Features
Read full description

Coil brings the character of spring reverb into a compact, playable pedal. TWO TANKS Choose LONG for spacious, wobbling tails or SHORT for a tighter, brighter response. TWO ENGINES A uses physical spring modeling. B offers a lower-CPU vintage spring sound. Both follow the TANK switch. KICK THE TANK Tap the pedal body to strike the physical springs. You can also trigger Kick from your host, MIDI CC 83, or MIDI notes; velocity controls strike strength. THREE KNOBS DWELL sets decay, TONE shapes brightness and high-frequency damping, and MIX blends your dry signal with the reverb. CLEAN OR AMP Use the dedicated CLEAN / AMP switch to add the built-in amp stage. The lamp and artwork show the amp state. PLAY YOUR WAY Use Coil as an AUv3 audio effect in a compatible host or as a standalone app with an audio interface. The MUTED/LIVE control provides quick access to input muting. The in-app scroll guide explains controls and MIDI mappings. One purchase for Mac, iPad and iPhone.
