Boss SD-1 Super Overdrive Pedal Taiwan 1989

That's how a vintage overdrive pedal should look, right? The Boss SD-1 is the perfect little catalyst for your Strat and Marshall stack to really push things into super smooth, singing overdrive. This one just turned 30 and has a few marks to show for it, but hey, it's got experience now!
