Unlike the movie it shares a name with, the Electro-Harmonix Oceans 12 expands and improves the formula of its predecessor. With 29 reverbs ranging from classic to unconventional, dual reverb engines for separate or simultaneous reverbs in series or parallel, and full stereo functionality, the Oceans 12 offers expansive reverbs with a high degree of control over the shape and character of those sounds.

29 Reverbs

With a name like Oceans 12, you'd expect there to be at least one more reverb sound than the Oceans 11.  In fact, with an extra reverb type and multiple modes per type, the Oceans 12 packs in 29 distinct sounds! You don't just get 29 sounds in isolation either, with 2 reverb engines you can use them individually or combine two of them in series or parallel for richer and more complex sounds.

From traditional to experimental, the Oceans 12 has reverb to suit every style. On the more conventional end are the Room, Spring, Plate, Echo, and Trem types which offer vintage sounds and can add subtle life to your tone. All the reverb types in the Oceans 12 have 2 or 3 modes which change the character of the reverb for a different sound.

Moving into more modern and experimental territory are the Mod, Reverse, Dyna, Auto-Inf, Shimmer, and Polyphonic modes which are great for shoegaze and ethereal, ambient-sounding styles. These modes feature reverbs that can, fade in reverse, mix chorus and flange sounds, utilise experimental reverb algorithms, octave-shift, and pitch-shift. From these modes you can get wild, out-of-this-world sounds, taking you into less-familiar sonic territory.

New to the Oceans 12 is the Resonant reverb type which gets its character from tuneable resonators and has reverb tails affected by configurable self-oscillating filters.

Controls and Functionality

As the number of reverbs has increased, so has the control and functionality. The main feature here is the stereo functionality of the Oceans 12. With the I/O you can run the pedal in stereo, or as mono with a mono send/return (pre or post reverb optional). There's also an expression pedal/footswitch jack for further expanding the functionality of the pedal.

You still get the FX Level, Time, and Tone controls for shaping your core sound, but you also get a Predelay for adjusting the time between your dry sound and the reverb sound, a Lo-Fi control, and an INF Level for controlling infinite attenuation. With stereo functionality comes stereo controls with a Send Level control, and a Tide Control for adjusting the stereo imaging. In addition, there's a Tails button that allows you to switch between a hard cutoff or natural decay when you bypass the pedal.

Reverb Types

  • ROOM – two modes: Lively room and spacious performance hall
  • SPRING – two modes: vintage 1962 Fender® 6G15 tube reverb emulation and the algorithm from the EHX Holy Grail pedal
  • PLATE – two modes: 60s and 70s studio-style metal plate reverbs
  • REVERSE – two modes: reverse-fade reverb and reversed echoes
  • ECHO – three modes: digital delay with various echo rhythms
  • TREM – three modes: volume envelope with different shapes
  • MOD – three modes: combinations of chorus and flange reverbs that create rich reverb tails
  • DYNA – three dynamic, experimental reverb algorithms: swell, gate and duck
  • AUTO-INF – three modes: auto-infinite reverb with optional chorus or flange (new reverb starts when a new note is struck)
  • SHIMMER – two modes: octave-shifted reverb wash
  • POLYPHONIC – two modes: configurable bi-directional pitch shifts
  • RESONANT – two modes: reverb from tunable resonators with reverb tails affected by configurable self-oscillating filters

Specifications

  • 2 simultaneous, independent, stereo reverb engines
  • Series and parallel control for the dual reverbs
  • 24 presets
  • Stereo in/out or mono send/return with pre and post reverb options
  • Tide Control for stereo image alteration
  • Lo-fi Control
  • Infinite attenuation control
  • Tap tempo to set your pre-delay time, echo time and more
  • Input jack for external expression and 3-button footswitch control
  • Equipped with a standard EHX 9.6DC200mA power supply

Chorus

A chorus pedal thickens and widens your tone by subtly duplicating your signal and shifting it slightly out of tune and time. The result is movement — shimmering cleans, liquid arpeggios, and that unmistakable 80s swirl that makes single notes feel fuller and chords sound expansive. From gentle sparkle to deep, watery modulation, chorus adds dimension without overwhelming your core sound.

