Description
Overview
The Electro-Harmonix Oceans 12 Dual Stereo Reverb is a powerhouse of spatial effects, serving as the expanded “big brother” to the Oceans 11. This professional-grade pedal features two simultaneous, independent stereo reverb engines, allowing players to blend complex textures and deep atmospheres with unprecedented flexibility. Whether you need a subtle room ambience or a massive, evolving wash of sound, the Oceans 12 provides a comprehensive toolkit for sonic exploration.
Key Details
The Oceans 12 is designed for maximum control over the stereo field and signal flow, offering a wide array of synthesis and modulation options:
- Dual Engine Architecture: Run two different reverbs simultaneously with series or parallel routing options to shape how the effects interact.
- Advanced I/O: Supports full stereo in/out or mono send/return configurations, including pre- and post-reverb options for flexible pedalboard integration.
- Tide & Lo-Fi Controls: A dedicated Tide Control allows for precise stereo image alteration, while the Lo-fi Control adds grit and character to the reverb tails.
- Performance Tools: Includes an infinite attenuation control, 24 onboard presets, and a Tails switch to choose between a natural fade-out or an immediate stop when bypassing.
- External Expansion: Features an input jack for external expression pedals and 3-button footswitch control for hands-free manipulation.
Use Cases
With 12 distinct reverb families, the Oceans 12 adapts to any musical environment:
- Studio Classics: Use Room (Lively Room/Performance Hall), Spring (1962 Fender® 6G15 or Holy Grail emulations), and Plate (60s/70s studio metal plates) for timeless, organic spaces.
- Ambient & Cinematic: Create ethereal landscapes using Shimmer (octave-shifted washes), Polyphonic (bi-directional pitch shifts), or Resonant (tunable resonators and self-oscillating filters).
- Experimental Textures: Explore Reverse (reverse reverb and echoes), Dyna (Swell, Gate, and Duck), and Auto-Inf (intelligent crossfading reverb washes that react to your playing).
- Rhythmic & Modulated: Add movement with Echo (digital delay feeding a plate), Trem (volume envelopes with hall reverb), and Mod (chorus and flange combinations).
Installation
Integrating the Oceans 12 into your signal chain is straightforward. For standard setups, connect your instrument to the input and the output to your amplifier. For those seeking a wider soundstage, utilize the stereo inputs and outputs. If using a wet/dry setup, the mono send/return allows you to isolate the reverb effect. Ensure you use a high-quality power supply to maintain the stability of the dual stereo engines.
Compatibility
The Oceans 12 is a physical hardware effect pedal compatible with any standard electric guitar, bass, or synthesizer signal chain. It is designed to work with standard 1/4″ TS/TRS cables and supports external expression pedals for real-time parameter control.
