The BOSS SUPER OverDrive SD-1 Pedal brings natural tube amp overdrive in a stompbox. Its asymmetrical clipping circuit produces harmonically rich overdrive like a driven tube amp at any volume. An active tone control lets you shape the treble response for your desired tone. The SD-1 is also very sensitive to input gain, allowing different shades of overdrive by adjusting your guitar's volume control.

A Clipping Circuit That Started It All

In 1977, BOSS created the first overdrive stompbox, the OD-1, bringing overdrive effects to guitarists. Four years later, BOSS improved upon this design with the more versatile SD-1. Its asymmetrical clipping circuit provides authentic tube amp overdrive with subtle mid boost for presence and clarity. The SD-1 allows you to get great tones right away, from clean boost to saturated overdrive.

A Pedal for Every Player

With responsive drive and tone controls, the SD-1 delivers the right sound for any style. Use it with a clean or slightly overdriven amp for classic rock and blues overdrive. It also works as a booster for high-gain amps, providing tight bass, smooth highs and mid focus ideal for heavier music and solos. The SD-1's versatility makes it a pedal every guitarist needs.

Dial in Your Overdrive

The SD-1 gives you overdrive like a tube amp without losing the nuances of your technique. Its Level, Drive and Tone controls make it easy to go from mild to saturated overdrive. Lower Drive settings are great for rhythm, while higher settings produce singing leads. The SD-1 is also sensitive to input gain, letting you adjust your guitar's volume control for different overdrive shades.
