The Ceriatone Joyful Music JM20 amp, is a 20 watt amp is based on the tone of the legendary John Mayer. This is the amp that defines Mayer's tone better than any we've heard out there. This amp does includes a state of the art all tube driven, spring reverb circuit.
Note: The JM 20 watt version is NOT a lunchbox sized amp. It is a full sized amp, but only 20 watts.
