Vintage Blues Set: While these vintage style coils give the 59 Model humbuckers an airy quality that keeps them planted firmly in the P.A.F. family, the alnico 5 bar magnet, and vacuum wax potting have been added to compensate for lighter guitar strings and louder amplifiers than were ever used in the 50s. The result is a pickup with tons of old-school tonal character, but with a brighter top end, and a more compressed sound. The 59s are great for all types of rock and blues. In addition to the alnico 5 magnet and wax potting, we hand build the 59 Model with a variety of traditional vintage treatments, such as 42AWG plain enamel mag wire, long legged nickel silver bottom plate, vintage single-conductor braided push-back lead wire, and no logo.
