Electro-Harmonix OCEANS ABYSS Advanced Reverb Laboratory Guitar Effects Pedal

Dive deeper into the depths of ambience with the Oceans Abyss Advanced Reverb Laboratory! The Oceans Abyss expands on Electro-Harmonix’s highly acclaimed reverb technology to deliver a truly immersive effects workstation. The pedal is centered around dual reverb engines that are independently programmable with all-new full-stereo algorithms including Hall, Spring, Shimmer and more. Place these reverbs into a customizable signal path with additional FX blocks like Delay, Chorus, Tremolo, or Bit Crusher for a completely unique soundscape building experience. Electro-Harmonix has paved the way for powerful, accessible reverbs since the release of the original Holy Grail and now we’ve pushed the envelope deeper with the fully-equipped Oceans Abyss. Featuring a customizable signal path with up to 8 effects blocks, the Oceans Abyss can be configured as individual reverb, modulation, EQ, delay, bit crusher, saturation or volume effects, or as countless combinations for incredibly creative effect shaping. From a simple Spring reverb to a lush stereo field featuring stereo hall and shimmer reverbs, chorus, delay, overdrive, and tremolo, you can go from surf to shoegaze instantly, without breaking a sweat. Deep parameter editing is accessible via the high-visibility OLED display with multiple graphical views and easy-to-read designs. Expression/CV control over nearly every parameter gives artful control of your effects and dynamics. Fully-stereo I/O plus an FX Loop allows for use with any instrument, recording set up, or live rig.
