For example, a boomy neck PU with a stock A5; I'd consider an A3 to keep treble while reducing low end and output, or an A4 that would add some mids and take off a little treble. In an A2 neck PU, if it's too dark, I'd try an A4, A3. or A5 (in order of brightness).
For a bright/thin/scooped A5 bridge PU, I've used:
-Roughcast A5 (for a smoother, less harsh high-end)
-A4 for moderate warmth
-Roughcast A4 for a smoother high-end
-A8 for mids and high output, an 'alnico meets ceramic' sound
-UOA5 for A2-type dynamics but with a tighter low-end, and a bit more treble and output
-A2 for dynamics and a rounded high-end
-Roughcast A2 for an smoother, fuller high-end
A low output magnet like an A2, in an overwound PU like a JB or Custom, will still make for a hot PU. What changes is the warmth and organic feel the A2 brings to the party. A2's are very good in JB's. I also really like UOA5's in Customs. Everything just seems to come together. You get the best qualities of PU and magnet.
I usually use A8's in hotter bridge PU's, never in the neck, although a few guys do. Some guys use A8's in bridge PAF's too, like PGB's. In (low output) PAF's I like to keep that vintage feel and use polished A2, A3, A4 and A5 in the necks, and in the bridges use roughcast A2, RC A3, RC A4, RC A5, and UOA5. But that's just me. Some guys like roughcast magnets in the neck slot. There's no rules on what PU's, magnets, and ohms match up; it's all a matter of taste. What magent will it take to get your EQ where you want it? Everything's on the table for consideration.
