We designed the Fat Daddy for two reasons: first, to give a higher output Neck and reverse-polarity/reverse-wound Middle to use with our Shredder Bridge pickup, and second, to give a fuller, fatter Bridge pickup for our Tone Daddy pickups. The Fat Daddy is 9.9k and has Alnico III magnets for clearer Fat tone.

We highly recommend the RS Vintage Strat Upgrade Kits; you can view them here:
