Knowing a fake Gibson guitar from the original is always easier in person than by looking at pictures in an online advertisement. If you doubt the originality of a guitar or the reliability of a reseller, don't buy the instrument without seeing it with your own eyes. Some of the signs suggesting that you might be dealing with a fake Hummingbird include improper dimensions, odd graphics of the brand's logo, plastic wiring, and the absence of Gibson's lifetime warranty inspection card.
