BOSS SD-1 Super OverDrive – 1995 Vintage Black Label

A classic BOSS overdrive pedal manufactured in Taiwan in 1995, featuring the vintage black bottom label and iconic yellow enclosure.

Known for its warm, mid-focused tone and asymmetric clipping circuit, the SD-1 delivers everything from smooth, natural overdrive to punchy, expressive lead tones.

It also works beautifully as a boost for a tube amplifier or an already overdriven amp.
