Re: Difference between coil tapping and actual single coils?
I've always split my humbuckers, always interested in how they sound. Most have a brittleness that is just not cool when split. Some work though. Here are some examples, in mahogany 24 3/4 and 25-inch scale guitars:
BRIDGE
Duncan Custom Custom: best of the lot: unsplit, the Custom is fairly hot but retains some of the PAF vibe, similar cry under OD, turned down it approaches the '59 in character - not as sweet as the '59 but then not as shrill either. SPlit it is pretty darned close to the Alnico2 pro single in my Strat - decent bottom end, fairly clean and sweet. If you PM me I'll record a little demo for you.
Tone Zone: Not at all vintage sounding though sweet if you go gentle on it, the TZ is very sensitive to attack. Split it is still big, makes a heck of a singlecoil! Not very stratlike, more like a p90
Duncan JB - not at all vintage sounding, as a full bucker can be sweet but can also be annoying. Split though it is a really nice pickup, good mids, not as much bottom as the TZ. Would not be mistaken for a strat but a usable sound nonetheless and at ~8K a lot of power for a split HB.
Neck
Jazz - the best neck pup IMHO, clean and sweet and round as a bucker, split has a nice woody tone, not as full as a strat neck pup (decent low end but a bit thin in the middle), but eminently usable.
PAF Pro
the Pro IMHO is a bit dark for a neck pickup -- some will call it smooth and it does have a sweet top end. It works well with a lot of gain in a tone stack that dumps low-end. Split it has a brittle quality that is not real attractive
