Volume Pot - Darkglass Tone Capsule

[mrblue]

Hello,

I am considering installing a Darkglass Tone Capsule in my SBMM Ray34 Stingray.

After reviewing Darkglass' wiring diagram, it all seems pretty straightforward except for one thing: What impedance value do I want for the volume pot? I cannot use the the stock volume pot since it is attached to the stock preamp PCB. Nor does the pot state the impedance value on it.

Any suggestions for what to use in terms of a volume pot (25K, 250K, 500K, etc.) in conjunction with the stock SBMM pickup?

Thanks.
