I've had both PAF Pros and PAF Joes in my PGMs. I no longer have the PAF Pros. One of my PGMs has a PAF Joe in the
neck position and I love it compared to the PAF Pro. When I play with the guitar's volume wide open with a
distorted tone, it's a smooth, fat yet articulated tone. The tone is tubular just as Dimarzio claims. When I turn the guitar's volume down with a distorted tone, the guitar tone becomes more single-coil coil like. It's really quite amazing.
I know a lot of folks like the PAF Pro but for me, I've never really liked it. It's always been an in between kind of tone (bright but not bright enough and fat but not fat enough). The PAF Joe is much more to my like and is one of my 2 favorite neck pickups though I'm starting to feel like it is my favorite period.
