Launched in 1981, the SD-1 refined the OD-1 circuit, becoming a favorite for its smooth, tube-like drive and asymmetrical clipping.
Since its release in 1981, the workhorse SD-1 Super Overdrive has been the core gain pedal for generations of players across every musical genre. Based around the revolutionary asymmetrical clipping circuit from the OD-1 Overdrive—one of the three original BOSS compact pedals from 1977—the SD-1 delivers rich, smooth, and highly musical overdrive tones that continue to inspire guitarists everywhere.
Guitarists find the Boss SD-1 to be a reliable and versatile overdrive pedal. Users appreciate its ability to work well with different amplifiers and guitars, and many use it as a boost or to tighten up their sound. Some guitarists stack it with other pedals, like the [electro-harmonix Soul Food], to create unique tones, and it is often seen as a 'go-to' pedal. While some users have compared it to boutique pedals, many keep it on their boards for its classic sound, and AC/DC tones.
