Firebird(TM) pickups have been favorites of players in the know since the model was first released in 1963. While humbucking, they should not be confused with other externally similar-looking mini humbucker(TM) models. Internally, Firebird pickups use two bar magnets around which the coils are wound, giving them a distinctive tone that is somewhat sonically similar to single coils; bright and clear in the highs with the full, tight lows you expect from a humbucker. The Firebird Reissue Plus is wound hotter for a slightly thicker and fuller tone and wax-potted to eliminate microphonic feedback.
