Electro-Harmonix Oceans 12 Dual Stereo Reverb

This second hand pedal is in very good condition

The Electro‑Harmonix Oceans 12 is one of the most ambitious, deep‑editing, studio‑grade reverb pedals you can put on a board. It takes the beloved Oceans 11 engine, doubles it, adds parallel/series routing, stereo I/O, advanced controls, and turns it into a full ambient workstation. It’s not a set‑and‑forget pedal, this is for players who want huge, sculptable, cinematic reverbs with real tweakability.

The Oceans 12 is a dual‑engine stereo reverb with:

• Two independent reverbs running in parallel or series
• 12 reverb types (each with multiple variations)
• Full stereo I/O
• Tap tempo for rhythmic reverbs
• Expression/CV input
• Presets
• A surprisingly deep editing system

 Sound & Reverb Engines

1. Hall / Plate / Room

These are cleaner and more hi‑fi than older EHX reverbs.
Hall is lush, Plate is bright and studio‑like, Room is natural and unobtrusive.
Great for everyday use.

2. Spring

EHX knows springs.
This one has the classic drip, splash, and wobble, very surf‑friendly and more authentic than most digital springs.

3. Shimmer

One of the better shimmers in this price range.
Not too metallic, not too synthetic, and you can blend two pitch intervals for more complex pads.

4. Polyphonic

This is where the pedal gets Smooth, synth‑like, and capable of massive ambient washes without glitching.

5. Echo / Reverse / Modulated

• Echo blends delay + reverb in a musical way
• Reverse is trippy and smooth, not choppy
• Modulated gives you chorus‑like movement without sounding cheesy

6. Dyna / Auto‑Inf / Trem

These are the creative engines:

• Dyna reacts to your playing (ducking, swell, gate)
• Auto‑Inf blooms into infinite pads
• Trem adds rhythmic pulsing to the reverb tail

These modes are where the Oceans 12 becomes a sound‑design tool.

 Dual Reverb Engine: The Big Deal

This is the Oceans 12’s defining feature.

You can run:

• Two reverbs in parallel (wide stereo ambient beds)
• Two reverbs in series (e.g., Plate into Shimmer, or Spring into Hall)
• Two different reverbs on left/right channels

 Controls & Editing

Surface controls

Straightforward enough for live use:

• Time
• Tone
• FX level
• Mode selector
• Tap tempo
• Infinite footswitch

Advanced controls

This is where it gets deep:

• Hidden parameters for modulation, pre‑delay, filtering, shimmer intervals, stereo width
• Preset system
• Expression mapping
• Routing configuration

If you enjoy tweaking, it’s a playground.

 Real‑World Use

Live

• Stereo spread is massive
• Presets make it gig‑friendly
• Tap tempo helps rhythmic ambient players
• Infinite switch is great for holding pads under solos

Studio

• Quiet, clean, and full‑range
• Dual engines make it easy to build layered textures
• Works brilliantly on synths and drum machines too

Home / Ambient

If you like cinematic, post‑rock, or ambient soundscapes, this pedal is basically a universe in a box.

The Electro‑Harmonix Oceans 12 is a powerful, flexible, and surprisingly hi‑fi reverb workstation. It’s perfect for players who want big ambient textures, dual‑layered reverbs, and deep editing options. If you’re an ambient guitarist, post‑rock player, or studio experimenter, it’s a gem.
