Relay Bypass Board For SD-1
NOTE: BOSS has begun using surface mount components on newer models. Please check to make sure your DS-1 uses through-hole components. This mod will not work on the newer surface mount models.
No more tone suck from your BOSS SD-1 pedals when it is in bypass. Add true-bypass to your SD-1 with our Relay Bypass Board. We provide instructions specific for installing in the SD-1.
