Base pedal: Maxon SD-9 Sonic Distortion
Compared to the Maxon SD-9 Sonic Distortion, a mid-1980s Japanese circuit beloved for its tight, harmonically rich distortion and natural-sounding sustain. The SD-9 sits between a pushed overdrive and a full distortion, with a compressed attack that works beautifully for leads and rhythm alike — and original units command strong prices on the vintage market.
