Re: JB in the bridge, Jazz in the neck, and what noiseless singlecoil in the middle?
If you're looking at splitting the neck and bridge, is it worth instead using a normal single coil, so when the hums are split it'll still be hum cancelling in 2 and 4? Otherwise, as far as hum cancelling, I've got what I thought were really great tones out of a Classic Stack Plus (STK-4, I believe), and I would think the classic is the way to go, output wise; any hotter and it wouldn't mix well with the jazz, in split or series configurations.
