Ok, I found some local dealers for the unbuckers, so that should be okay. Actually, I suppose I could drive down to Richmond if they sell them there, but that's a little farther than some other dealers. I'm asking them exactly which pickups these are, but they come with some caps, though they say those are for the tone knobs:

So, 500k for the volume knobs... are you saying I should also do 500k audio for the tone knobs? I would think I'd want linear for that, though I have no idea what resistance I would want them to be. Is there any advantage or disadvantage to having those covers on the pickups?
Thanks for the help so far

I'm pretty clueless...
Edit: The ones they have in stock are the regular humbuckers, so I'd have to special order Unbuckers either way. How do they compare to the standard humbuckers? The web site says the primary advantage of the unbuckers is for coil tapping, which I would not be doing, but I imagine there has to be another benefit.
