Crafted with a diehard metal enclosure, four-knob layout with controls for volume, voice, tone, and gain all within one of the most compact enclosures in production, the Mooer Rumble Drive Overdrive brings a big wallop of sound in a small punch. Highly responsive, the gain and voice control allowing for contour take the drive from the organic warmth of a blues rig all the way to screaming mid-range green for gobs of attack. Perfect as a compliment to your existing boost or overdrive, the Rumble Drive also has no trouble standing on its own and delivering.
