Again I recommend, as Nelskie and Spud pointed out to you, on the Seymour Duncan Pearly Gates bridge and the Duncan '59 on the neck. As per your musical interest in classic rock and blues this pup combination will please you tremendously I believe. While I do not have the '59 in the neck on my Les Paul Studio I know Nelskie's recommendation is right on the money. I do have the Duncan Pearly Gates bridge pup and for any Les Paul I would think it a requirement! My neck pickup on the Gibby is the stock Gibson PAF pickup which they installed on Les Paul Studios during the mid '80s. That pickup also produces tasty tones.
