From the vendor
The Boss factory schematic of the DS-2 Turbo Distortion, part of a look at John Frusciante's Californication-era pedalboard. The post describes it as a complicated design built from discrete op-amp stages with a switchable boost and mid-peaking filter (the Turbo mode). Since no project files existed for it, the author suggests building a Marshall Shredmaster instead.

- Two resistors are both labeled R1 on the drawing: R1 10K on the Turbo switch (VR board) and R1 1M on the FET-switching flip-flop; both are listed as drawn.
- The 470p capacitor beside R22 in the flip-flop reads C5, the same as the 220p C5 below it; it is probably C6 and is listed as C6.
- The 100K resistor to +4V at Q3's drain is printed indistinctly (R35 or R36); listed as R36, since R35 150K is at Q13.
