The MXR M300 Reverb pedal offers six meticulously crafted reverbs in one pedal, featuring audiophile quality analog and digital audio paths. The pedal's dry path is 100% analog, providing a studio-grade low noise floor. The pedal's design includes 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™. The reverb styles include Plate, Spring, Epic, Mod, Room, and Pad, each offering a unique sonic character.
The MXR M300 Reverb pedal features a hi-fi analog and digital audio path, with a true relay bypass and trails bypass mode that allows the effect to ring out after turning the pedal off. It also includes an expression pedal jack for foot control of all knob settings, and stereo In/Out capability when using TRS cables. The pedal can be powered by the included Dunlop ECB003 9-volt adapter or the Iso-Brick™ and Mini Iso-Brick™ power supplies (not included).
