Description

Edit description

Introducing the Electro-Harmonix Oceans 12, your ticket to a world of sonic possibilities and unparalleled flexibility. This dual stereo reverb pedal is a processing powerhouse, giving guitarists and keyboardists the opportunity to craft lush, dramatic soundscapes. Equipped with two separate reverb engines that can run in parallel or series, each boasting 12 distinct reverb types, the Oceans 12 is a versatile tool for any musician.

The Infinite Reverb Mode and the Tide Control are standout features of this pedal.

The Tide Control offers studio-level control over stereo imaging, altering the stereo width of the reverb from narrow and focused to wide and spacious.

Adding to its versatility, the Oceans 12 includes an expression pedal input that can control multiple parameters in real time. This lets you subtly tweak the reverb sound or dramatically transform it for dynamic, interactive ambient textures. With 24 presets and a Tails switch that allows reverbs to decay naturally, the Electro-Harmonix Oceans 12 is a feature-packed pedal that offers endless sonic possibilities.
