I used to own a Epi LP, and refitted the pup to a 59 neck n JB bridge. The 59 sounds too bassy for my liking, but the JB ROCKS!!!
It is a great guitar to me in terms of tone, however, the joint area of the neck n the body started to crack, maybe due to humidity. Also the cutaway is not too much, so not as gd for small hands like mine.
I sold it, n got a S540 which is lighter and has floyd rose.
Gibson is just a better finished epiphone n made in USA thats all. Nothing worth that price for the quality today.
If u can, get a 70s or 80s greco/tokai copy... These r truly great, as gd as a gibson imho, maybe just swap the pup. Greco r not as famous as the tokai, but that doesnt mean they not as gd... Not as well marketed in US thats all... Heard the new tokais are ok only
OR get a PRS if u can afford the gibson anyway.
Oh, my fren went to thailand n saw the custom guitar builder, and said his quality is 1st class... Gd thing is the wood is seasoned n treated in our climate, so will react better to local weather environment
