SD-1 Dumble Mod Pack




Add to wishlist

NOTE:  BOSS has begun using surface mount components on newer models.  Please check to make sure your SD-1 uses through-hole components.  This mod will not work on the newer surface mount models.

This one is one of our favorite SD-1 mods.  First of all the silicon clipping diodes are replaced with a MOSFET and Germanium diode clipping pair.  This gives it a richer saturation and longer sustain without over compressing.  Next, the frequency response is leveled out, and given a heavy dose of tight lows.  Then we give it a lot more gain without making it sound fuzzy.  All the aluminum electrolytic caps in the signal path are replaced with metal film caps for improved sound quality and clarity.  And lastly, it's louder.  The drive knob can clean up much better and it still has plenty of boost on tap.  Comes with your choice of LED color.  Desolder braid not included.
