3rd Dimension Chorus is a unique type of “motionless” chorus effect that reproduces that instantly recognizable ‘80s clean tone. It’s full and lush, and expands your tonal range with a 3-dimensional feeling that is at once rich and sweet, as well as shallow and smooth. The pedal has no knobs to fiddle with – just 4 preset buttons ranging from “just a bit” to “quite substantial”. The pedal takes its inspiration from the classic ‘80s analog studio chorus guitar tones found on thousands of recordings – thick, lush, and crystal clear. It even responds to your playing dynamics – either dig in on some meaty chords, funk out on some crispy double-stops, or create huge sounding, finger-picked arpeggios. You’ll quickly find some recognizable settings with the 4-button interface. You can save the knob twisting for your other gear; the peda; features 4 tasteful and easy-to-use preset buttons, providing an amazing array of great tones. You can even coax out 16 different presets from the pedal by combining the 4 buttons in different ways (there’s even a hidden preset that’s only active when the buttons are in the up position).
