Relay Bypass Board For SD-1

This item is currently out of stock.

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.
