Mo Joe is essentially a 9k PAF with two rows of screws, should work well in that application, but you'll still need to lower the PAF pro probably, and raise the pole pieces. PAF Pro is fairly hot for a neck position.
Mo Joe is a pickup that doesn't get much attention, but it's very much in the DiMarzio PAF family. 36th bridge, Mo Joe, DiMeola Bridge can all be considered variations on a flavor, kind of all chocolate but the difference is how much coacoa is in your chocolate. PAF Master is a little farther outside that group, but not much farther.
