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.
Since its original release in the early 80’s the Sonic Distortion has gained a huge cult following among tone connoisseurs, including the likes of guitar legends Scott Henderson and Mike Landau.
Maxon’s current-production reissue captures all the magic of the original with the added benefit of true bypass switching.
The SD-9 provides a smooth distortion that covers a wide range of Gain levels from mild overdrive through pseudo-fuzz. Regardless of the Gain setting, the SD-9 remains articulate and responsive to note dynamics, providing excellent sustain without crossing over into super-compressed Metal territory.
The SD-9’s Tone knob has plenty of top end on tap, yet notes still retain a round, full-bodied tonality with the low end presence usually associated with amp distortion. The pedal’s midrange response is smooth and even – present without seeming spiked.
Since its humble origins to its current place in the pedalboards of the stars, the Maxon Sonic Distortion has proven itself to be a timeless classic that has only improved with age.
