Re: HSS set that will balance well.
For the Hybrid, 250k would make it darker. I think HSS (with master controls) sound better with 500k on everything. Especially if the SS pickups are either stacks or Little Humbuckers.
I like your suggestion of the stks7 in neck and the stks4 in the middle. Still set on the custom/59 hybrid. To run a humbucker on a 250k pot, how would that effect it? Make it darker/brighter?
