The Electro-Harmonix Oceans 12 elevates reverb with two completely independent stereo channels that can operate in parallel or in series. Twelve different algorithms—including Hall, Spring, Shimmer, Reverse, and Echo—offer endless possibilities for spatial sound creation. Each channel has separate control over pre-delay, EQ, and modulation, allowing for detailed shaping. With stereo inputs and outputs, tap-tempo, and expression input, this is a professional reverb machine for stage, studio, and sound design.
