I remember playing a few back when they first came out. Gorgeous looking things, but, despite the promises, the pickups couldn’t really nail P, J or MM in a way that was satisfying or particularly authentic. They had their own great sound, but the big selling point - that they could ape all those other sounds - just didn’t ring true for me. YMMV, but I wasn’t convinced.
To get an authentic MM sound, you need the active electronics to work on specific frequencies, which are different to the frequencies you’d use on an active Jazz for that Marcus tone, or the frequencies you’d want to use to bring the bark out of a P pickup (all mids, and the basses had no midrange control).
