Electro-Harmonix has released the Oceans Abyss Advanced Reverb Laboratory, a stereo reverb pedal that replaces the Oceans 12 as its flagship reverb workstation¹. Gearnews reported the pedal on May 15, 2025, priced at $495²; Guitar World and MusicRadar both reported it available now at $495³⁴.

The pedal runs two independently programmable reverb engines, each with 10 reverb algorithms, presented in mono or stereo⁴. The onboard reverbs are Hall, Spring, Shimmer, Room, Plate, Reverse, Dynamic, Auto-Infinite, Polyphonic and Resonant¹. Guitar Pedal X describes the Polyphonic mode as offering two configurable bidirectional pitch-shifts within the reverb tail³. Each engine has its own controls: sliders for Blend, Low and High, knobs for Pan, Pre-Delay and Time, and buttons for Edit, Moment and Tails⁴.

Up to eight effects blocks can run together, two for reverb and six for effects⁴. The additional effects are digital, analog and tape delays, tremolo, chorus, flanger, phaser, graphic EQ, saturation, bit crusher, volume and an external FX loop¹². The stereo FX loop can be placed anywhere in the signal chain¹. There are 128 presets, navigable via MIDI or the trio of footswitches¹. Holding footswitches A and B engages Infinite Hold³. The footswitches are dual-action, configurable for momentary or latching operation¹.

Connections include stereo input and output, 5-pin MIDI In and Out, expression/CV input, a footswitch jack for up to three external footswitches, and USB-C for the EHXport app²¹. Sample rate conversion is 96kHz/24-bit¹. The pedal measures 18 x 14.6 x 5.7cm and ships with a 9.6V DC 500mA power supply¹³.

Gearnews counts seventeen reverb types, listing Spring, Plate, Dynamic, Auto-Infinite, Shimmer, Polyphonic and Resonant twice each², while Guitar Pedal X and MusicRadar describe 10 reverbs¹⁴.
