I have one as well - don’t know how many were made, other than to say it was a somewhat limited number, probably in the low hundreds, just based on how many I’ve seen pop up in the wild - I watched them for a while when I was looking for one.
The pickups are SD ceramics, it’s kind of an oddball set that PRS specs by using one of their hot neck pickups as a bridge pickup, or something like that - it’s the same set that came in most of their other P90 guitars until they changed over to the Antiquities on the 594’s.
Another fun fact, the neck is somewhat of a rarity amongst PRS guitars, it has the same carve that became the standard on the S2’s, but in a 24.5” scale. The Mira X also had a 24.5” scale, but was a significantly bigger neck shape (wide/fat).
I found the stock pickups mildly overbearing in the low mids, and changed mine out for the standard P90 set from SD. I could see myself even going to a set of the Lollar alnico pole P90’s, or a set of soapbar mount TV Jones pickups, to add even more chime. But that just depends on how I want to use it, the current P90’s are great for ballsy rock tones.
