Needing help with adding more tone options to a pedal. SD9 w MGV tone controls

[geraldwp]

Hey everyone I am trying to build a schematic around this idea. I want to build an Ibanez SD9 with Marshall Guv'nor Tone Controls.

The schematics & layouts I will be using are from JD at General Guitar Gadgets.

I know that the tone control section for the SD9 starts at R10, but how do i need to go about adding the MGV tone controls to this circuit.

Thanks for any help.

Gerald
