The Electro-Harmonix Hellmaster is a high-gain distortion pedal from EHX delivering extreme saturation suited to hard rock and heavy metal applications. The Hellmaster provides aggressive, high-gain character with a dense, compressed distortion voice and sufficient gain for modern metal rhythm and lead playing. As an EHX product in the heavier end of their drive lineup, it targets players who need a dedicated high-saturation distortion suitable for heavier genres without the boutique pricing of more specialized alternatives.
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.
