Re: Pots on a HSS Strat: 250k or 500k?
Just my humble opinion:
I'd try 500k for the tone pot, but use a .022 cap (or .033 at most). A .047 cap will make the neck pup way too dark in most cases, even with the tone pot at 10.
Remember, a higher value tone cap value means that the frequency cutoff point for the tone control goes down in terms of frequency. A .047 cap will start grounding out your upper mids, not just treble.
For the volume, try a 250k or 300k pot. If it's too dark at full volume (unlikely in a Strat), you can always add a resistor between ground and the outside leg of the volume pot (i.e. 250k + 50k = 300k, etc.). After all, how often do you actually turn the volume all the way down?
A treble bleed on the volume pot is also a good idea to retain the high end as you roll the volume off. This will also make the 250k volume more viable working with both single coils and a humbucker. My personal preference for single coil pups is the Kinman mod with a 130k resistor in series with a .0012 cap, but please do a search here for "treble bleed". There are more opinions on the subject of which treble bleed works best than there are guitars in the world.
Hope this helps,
