Electro-Harmonix Oceans 12
Electro-Harmonix · pedal
The Electro-Harmonix Oceans 12 is the larger sibling of the Oceans 11, featuring two simultaneous, independent stereo reverb engines that can be run in series or parallel for layered, dual reverb textures. It offers 24 presets, advanced stereo connections, a Tide control to alter the stereo image, a Lo fi control and an infinite attenuation control for evolving ambient soundscapes. Running two reverbs at once, it creates rich, complex spaces, from layered hall and shimmer combinations to wide stereo ambient washes. It suits ambient, post rock, worship and experimental players who want deep, dual engine stereo reverb with presets and creative routing in a single pedal.
What stands out
“The trade offs are that routing and balancing two reverbs adds real complexity and a learning curve, the pedal is larger and pricier than the Oceans 11, and players wanting a simple single reverb may find it more than they need”
