The Maxon SD-9 Sonic Distortion pedal offers the best characteristics of transistor and op-amp circuits in one compact unit. It features a unique Low Boost/Hi Boost Tone control that provides more low-end beef than other effect pedals. The Distortion and Output controls can provide up to 55 dB of gain boost. At low gain settings, the SD-9 functions perfectly as a full-frequency overdrive pedal, while higher gain settings turn it into a hand-held monster, providing gut-wrenching grind and singing sustain that can make a clean amp dirty and a dirty amp downright evil.
Technical Specifications:
- Input Impedance: 500K Ohms
- Input Jack: 1/4 inch standard phone jack
- Output Impedance: 10K Ohms
- Output Jack: 1/4 inch standard phone jack
- Maximum Output Level: 0 dBm

The pedal is highly versatile, offering a smooth distortion that covers a wide range of gain levels from mild overdrive through pseudo-fuzz. It is known for its ability to provide an immense range of distorted tones, from punchy overdrive to blistering fuzz, all with full-frequency response.
The Maxon SD-9 Sonic Distortion pedal has been praised for its clarity, punch, and ability to retain low bass, making it equally great on both neck and bridge pickups, whether they're humbucking or single coil.
