With a digital brain and an analog dry signal. the M300 Reverb has six settings, Plate, Spring, Epic, Mod, Room and Pad. Switchable by pushing the Tone knob, you have access at the tip of your finger. With the classics everyone needs like Hall and Spring to the sprawling Plate and the wobble of the Mod setting, hours of soundscaping layout in front of you.
