Though small in size, its unique 2-stage preamp has a massive tonal range using just Volume, Tone, and Gain controls. When driven, it's got almost as much gain as most 4-stage lead channels. Mid-gain settings deliver masses of vintage British character, with sparkling cleans coming from lower gain levels. Switches from 15W to 7W watts for studio use. Loaded with a 12" Celestion G12H-30 70th Anniversary speaker.