Use it to bring life to clean passages, soften driven tones, or create spacious textures that sit beautifully in a band mix. Whether you’re after subtle depth or bold, warbling character, a chorus pedal is a simple way to make your guitar sound bigger, richer, and more immersive.

Delay

A delay pedal records your signal and plays it back after a set time, creating echoes that can range from tight, slapback repeats to long, atmospheric trails. It’s one of the most versatile effects, used to thicken tones, add rhythmic depth, or build spacious, ambient layers. Analogue delays offer warm, decaying repeats that blend naturally with your tone, while digital units provide pristine echoes with precise control over time, feedback, and mix levels.

From classic rockabilly and tape-style echoes to modern looping and shimmer effects, delay pedals have become essential tools for shaping sound. They can make solos soar, rhythms pulse, or transform simple chord progressions into cinematic textures. Whether used subtly to add dimension or boldly to create soundscapes, a good delay pedal can completely redefine the feel and atmosphere of your music.

envelope filter

An envelope filter reacts to your playing dynamics, opening and closing its sweep based on how hard you pick. Dig in and it quacks, ease off and it softens — delivering that unmistakable funk snap, auto-wah bounce, and touch-sensitive groove that feels alive under your fingers. It’s expressive, rhythmic, and full of character.

Use it to bring movement to clean riffs, add vocal-like sweeps to bass lines, or inject serious funk into your rhythm playing. From subtle shimmer to full-on 70s squelch, an envelope filter turns your picking hand into the control knob.

Expression

Expression pedals allow real-time control over specific parameters on compatible guitar pedals, such as volume, delay time, modulation depth, or filter sweep. Used with an expression input, they let players shape effects dynamically with their foot, adding movement and performance control that cannot be achieved with fixed knob settings.

New

This is brand new, fresh in, and a UK warranty is included. New Gear always comes from trusted UK music retailers.

noise gate

A noise gate pedal keeps your rig tight and controlled by cutting unwanted hiss and hum when you’re not playing. High-gain setups, stacked pedals, and long signal chains can introduce background noise — a noise gate steps in to silence it cleanly, letting your riffs start and stop with precision.

Use it to sharpen heavy rhythm parts, tame buzzing single-coils, or clean up complex pedalboards without sacrificing sustain. Dial it subtle for transparent control or tighter for that sharp, percussive stop-start effect — either way, it keeps your sound focused and professional.

Octave

An octave pedal shifts your guitar signal up or down by one or more octaves, blending the altered pitch with your original sound to create a fuller, more complex tone. It can add a deep, bass-like layer underneath your playing or a shimmering high octave on top for lead lines and solos. Classic analogue octave pedals often produce slightly gritty, organic sounds, while modern digital versions track more precisely and can offer multiple octave ranges.

Octave pedals are great for thickening single-note riffs, creating synth-style textures, or even mimicking bass parts when playing alone. They pair well with fuzz or overdrive pedals for massive, harmonically rich tones. Whether you’re after vintage Hendrix-style octave fuzz or a modern polyphonic sound that tracks chords cleanly, an octave pedal opens up a world of creative possibilities and adds real weight and character to your tone.

Pitch

Pitch pedals alter the frequency of your guitar signal, changing the perceived note or adding harmony. They can shift notes up or down by fixed intervals, create harmonies, or produce dive-bomb and whammy-style effects without a tremolo arm. Pitch shifters and harmonisers are great for thickening solos, simulating multiple guitars, or experimenting with creative, otherworldly sounds that expand your tonal range.

Reverb

A reverb pedal is like the rich sauce that ties every flavour on the plate into one smooth experience. It adds depth, warmth, and atmosphere — the sonic equivalent of a perfectly reduced glaze that lingers on the tongue. Whether you’re after the subtle ambience of a cosy café (spring or plate reverb) or the grand echoes of a cathedral (hall or shimmer reverb), this is where your tone breathes and expands. A touch of reverb can turn a dry sound into something lush and inviting — but pour on too much, and it’s all you can taste. Used with finesse, it’s the finishing touch that transforms your tone from plain to unforgettable.

Volume

Volume pedals control the output level of a guitar signal using a foot-operated treadle. They allow smooth volume swells, dynamic control during playing, and easy muting between songs. Volume pedals can be placed at different points in the signal chain to either control overall loudness or adjust gain and drive behaviour when positioned before distortion or overdrive pedals.
