. Nobody will tell you this is there. WORKS EVERYWHERE • AUv3 for GarageBand, Logic Pro, AUM and any Audio Unit host • Standalone app — plug in and play, no DAW needed • MIDI learn on every control • One purchase: Mac, iPad and iPhone No giant metal tank. No springs to break. No road case. A spring you don't have to haul around.
