MXR M300 Digital Reverb Pedal

Wash out and thicken your sound with the MXR M300 digital reverb pedal's six different reverb styles, including the "Pad" effect for a modulated shimmer.

The MXR Reverb 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 more shaded 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 line-up 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 read more 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.

This is a great pedal. I wanted a better and more versetile reverb than the spring tank in my amp and this turned out to be a great solution. There's a range of different flavors of reverb, all of which sound authentic and overall great sound quality. The pedal is really easy to use and dial in a good sound. I also really like the tap feature on the tone knob that allows you to cycle through the different reverbs. Makes it really easy to switch sounds "on the fly." Overall very satisfied. It's a great option for a simple and great sounding reverb.
