Wah Bias Pot

[Mixa]

Hi everyone,
I'm in the process of modding my wah, Crybaby/Vox type of circuit.
I was wondering which resistor should I replace with a pot in order to have bias control (similar to the Xotic Wah)? Is it the 470/390ohm at Q1 or 470k on Q2?
Thanks!

I'm not familiar with the Xotic, but a trimmer on Q1e is a common mod.
