Hi! For years I had this guitar, allegedly a Epiphone Firebird, bought second hand. I was trying to verify if it was a real Epiphone or a fake. It shows no serial number anywhere (not in any part of the headstock, cavities, etc. As far as I concern, all hardware matches exactly those used in some of the brand models. Had original Steinberger tuners, pickups... I made some mods throughout the years (lighter locking tuners, strap locks, shield and screws). Does anyone know a way I can verify it? Played many Epiphones and Firebirds for a long time. Can tell the feel, construction, finishing, all refer to the other models I played. Here in Brazil there are some copies that comes from China, but given my own opinion, my luthier evaluation, it speaks to me as an original product, with very superior construction and similar to some Korean Epi's. Didn't find any guitar like this (not even any information about Firebirds with humbuckers + block inlays). If anyone can help, I would be grateful.
