What is Biggest Difference between a Gibson Les Paul and or an Epiphone Les Paul?

The headstock on the authentic USA made Gibson Les Paul is the first clear difference between the two. The shape of the headstock at the very top of the guitar tells you right away, no need to look further. The image below shows it clearly.

The American Made Gibson Les Paul has sharper lines on the edges and flare out, almost like a moustache. Like the rest of the guitar, just a sharper looking guitar. With top quality pickups, tuners, bridge and neck but it’s the craftsmanship and set up that sets American Made Gibson Les Paul Guitars above the rest.
5 out of 5 star rating for any USA Made Gibson

The Epiphone Les Paul has a softer look with cut corners. Just like the rest of the guitar, less quality pickups, tuners, wood and overall set up and construction.
