I think p90s traditionally go with 500k and .022 caps, like all gibson products. There's also no reason not to change them, depending on what works for you. No need to copy what Gibson and Fender did all those years ago. I've got 500k pots in my telecaster and it sounds great.
Vintage vibe sells a p90 in HB clothes too, and Fralin might as well.
