Few pedals have earned the legacy of the BOSS SD-1, and this limited 50th Anniversary edition—SD-1-B50A—pays tribute in glorious style. Same circuit, same legendary tone, but wrapped in a shimmering metallic finish and dressed to the nines with gold-capped knobs, silver hardware, and a commemorative badge that marks half a century of BOSS brilliance.

Inside, it's still the classic SD-1—a warm, smooth overdrive that retains your guitar's clarity and dynamic response. Its asymmetrical clipping circuit is what sets it apart from the pack, mimicking the creamy, natural breakup of a valve amp being pushed just right. Whether you’re boosting a clean channel or stacking it into distortion, it delivers that gritty, mid-focused bark that slices through any mix without sounding harsh.

But this isn’t just about tone—it’s about history. The 50th Anniversary model isn’t some off-the-shelf reissue. It’s been given a full makeover, with a metallic grey enclosure, gold-detailed knobs, a unique silver thumb screw, and most importantly, a limited-run serial number engraved on each unit. Proper collector’s piece, this one.

This particular pre-owned SD-1-B50A has been well cared for and is in top working condition—fully tested, clean, and ready to roar. Whether you're buying it for the tone, the looks, or both, it’s a pedal that earns its spot on any board.

You don’t just buy this pedal—you join a little piece of pedalboard history. If this Pre-Owned SD-1-B50A sounds like it belongs on your rig, give us a shout here at Musicmaker and we’ll get it sorted. She won’t hang around for long.
