shows an upgrade for an Epiphone Les Paul using Seymour Duncan P-rail pickups plus switchable tone pots.

The circuit diagram for this mod is here

I have an Epiphone Firebird I want to upgrade this way. I think I have found the pickups here

My question is, where can I purchase the Tone pots with DPDT switches? Does Seymour Duncan sell them?

Thanks,
Don
