I'm about to buy my first Gibson ever. A Les Paul Studio. I'm a complete Gibson novice so I'm wondering if you guys can help me decide whether it's worth the $500 asking price. It's from an online shop and the date and serial number are not in the description. They say it's in very good condition, although it's difficult to judge from the low resolution photos. It does not come with a case. Too me, the price seems fair for a USA Gibson, but I know that Studios are generally a cheaper class of Les Paul. Should I bite? Is there anything I should be aware of like quality issues, etc.
