Abyss is right. Electro-Harmonix’s Ocean’s Abyss, with two stereo reverbs and 10 reverb types, is fundamentally a reverb pedal. But it is deeper than that. Much, much deeper. EHX calls the Abyss an Advanced Reverb Laboratory. I’d venture that it is more like a reverb-centric multieffects unit, because the Oceans Abyss enables you to add effects that include chorus, distortion, delay, and bit-crushing to the expansive array of reverbs. But I’m not even sure my modified description does the pedal justice. It is a sound-design machine of impressive power—especially if you have the time and will to explore the breadth of its functions.
