The size and curvature of the jack plate is on the money. However, when attempting to mount this to my Epiphone Les Paul 1960 Tribute Plus, I had to ream the holes just a little to make it work with the existing screw holes in the guitar. Not the end of the world, but kind of a pain. My guess is that even though it mentions Epiphone in the part description, it is probably designed as a replacement for Gibson guitars. Other than that, this worked out perfectly, and really ties together all the other subtle mods on the guitar. I would buy again (but not for an Epi).
