There was no such thing as a neck or bridge humbucker in the 1950s, but there was a wide range of performance between individual pickups. Some of the old pickups had a lot of wire on the coils, which created more power and a warmer tone. DiMarzio used new technology to duplicate these qualities â without sacrificing the presence and open sound of the best vintage humbuckers â to bring you the PAF Bridge Model, a hotter version of the PAF. Not just for set-neck 24-3/4" scale guitars, this is also an excellent bridge pickup for trem-equipped bolt-ons.
