Build like a tank… compact to fit on a pedalboard, the Tonebone Hot British is the world’s most compact tube distortion. It is in fact a hybrid that combines the control of a tripple-stage solid-state front end with the warmth and natural even harmonic generation of a 12AX7 tube. The tube is mounted on its side to keep the pedal profile down for easy pedal action and is powered by an external 15VDC supply. Power is internally regulated and filtered to eliminate noise. To further reduce self-noise a unique ground plain circuit topology is employed making the Tonebone classic the quietest pedal in its class. Tonebone is also built tough; 14-gauge steel construction reduces stress on the PC board and a baked enamel finish will keep your Tonebone looking great for years!
