Boss SD-1 Overdrive Effects Pedal (John Kav Modified)
The Boss SD-1 is the longest running overdrive in the Boss range. Produced (and virtually unchanged) for over 20 years, the SD-1 is widely considered to be the asymmetrical clipping counterpart to the Ibanez Tubescreamer. The original Boss overdrive (the OD-1) lacked the frequency range of pedals like the Tubescreamer, so the SD-1 was a redesign of this circuit that included this function.
Modified by John Cav Audio to have a crisper, clearer clipping section.
