Never had a PRS with Miras (per say), but I know they're just uncovered 245's and I had a set of 245's in my Bernie and they were great, but I did swap them out for, ironically, an early set of 5708's. Nothing wrong IMO with Miras, just not for some people.
There was a time PRS was doing a pickup exchange or something like that. Theres some KL33 floating out there with 5708 stock(ish).
When I was in the process of buying my KL, I was conversing back and forth with GC, yep GC and the salesperson couldnt tell me what pickups it had. I thought maybe someone had swapped the pickups or did the PRS exchange, but the hang tag stated 5708s. I did not know any KL's that came stock with 5708s. Sergio urged me to grab it and so I did.
When I contacted PRS and shared a shot of the hang tag, Shawn stated "it was one of those instances where Paul made a flying change and we didn’t bother making a new MODCAT for the guitar, everyone just knew that the pickup specs had changed. You've got one of a limited few with that change. In early 2009, the 57/08’s still had plain covers. We didn’t start etching them until later."
Apologies
@Greywolf didn't mean to hijack your NGD thread.
Looking forward to hearing what you think of the KL!
