The Seymour Duncan Antiquity Retrospec'd P90 Dog-Ear bridge pickup uses two specially calibrated Alnico II bar magnets, and a custom coil wind to deliver the gritty, vintage correct growl of a late 50s ES-330 bridge pickup. Chords have a gritty, honky midrange, and single notes are nice and articulate without sounding harsh. The Antiquity Retrospec'd series offers all the beloved Antiquity tone of yesteryear in a brand new, cosmetically non-aged look.
