Legendary Super Overdrive SoundSince its release in 1981, the iconic BOSS SD-1 Super Overdrive has been a staple gain pedal for generations of players across every style of music. Developed around the revolutionary asymmetrical clipping circuit from the OD-1 Overdrive, which was one of the three original BOSS compact pedals from 1977, the SD-1 provides rich, smooth, and sonically rich overdrive tones that continue to influence guitarists everywhere.

In 1977, BOSS created a completely new stomp box 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 manageable volume levels. After four years, 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.

At A Glance • Unique asymmetrical clipping circuit produces tube-like overdrive characteristics
• Also works great for bringing tightness and definition to high-gain amp tones
• Mild-to-moderate drive tones with focused midrange and tight low end
• Genre-defining BOSS overdrive sound

Overdrive Perfection

Inspiring TonesThe SD-1 lets players from beginner to pro get inspiring sounds instantly, due to its natural behavior and the subtle mid boost that's part of its design. Your tone gets an extra push where it makes a difference, so 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 huge, singing leads. The SD-1 is also very reactive to input gain, letting you dial in different shades of overdrive just by adjusting your guitar's volume control.

The One Pedal Every Player Needs

Works For Any StyleWith its organic character and responsive drive and tone controls, the SD-1 gives you the right sound for just about any style of music. Engage the pedal with your favorite clean or slightly driven amp for mild-to-moderate overdrive that’s ideal for everything from classic rock and gritty blues to pop, country, jazz, and beyond.

The SD-1 also works great as a booster for high-gain amps and other drive pedals, providing mid focus, tight bass, and clear top end that works perfectly for heavier sounds and solo playing.
