I have a PRS SE Custom 24 with a Floyd Rose that I need new pickups for. The HFS in the bridge is good, but not great. It's too one-dimensional. The Vintage Bass in the neck is pure mud. I really like the tone of the 57 and 66, but I would prefer passive pickups to split the coils. Are there any good passive substitutes? I'm thinking maybe a passive EMG set or Alnico Black Hawks. I'd like to get Seymour Duncans if they get reasonably close, but I haven't played a set that does. That's not to say that it doesn't exist, though. Any suggestions would be greatly appreciated!
