Description

The Oceans Abyss expands on Electro-Harmonix’s highly acclaimed reverb technology to deliver a truly immersive effects workstation. The pedal is centered around dual reverb engines that are independently programmable with full-stereo algorithms including Hall, Spring, Shimmer and more. Place these reverbs into a customizable signal path with additional FX blocks like Delay, Chorus, Tremolo, or Bit Crusher for a completely unique soundscape building experience.

Electro-Harmonix has paved the way for powerful, accessible reverbs since the release of the original Holy Grail and now we’ve pushed the envelope deeper with the fully-equipped Oceans Abyss. Featuring a customizable signal path with up to 8 effects blocks, the Oceans Abyss can be configured as individual reverb, modulation, EQ, delay, bit crusher, saturation or volume effects, or as countless combinations for incredibly creative effect shaping. From a simple Spring reverb to a lush stereo field featuring stereo hall and shimmer reverbs, chorus, delay, overdrive, and tremolo, you can go from surf to shoegaze instantly, without breaking a sweat.

Deep parameter editing is accessible via the high-visibility OLED display with multiple graphical views and easy-to-read designs. Expression/CV control over nearly every parameter gives artful control of your effects and dynamics. Fully-stereo I/O plus an FX Loop allows for use with any instrument, recording set up, or live rig. 128 programmable presets via onboard footswitching or MIDI ensure perfect recall in all performance situations. MIDI IN/OUT ports with MIDI IN support of PC, CC, and Tempo Clock expand the already immense talents of the Oceans Abyss. Connect with UBS-C to Windows or Mac for effects editing, preset management, and more with the free EHXport™ app (coming soon).

Guitar Pedals

Guitar pedals are compact effects units that shape and enhance a guitar’s sound, sitting between the instrument and the amplifier. They include gain pedals like overdrive and distortion, modulation effects such as chorus and tremolo, time-based effects like delay and reverb, and essential utilities including tuners, compressors and loopers. Understanding basic things such as pedal type, signal order, power requirements and intended use helps players choose pedals that suit their style, setup and playing environment.

Chorus

Chorus is a modulation effect that thickens and widens a sound by duplicating the signal, slightly detuning it, and modulating its pitch over time. This creates the impression of multiple instruments playing together, resulting in a rich, shimmering, and spacious tone.

It is commonly used on guitar, bass, and keyboards to add movement and depth, working especially well with clean or lightly driven sounds. Chorus became strongly associated with 1980s music but remains widely used across pop, rock, ambient, and modern styles for its ability to make a sound feel fuller and more animated.

Delay

Delay is an effect that records the guitar signal and plays it back after a short period of time, creating an echo or repeat. By adjusting the time, feedback, and level, delay can add subtle depth and space or produce rhythmic, expressive repeats that enhance lead lines, ambient textures, and overall atmosphere.

Reverb

Reverb (short for reverberation) is an audio effect that simulates the natural reflections of sound in a physical space. When you play in a room, hall, or cathedral, the sound waves bounce off the walls, ceiling, and floor, creating a sense of depth and ambience. Reverb pedals and processors recreate this effect electronically, allowing guitarists and producers to shape how “big” or “live” their sound feels. From short, springy echoes that mimic vintage amp tanks to lush, atmospheric washes used in ambient or shoegaze music, reverb adds dimension and realism — turning a dry, flat tone into something immersive and expressive.

Tremolo

Tremolo is an effect that creates a rhythmic pulsing by varying the volume of the guitar signal up and down. It can be subtle and smooth or choppy and pronounced, adding movement and texture to clean tones and is commonly associated with classic amps and vintage-style sounds.
