New, Unused 11108-05-B Seymour Duncan Vintage Blues '59 Humbucker Set Seymour Duncan Never used after purchase! It is a new and unused item! The most important characteristic of the P.A.F., which is the most preferred vintage pickup, is its warm, clear tone and smooth sustain. The SH-1 '59 model is made with the same enamel wire, nickel plating, and balanced coil turns as used by Seth Lover, who invented the humbucker, so it looks and sounds exactly like a '59. It is also impregnated to suppress howling.
