if you want reviews... then here you go: http://www.harmony-central.com/Guitar/Data4/Epiphone/G_400-1.html
but, I can't really speak of this guitar from experience... I believe that my girlfriend's brother has this guitar (he has some kind of epiphone sg, I think it's a g-400) but, if you do end up getting it, let me know how it is, because it's one of the guitars I was considering getting.
