The SH-55 was designed jointly by Seymour and humbucker inventor Seth Lover. Just like the original 1955 P.A.F.s, the SH-55 utilizes a nickel silver bottom plate, butyrate plastic bobbins; plain enamel wire, an Alnico bar magnet, a wooden spacer, and black paper tape. The SH-55 uses a nickel silver cover instead of brass, which magnetically eliminates too much of the pickup’s natural high-end tone. To be completely true to the original design and tone, the pickup is not wax potted. The tone is vintage P.A.F. The neck pickup will warm up even the coldest guitar. And the unpotted covers give the bridge pickup just enough boldness to break up early and really cut. Single conductor cable standard.
