Producing warm and natural distortion of an overdriven tube amp, the BOSS SD-1 does not lose any sonic nuance of the user's picking technique. The circuitry of the BOSS SD-1 produces a genuine and authentic overdrive effect, though with the simple tweak of the tone control dial, add some dirty grit or a more rounded tone to the music.

Incredibly user-friendly, the SD-1 recreates that classic overdriven sound that is synonymous with the electric blues and rock music that remains so influential in contemporary music today.

Features:

• Compact overdrive pedal with warm, smooth overdriven sounds
• Unique asymmetric overdrive circuitry for a classic, natural tube amp growl
• Tone control provides precise adjustment of drive sound
