I don't like it. It resembles a 59 in the way it has a boomy low end and scooped mids, but it doesn't sound the same. Duncan makes some good bridge humbuckers, but I'm never satisfied with their neck pickups. Dimarzio makes much better single-sized humbuckers overall, but the YJM and Hot Rails are very good. I didn't care much for the Lil 59. The Duckbucker is way better, but lacks too much output. The Lil JB is bland to me, and less like the JB than the Lil 59 is to the 59. If you are looking for a single-size humbucker for the bridge position, then my favorite is probably the STK-S9. It pairs pretty well with the Hot Stack neck.
