SEYMOUR DUNCAN SH-PG1b & SH-PG1n Pearly Gates The Pearly Gates were designed based on the original pickups in Billy Gibbons' 1959 Les Paul of ZZ Top, which were noted to have slightly higher output than many P.A.F. pickups. Using Alnico 2 magnets, the pickups deliver a crispy tone with emphasized mid-range, combining both roughness and sweetness. This is a set with a bridge reverse zebra and a neck zebra. There are no issues with the operation. Screws and springs are included.
