Hey everyone, I bought my guitar on the 30th August, a while ago, its an Epiphone SG 310. I know it wasnt going to be the best thing ever but its seems to be really similar to my Aria Strat Copy apart from the tuners. Does anyone know why? Is it cus im such a n00b at guitar I cant tell the difference or what?

Also, whats it made out of? Lots of sites say different things, ive heard Poplar, Hardwood and Mahogony but I dunno what mines made outta. Where can I find out?

Also, would it be worth me replacing the pickups or save up for a better guitar?
