These are the component values for the MXR distortion II as much as I can make out of the schematic. C1 .1uF C10 .022uF C11 .022uF C12 .035uF C13 .035uF C14 .001uF C15 470pF C16 1.0uF C17 .33uF C18 15uF C19 400uF C2 1.0uF C20 10uF C21 10uF C3 .1uF C4 20pF C5 1.0uF C6 .022uF C7 50pF C8 .022uF C9 1.0uF CR1 diode CR2 diode CR3 diode CR4 diode CR5 diode CR6 diode CR7 diode CR8 diode Q1 ZTX109C R1 1K R10 75K R11 300K R12 1M R13 36K R14 3K R15 300K R16 75K R17 100K R18 500K R19 10K R2 1M R20 10K R21 10K R22 50K R23 100K R24 300 ohm R25 100K R26 470K R27 470K R28 1K R29 20K R3 50K R30 100K R31 20K R4 4.7K R5 240K R6 2K R7 36K R8 50K R9 10K U1 TL072 U2 4558 U3 TL072 U4 TL072 VR1 78M15 A1 A1 is a CD4016xx/CD4066xx quad analog switch. Thanks to: Don Syms and CJ Landry for figuring this out! Pins 5 and 6 are control lines and 12 an 13 are also control lines.
"More specifically, pin 5 controls the switch from pin 4 to pin 3, 6 controls 8-9, 12 controls 11-10, and 13 controls 1-2.
Just like a real switch, signal can flow either way thru a switch if it's on (control line HI). You should see the controls tied in pairs with the effect between one pair of switches and the other pair bracketing the bypass path.
I bet you already got that figured out, though. "
