When I was in Shanghai, all kinds of Epis and Gibsons were faked. Some not so obvious, others DEAD obvious...... like epiphone pickups on a Gibson guitar..... the Zakk Wylde Bullseye that has EMG-HZs written in what I assume is Liquid Paper (REALLY) and like, Les Paul Custom bell cover (with 3 screws mind you) with Standard trapezoid inlay and no bindings.....
