Maxon SD-9 Sonic Distortion
Maxon · pedal
The Maxon SD-9 Sonic Distortion is an iconic vintage Japanese distortion pedal from Maxon, known for its unique, raw, and slightly acidic distortion character that crosses the line between distortion and fuzz. The SD-9 was used by Kurt Cobain of Nirvana as his primary distortion pedal, and its distinctive, slightly ragged harmonic character became associated with the Nevermind-era grunge sound. The circuit produces aggressive, cutting, raw distortion with a character that no other distortion fully replicates.
