The BOSS SD-1 Super Overdrive Pedal doesn't muddle your playing style with excessive or over-the-top distortion - instead, it accentuates it with a rich, authentic sound akin to warm, classic tube driven overdrive. It features an intuitive three-control setup: Level, Drive, and Tone - and that's really all you need to get a great sound from it. Use it for mild to hard overdrive, or just as a signal booster by rolling the Drive back, the BOSS SD-1 Super Overdrive Pedal is a great option for guitarists of any style, especially rock and blues.
