Even though I have one in-hand, I don't know much about them. My impressions are:
1. Not super high output, but not super low either. Perfect setup for using the guitar to control gain tone.
2. The neck and bridge in parallel single coil mode (position 4) is far and away the best single coil tone out of any PRS I've ever heard. Really different than on other split coil PRS in any configuration...
3. There may be something special going on with the wiring with these in comparison with other CU24s, but tone response changes as a function of volume knob changes is absolutely perfect. Interplay with the tone knob is good too, but the really good part is how tone changes with volume knob changes.
4. Humbucker modes (1,3,5) are more classic PAF than either my DGT pickups, 57/08s or 59/09s. That may be good or bad depending on what you're going for, but it's good for me.
I don't know enough about anything to separate what I'm hearing as a function of pickups versus wiring versus the actual guitar, but one way or the other, they're more than just someplace in the middle of 57/08s and 59/09s
