The two cheapest, most common Boss dirt pedals — and the classic beginner question. The DS-1 is a full distortion: bright, mid-forward and gainier. The SD-1 is a Super OverDrive: warmer, lower-gain and voiced to push an amp, with asymmetrical clipping for a more dynamic, amp-like feel.
| Boss DS-1 | Boss SD-1 | |
|---|---|---|
| Type | Distortion — a standalone dirt sound with more gain on tap. | Overdrive — a mid-humped amp-pusher / boost, lower gain. |
| Voice | Bright, cutting, mid-forward and a bit aggressive. | Warmer and smoother, with a Tube-Screamer-style mid-hump. |
| Clipping | Hard clipping — more saturated and compressed. | Asymmetrical clipping — a touch more open and dynamic. |
| Best use | A cheap rock/punk distortion that works into a clean amp. | Tightening and pushing an already-dirty amp, or light breakup. |
| Famous for | Kurt Cobain, Joe Satriani, decades of punk and rock. | Eddie Van Halen, budget boards, an always-on boost. |

The Boss SD-1 is a Super OverDrive: warmer, lower-gain and mid-humped with asymmetrical clipping, voiced to push and tighten an already-dirty amp. Pick the DS-1 to create distortion, the SD-1 to boost and shape an amp.
