Just bought this from kobass. Its literally in absolutely perfect condition. I just got it Friday, but haven't used it yet, because I decided to keep my epifani rig. Unfortunately I got rid of my UL502 in a bad case of GAS, so I will trade this for a UL502 or outright sale of $700 shipped. No other trades at all. I havent even used this head yet, its in perfect condition. Im just gonna link his thread for pics, its in the exact same condition, Ive had it for two days.
