In the late 70s, Seymour Duncan was well known as the go-to guy for the tone-chasers that needed something custom. Sometime in ‘78 he was given a P.A.F. with the instructions to rewind it and make it more sensitive to natural and artificial harmonics. In other words, give it the Duncan “hot wind” with a little extra. The Seymour Duncan ‘78 is loaded with an Alnico 2 magnet, wound to the exact same hot specs as that original P.A.F. rewind. The magnet and output combination lend themselves to a warm crunch with biting leads and overtone laden tapped runs.
