An excellent option for recording, small gigs, or general home practice with the master volume. The Hatt Amps Mean 15 is a 15-watt hand-wired tube amp that is built right here in Lansing, Michigan. 2 12AX7 tubes, 2 EL84, and a GZ34 rectifier tube deliver a full-bodied tone through a Warehouse ET65 speaker in a solid pine cabinet. The sound is full and rich, without the distortion that comes to mind when you think of 15-watt amps.
