So, this is probably known, but what are the major differences between, say, a Epiphone Plus Top and a Gibson Studio (the $1300 one, not the $800). Tuners, pickups, hardware, I know that's higher quality. But what about the actual wood? The inlays? The construction? Finish? What makes it worth $800 more? The name? Made in USA? If a Plus top can be had for $500 ($300 if you get used), and can be upgraded to similar hardware as a Gibson for say $300, what are the real differences we're looking at here? What can't you really change without spending more money than it's worth? Honestly, I'm just curious. I know Gibson LP's are quality, but I wonder how far off an Epi LP is.
