The Clipping Circuit That Defined “Overdrive”

In 1977, BOSS created an entirely new stompbox category with the OD-1, bringing natural overdrive in the pedal form to guitarists for the very first time. Producing a signal rich in even-order harmonics, its unique asymmetric clipping circuit replicated the pleasing sound and feel of a driven tube amp—but at controllable volume levels. Four years later, this breakthrough design evolved into the more versatile SD-1, which added an active tone control for shaping the treble response and subtle enhancements for a more low-end body.

 

Overdrive Perfection

The SD-1 delivers inspiring tones for players of all levels with its natural response and subtle mid boost. It enhances your tone where it matters, ensuring warmth, clarity, and presence in the mix. Lower drive settings work well for rhythm, while higher settings create fat, singing leads. The SD-1 also responds to input gain, allowing different overdrive shades by adjusting your guitar's volume.

 

The One Pedal Every Player Needs

With its organic character and responsive drive and tone controls, the SD-1 delivers the right sound for just about any style of music. Kick on the pedal with a clean or slightly driven amp for mild-to-moderate overdrive. It’s perfect for classic rock and gritty blues. You can also use it for pop, country, jazz, and more. The SD-1 works great as a booster for high-gain amps and drive pedals. It enhances mid-focus and delivers a tight bass response. The smooth top end makes it perfect for heavier sounds and solo playing.
