I just put in a Lollar Standard wound P pickup in my Duck Dunn. Too early to make an informed comparison. I'm looking forward to hearing it with the band !
I've gone through phases of enjoying other P pickups but the Lollars are perfect to me. Have a set in each of my p basses.
I tried several P pickups among the Lollar. To me it is too clean, kind of sterile. My favorites were a real '65, SPB 1, Lundgren, Bare Knuckle. And some of my self wound PUs.
