I have a Bareknuckle 58 in my 61P, and a Nordstrand NP4V in my 64P. Both are superb pickups and deliver on “the sound”. I also have an Aguilar AG60P lying around waiting to be put in something, I hear that’s a pretty special pickup too. Was going to put it in my medium scale P, but that currently has a Fender Custom Shop 62 in it and that sounds pretty killer too...
