Six distinct high end reverb styles in a standard sized MXR box. Each reverb style is as richly detailed as any found in the highest-end rack units: PLATE provides a shimmering smooth wash of space. SPRING is a perfect recreation of the classic amp-based effect. EPIC is a combination of analog-tone delay lines and complex modulation. MOD throws down plate spaciousness with rich modulation. ROOM adds body and projection to your guitar tone at shorter decay times while longer decay times yield rich organic space. PAD provides a unique combination of sub-octave + octave-up with echoes + - shimmer" + synth/organ modulation + reverb. Connect a Dunlop DVP Series volume/expression pedal to toggle and blend between configurations. 100% wet mode, stereo input and output capability. Selectable true relay or trails bypass modes. Cannot be powered by a battery. Supplied with 9v AC adaptor (ECB003).
