Weed BOSS DS-1 Mod Double Switch - 楽器堂オンラインショップ,Boss DS-1 MIJ Vintage Tri-Gain Plus Mod,Opened up my DS-1 to do a small solder-less mod, only to find this PCB. Yes, this is the entire circuit. The SD-1 I bought the same day has the normal size,Boss DS-1 I modded with a tone bypass switch. The change is a bit subtle, seems a tad more open with the tone stack bypassed with a bit more mids. Not as prominent as a tone bypass in an old Big Muff pedal. : r/diypedals,Boss DS-1 Mod Kit( August 2022) - fromelelectronics
