Just to give a slightly different perspective than buddy, I think the biggest difference between the PAF Pro and PAF Joe is in pick attack. While the Pro has an immediate reponse with a tight, defined and relatively sharp attack, the Joe has a very dull & swallowed, almost non-existant pick attack, which makes it great for some styles but really bad for others. The dull attack is followed by a relatively brightish tone which makes this pickup very unique - but for some players (including me) very unappealing. Let's put it this way: if you're into speedy, heavily distorted solo playing on the neck pickup and need definition and clarity, stay away from the Joe. But if your focus lies in clean and semi-dirty sounds with a mellow style and unique tone, the Joe is worth a try. Personally, although I'm a big DiMarzio fan, I think the Joe is a swing and a miss! By far.
