The Clipping Circuit That Defined “Overdrive”
In 1977, BOSS created an entirely new stompbox category with the OD-1, bringing natural overdrive in 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 more low-end body.
Overdrive Perfection
The SD-1 allows players from beginner to pro to get inspiring sounds right away. Thanks to its natural behavior and the subtle mid boost that’s part of its design, it’s easy to use. It gives your tone a push where it matters most, ensuring your guitar always sits perfectly in the mix with warmth, clarity, and rich presence. Lower drive settings are great for rhythm parts, while higher settings are ideal for fat, singing leads. The SD-1 is also very sensitive to input gain. So, you can dial in different shades of overdrive simply by adjusting your guitar’s volume control.
The One Pedal Every Player Needs
With organic character, plus responsive drive and tone controls, the SD-1 delivers for almost any style of music. Kick on the pedal with your favorite clean or slightly driven amp for a mild-to-moderate overdrive. It’s ideal for everything – from classic rock and gritty blues to pop, country, jazz, and beyond. The SD-1 also shines as a booster for high-gain amps and other drive pedals. It provides mid focus, tight bass, and smooth top end that’s perfectly suited for heavier sounds and solo playing.
