The black sheep of Maxon's 9-Series, the Sonic Distortion offers a convincing balance between transistor and op-amp characteristics. The unique Low Boost/Hi Boost tone control offers plenty of beef while the output and distortion knobs dish out up to 55dB of vicious gain boost. At low-gain settings, the SD-9 functions perfectly as a full-frequency overdrive. Crank the gain and get gut-wrenching grind and singing sustain that'll turn a clean amp dirty and a dirty amp downright evil. Features true bypass, and die-cast zinc case.
