I recently grabbed a really nice used Gibson J-45 (rosewood). I need to have some setup work done on it, and I'd really like to replace the pickup system with something else. The stock UST sounds very "quacky" to me, and I believe there may be better options available for this guitar. I'll be running the guitar through an LR Baggs Venue pedal.
I do have another guitar (a OO size) with a K&K Pure Mini, which sounds pretty nice, but I'd thought I'd check here to see if other J-45 owners have swapped out their stock pups and what they've found works well.
