actually it's really a bad imitation:
1. in the 10th picture, it shows rosewood fretboard. customs have ebony fretboard.
2. seller mentioned Gibson hardcase. the one in the picture is definitely not a gibson case... coz there are combi locks at 2 locations.
3. Gibson DO NOT put gibson stickers on their pickups. those stickers were meant for Epiphones.
4. Custom have 3 ply binding at the back of body. this one is missing.
5. where are the paper works as mentioned? seller will be eager to show in pictures. but not this seller obviously.
6. seller said made in 04. but serial number says made in 03.
7. there is a custom historic chop... but i don't think custom shop serial numbers are like that... (i may be wrong.)
8. like some of you mentioned, the diamond inlay and "Gibson" inlay is really out of shape... truss rod cover is in bad shape. missing fret edge binding.
9. heel is too squarish. Gibson's are rounded.
10. seller mentioned open pickups, but obviously there is pickup covers. seller really doesn't know anything at all...
you can compare side by side with a read gibson at:
