Overview
Not a recent design, the SD-1 has been a gain pedal for generations of players across genres. It is built around an asymmetrical clipping circuit taken from the OD-1, one of the original BOSS compact pedals. The yellow enclosure holds knob controls.
The reason to buy is a proven overdrive voice in a standard compact pedal, with a long manufacturer warranty. The limit is that the listing gives two sets of dimensions and does not name the knobs or the power details.
Who it's for
A player stacking overdrive in front of an amp, or tightening up a clean tone, will recognize the character. Players after extreme distortion or a digital tone set should look elsewhere.
Pros and cons
- Proven overdrive voice
- Analog signal path
- Long manufacturer warranty
- Compact standard format
- Dimensions listed two ways
- Knob functions not described
- Pedal only in the box
- Power details sparse
Performance notes
The asymmetrical clipping stage shapes the gain character that the description calls rich, smooth and tube-like. It is an analog design. The listing does not describe individual knob functions.
