Hey guys, I recently purchased an Epiphone G400 SG, and I put new strings on, and the second string buzzes real bad when I play it, how do I fix it?
Is is buzzing when you play it open or just when you fret it? If it's just when you fret it, then you're not applying enough finger pressure. If it buzzes when you play it open, then the action is too low. Electric guitars are designed so that the action is easily adjustable; look for a screw that raises the bridge. If you're not comfortable making the adjustment yourself, take it to a repair shop.
Go ask the Electric Guitar forum. I'm sure they'd be glad to help you out.
