This P-Rails pickup set from Seymour Duncan takes the glory of P-90, Strat tones and humbucker sounds and puts them all into one pickup. It's a full-size humbucker that splits to either a full-size P-90 or an Alnico-powered single coil pickup, thanks to the switches mounted on the pickup rings. This combo offers either a full and expansive humbucker tone, a "fat" P-90 sound or even just a classic Strat tone. This set is made for Les Paul-style guitars with curved pickup rings.
