The Electro Harmonix Oceans 12 features two simultaneous, independent, stereo reverb engines, series and parallel control for the dual reverbs, 24 presets, and advanced I/O allowing for stereo in/out or mono send/return with pre and post reverb options. The pedal also includes a new Tide Control for stereo image alteration, a Lo-fi Control, an infinite attenuation control, an input jack for external expression, and a 3-button footswitch control. A Tails switch provides a choice of whether the reverb effect fades out naturally or stops immediately when the pedal is switched to bypass. In most settings, the pedal can produce infinite reverb, which can be played with a different reverb effect.
Room ReverbTwo modes of reverb algorithms are modeled after a living room and a spacious performance hall.
Spring ReverbTwo modes vintage 1962 Fender 6G15 tube reverb emulation and the spring algorithm from the EHX Holy Grail.
Plate ReverbTwo modes reverb. Two emulations of the smooth, metal plate reverb often used in high-end recording studios during the 1960s and 1970s.
Reverse ReverbTwo modes reverb. A reverse reverb effect as well as reversed echoes.
Echo ReverbThree modes reverb. A digital delay with various echo rhythms feeding into a plate reverb.
Trem ReverbThree modes reverb. A classic, periodic volume envelope with various shapes is applied to a hall reverb's wet and dry mix.
Mod ReverbThree modes reverb. A combination of chorus and flange reverb creates rich reverb tails.
Dyna ReverbThree dynamic, experimental reverb algorithms swell, gate and duck.
Auto-Inf ReverbThree modes auto-infinite reverb (with optional chorus or flange) that listens to the playing and crossfades to a new reverb wash upon detection of newly struck notes.
Shimmer ReverbTwo modes of reverb with two configurations of a rich octave-shifted reverb wash.
Polyphonic ReverbTwo reverb modes with two configurable bi-directional pitch shifts add dimensionality to the reverb tail.
Resonant ReverbTwo reverb modes are excited by tunable resonators and configurable self-oscillating filters on the reverb tail.
