I have an f-100 series 1, I am wondering how much it is worth. I did replace the pickups with seymour duncan's years ago but still have the original pick ups. I am missing the back plate and whammy bar, but have the original case. Do I have a gem here or just an avaerage guitar. I am thinking of selling it because I don't play it and it weighs alot and hurts my shoulder. Any help would be appreciated. I'd consider trading for a lightweight hallow body... Thanks Keith
