Alnico 4 vs alnico 5 in a P90

[Mikelamury]

Hey guys I was just wondering what the difference an alnico 4 magnet would produce in say a Gibson P90 vs the standard alnico 5 mag? Other than EQ would it have any difference on output? Wanting to find out because I'm contemplating having the custom shop make me a noiseless P90 for my Les Paul junior and I'm wandering what the different magnet would do. I've really liked the few alnico 4 pickups I've tried. Other than that I usually use alnico 5. Thanks for any feedback.

output might be a touch lower but not significantly, eq would be a bigger change

I concur. Should be about the same as what one would expect in a humbucker.
Slightly lower output, tighter low end (and a tighter feel overall), mids less scooped, and highs slightly smoother.

Easy to swap a pair of A4s into your stock P90 for awhile and see firsthand how you like the difference.
