The MXR M300 digital reverb guitar effects pedal delivers six distinct high-end reverb styles, each exquisitely crafted and tuned by the award-winning MXR design team. It all comes in a standard-sized MXR box with a simple three-knob setup and a hi-fi analog dry path with a massive 20 volts of headroom thanks to Constant Headroom Technology. Each reverb style is as richly detailed as any found in the highest-end rack units and plug-ins, and all you have to do to step through them is push the Tone knob.

The PLATE setting provides a shimmering smooth wash of space that’s a go-to choice from the studio recording world. SPRING sets a new standard for truly authentic-sounding reverb without coiled metal—a perfect recreation of the classic amp-based effect, with the Tone control taking you from dark vintage amp spring, through classic jangle, to bright surfy splatter. EPIC is a unique combination of multiple interwoven analog-tone delay lines and complex modulation—perfect for solos from that hidden part of the lunar landscape. MOD throws down a plate-flavored spaciousness with richly organic modulation in the feedback path. The ROOM style adds subtle body and projection to your guitar tone at shorter decay times while longer decay times yield rich organic space that doesn’t wash out. PAD closes out the lineup with a unique combination of sub-octave + octave-up with echoes + "shimmer" + synth/organ modulation + reverb.

Connect a Dunlop DVP series volume/expression pedal to the expression jack to toggle and blend between two different knob setting configurations. The Reverb includes 100% wet mode, stereo input and output capability, and true relay or trails bypass.
