The "Black sheep" of the 9-Series,the Sonic Distortion offers the best characteristics of transistor and op-amp circuits in one compact unit.

The SD-9's unique Low Boost/High Boost Tone control offers more low-end beef than other pedals, while its Distortion and Output controls can provide up to 55dB of gain boost.

At low gain settings the SD-9 functions perfectly as a full-frequency overdrive.

Higher gain settings turn it into a hand-held monster; providing gut-wrenching grind and singing sustain that will make a clean amp dirty and a dirty amp downright evil.
