Glad to see there’s another Jim Wagner-ite here.
I wouldn’t be sure how to recommend pickups to anyone unless I knew what they were trying to achieve with what style of music.
For instance, I prefer a more focused sound from a Studio than the broad, large swath and swagger of an LP wearing PAFs so there are Jim Wagner Fillmores living in both of my Studio Customs. But then, both SCs have substantial, vintage carve necks and thus plenty of breadth and sustain from the get-go.
