Well no response from mods on sticky so this may be forever lost, but:
Neck humbuckers, general mod to remove mud (note this is not nearly as noticeable with air buckers, so check for that before doing it) Remove 3 poles under the bass string on the neck side coil. If slug/screw config, I generally put the screws toward the bridge and knock out 3 slugs. Pushing them out is not difficult; they'll slide right out of the bobbin with some pressure, and go right back in later. Result: Major reduction in mud on the low strings. You end up with something approaching the tightness of a single on low string low notes, with the fatness of the humbucker on the high strings. NOTE: Adjust the poles on the other coil so that string balance is maintained. The D and high E poles need the most raising, the low E not much at all, A and B somewhere in between.
Humbucker from Hell, change magnet to ceramic: This requires removing one spacer as the stock magnet is a special size, thinner side to side. Not hard surgery. Result: Stronger output, more articulation in the neck. Also benefits at that point from removing 3 poles as noted above.
DP223 36th Anniv Bridge: Change magnet to A2. This is my current (by far) favorite pickup for the bridge of a strat with 250k volume pot. Articulate sound with nicely vocal mids, no mud, removes the harsh high end from the stock A5 version. I like this better than any bridge PAF, including the oft drooled over Tom Holmes. Splits nicely with the middle pickup (I always leave the bridge coil active, if you're using Area middle this requires flipping magnet polarity on the 223, but since the mag is changing anyway, no extra work).
Super 2 in the neck: Remove all poles from neck side coil. Result: Sounds like a big, loud single coil. Loud enough to easily keep up with a mid range bucker in the bridge (Air Zone, AT-1, etc.). Tight, bright, but with output no single can cop.
More to come......
