the new epiphone SGs suck cos they're made in China. believe me, i've got a fren who has that guitar and he's beginning to think that SG stands for Shot Gun.
apart from the warped neck, u can't reach the high frets because the neck is slotted in further than the real Gibson SG.
get the 2nd hand one in guitar77 made in korea. exact replica of the Gibson. it's onli $400. of much better quality.
