I have owned all three pickups, 57's (in Les Paul), 59 (in strat and Joe Pass), and Seths (Epi Sheraton). The Seths are my favorite out of the three. The 57's are great for warm, classic jazz. The Seths can get that, as well as articulate jazz leads (not wax potted.) These pickups make the tone control usable. The 59's are somewhat middy, and sounded decent but terrible in a strat style.
The Sheraton with Seths is one of my favs. I tried other pickups in there but nothing compares to them. Check the bracing on the guitar as well. My Pass howled unbelievably with some hotter pickups.
