I'm currently negotiating with a seller for an Epiphone Les Paul Custom which he claims is a made in Japan guitar. I'm having doubts that it could be an early 90's made in Korea guitar. The guitar has no serial number so it probably had a sticker. It has the Gibson headstock, but the thing that puts me off is the 3 screw truss rod cover. The bridge, tuners and pickups have been replaced but the seller still has all the original hardware that was on it. Can anyone help me identify this guitar? Edit: Well i've found out that it's a 1989 Epiphone Les Paul Custom MIK Samick model. I'm gonna replace the emg hardware for something else. Not really a fan of active pickups. The guitar has some nice weight to it.
