I installed this pickup in a too bright Epiphone Slash Les Paul. The guitar sounded good but a bit boxy and too bright for a Les Paul for my taste.
The update made it sound huge, fat & raw. Perfectly suited for heavy rock and metal (Guns, Alter Bridge, Black Stone Cherry...), at ease for rhythm and solo stuff.
It however compresses the sound a little bit, which makes it not the best choice when you need a crunch sound with very clear articulation and detached notes.
