Re: Buying a JEM!
Yeah, what he said^. If you're only a beginner like you said you don't need a $2000 dollar guitar, especially since you don't know if you're even gonna really stick with it. Assuming youre playing a beginners guitar right now i would go for a nice mid-range RG or something of the sort. You can grab one with nice dimarzios in it on e bay for something like 400ish.
I started off with some piece of crap epiphone and waited about 8 months before I got "good" (I have kind of ridiculous standards for what "good" is lol), then I upgraded to a nice Ibanez Destroyer (the DT420), and have been through dozens of guitars since and am now on a straight up custom-built guitars only kind of deal. They're certainly not a good investment but if you're buying guitars to play 'em rather than sell 'em, and you have the money for something like a JEM, my opinion is it's cooler to get something completely built for ya to your specs and have it be unique too. There's my 2cents.
As for the whole "deciding if its fake" thing, if you're not sure you can just post it here and people'll tell you. Folks here seem to do that all the time and get an answer pretty quickly.
