Used BOSS SD1 Super Overdrive Effect Pedal

The used BOSS SD-1 Super Overdrive pedal delivers classic warm overdrive tones with smooth, responsive gain. Featuring simple Level, Tone, and Drive controls, it uses asymmetric clipping for a natural tube-like sound and retains dynamics for expressive playing. This pedal is in good condition, fully functional, and built with BOSS’s legendary durability. Ideal for blues, rock, and more, the SD-1 runs on a 9V battery or standard AC adapter (not included).
