I am putting some new pots into the guitar I'm upgrading, it's a stratocaster copy.

I'm upgrading it with a Seymour Duncan JB, and I'm going to coil tap it, so what would the value of the pot. be that I need? Would it be 500K? I know that to be a push pull, it has to be DPDT, or something.

I am also looking to replace the 2 tone controls. What values would they be? Would they need to be different because one tone would be for the humbucker, or what?

Help is very much appreciated.
I figure 500k for the volume and the 1st tone, then 250k for the 2nd tone so I'll have a warmer, more vintage neck/middle sound. Does this sound like it would work?
