I've written here about my new Les Paul and I'm already planning some upgrades. I have a set of Gibson Classic '57s I want to install with the Jimmy Page wiring and I can't find anyone who sells quality 500K push-pull linear taper tone pots. I've found some Bourne imports but want better quality with US pot shafts. If you've not run into it, JP wiring uses four push-pull pots for coil splitting, series-parallel and in-out phase switching. I've bought some CTS audio taper pots for the volume controls but am having trouble finding the linear taper pots for the tone pots.
