here's a fun one... I already blocked the OP...
Your 2015 Epiphone Thunderbird Classic IV Pro might be a rebadged 2014 Gibson.
not sure if they shipped the fully finished gibsons overseas then painted them with poly, or for sure how the delusion goes... the op got panties twisted pretty quickly....
I didn't read the thread (at work; my break isn't that long
), but thought I might add something here, some info I found out while (re)building my Classic Pro. Possibly the quickest way to tell between an Epiphone Classic Pro and a Gibson, based on parts info (I have no Gibson to independently verify), is the string nut.
Gibson allegedly uses 3/16" thickness, while Epiphones (all of the ones I have are this way, including the Classic Pro) use 1/4" thickness.
