Well...I'm an old geezer that's had every kind of guitar imaginable....
I went thru the Les Paul thing many years ago when I was young and the weight didn't make by back ache.
What ya gotta be careful of is this..new epis like many of the import guitarts are not always constructed of the best aged woods.
They're more sensitive to changes in humidity and heat..also..some of the hardware, particularly in the switches and pickup harnesses can be tacky and noisy.
The pickups and pots are iffy..I have a Korean Epiphone Casino..I bought it right off the wall and haven't changed a thing.
I know another guy who bought one and had to change pickups and hardware and tuning pegs..ya just never know.
That's the real difference between the imports and the guitars made here in my opinion..consistency.

Don't expose your new guitar to extremems in temperature and humidity..the fingerboard woods can shrink and then you've got a problem

All in all, the odds are that your new epi will sound great and play great till you get that record deal and can afford to buy a 59' bookend quilt top!

Enjoy your new guitar
