Description

BOSS SD-1 Limited 50th Anniversary Edition – A Collector’s Tribute to 50 Years of BOSS Innovation

The BOSS SD-1 Super Overdrive has been a go-to guitar pedal for players across all genres since its release in 1981. Built around BOSS’s revolutionary asymmetrical clipping circuit, it delivers smooth, natural overdrive with tube-like warmth and responsiveness.

Whether used for a subtle boost or full-bodied drive, the SD-1 enhances clarity and ensures your guitar cuts through the mix with ease.

Versatile Overdrive for Any Setup

Ideal for use with clean and slightly driven amps, the SD-1 provides mild-to-moderate overdrive that works well for everything from classic rock and blues to country and pop. It also tightens high-gain tones and stacks well with boost, overdrive, and distortion pedals, making it a versatile addition to any setup.

Built to Perform

Designed with BOSS’s industry-leading reliability, the SD-1 is housed in a durable stompbox with intuitive controls for drive, tone, and level. Its responsive dynamics allow for expressive playing, letting you shape your overdrive simply by adjusting your guitar’s volume. Backed by a five-year BOSS warranty, this pedal is built to last.

50th Anniversary Limited Edition Model

Celebrating five decades of BOSS craftsmanship, this 50th Anniversary Edition faithfully preserves the legendary tone and circuitry of the original model while introducing a sleek metallic finish, gold-capped knobs, and commemorative anniversary badging. This special model is part of a very limited run, so once stock is gone - it's gone forever!
