The Electro-Harmonix Oceans 12 is a dual reverb effect pedal that is easily intuitive and extensively expressive. Building off the smaller Oceans 11 reverb, the Oceans 12 packs in more features and settings to provide an encompassing reverb experience.

The Oceans 12 features twelve unique reverb effects that range from classic and familiar to deep and experimental. An intuitive interface allows players to easily dial in two independent reverb effects that can be used one at a time or in tandem. Series and parallel controls allow greater access to adjust reverb settings for deep tonal experimentation. Along with expression pedal compatibility and tap tempo function, the Oceans 12 encourages tweaking and tinkering both before and during performance.

The Oceans 12 features twenty-eight total reverb modes:

1. ROOM – Two Modes: Emulations of a lively room or performance hall

2. SPRING – Two Modes: Vintage Fender 6G15 tube reverb and EHX Holy Grail reverb

3. PLATE – Two Modes: Emulations of 1960s and '70s high performance metal plate reverb

4. REVERSE – Two Modes: Pure reverse reverb with true reversed echoes

5. ECHO – Three Modes: Digital delay with different echo rhythms

6. TREM – Three Modes: Classic volume envelope with various shapes with both wet and dry mix of hall reverb

7. MOD – Two Modes: Unique combinations and chorus of flange reverb

8. DYNA – Three Modes: Experimental swell, gate, and duck reverb algorithms

9. AUTO-INF – Three Modes: Auto-infinite reverb with optional chorus or flange that responds to changes in notes played

10. SHIMMER – Two Modes: Different configurations of octave-shifted reverb

11. POLYPHONIC – Two Modes: Configurable bi-directional pitch shifts

12. RESONANT – Two Modes: Reverb with configurable self-oscillating filters

The Electro-Harmonix Oceans 12 is a fully-equipped reverb pedal for extended experimentation in practice and reliable performance onstage. The features of the Oceans 12 shine with time as it functions with great utility for any player. With a vast landscape to discover, the Oceans 12 provides great direction and deep functionality for exploration.
