●Asymmetric clipping circuit that defines overdrive

In 1977, BOSS created a new pedal effect category - the Compact Pedal Series.

The first in the series, the OD-1, was introduced as a natural overdrive pedal that overturned conventional concepts.

Asymmetric clipping, which generates rich even-numbered harmonics, delivers the pleasant sound and response of a cranked-up tube amp at any volume, earning high praise from guitarists around the world.

Three years later, this groundbreaking pedal design evolved into the SD-1. By adding a tone knob that can be freely controlled from low to high frequencies, we have arrived at a complete overdrive.

●Supreme overdrive sound

The SD-1 is a pedal that allows all guitarists, from beginners to professionals, to get the ideal overdrive sound.

Its natural response and exquisite mid-boost bring out the charm of the guitar sound to the fullest, making it useful in a variety of situations.

Low gain settings are perfect for backing, and high gain settings are perfect for lead play.

The SD-1 responds sensitively to input levels, so you can create different shades of overdrive sounds just by controlling the guitar's volume.
