rock on dude! isn't it funny how the gibson sg special faded makes you content? I have one too. it's just such good quality it's like I don't even need another electric... well... ok, I do want a tele, but only cause it's a totally opposite tone of an sg.
anyways! I just got a guitar pick holder for like $2... it's a keychain thing, it says "valley music source" on it, which is my favorite shop around here. you wouldn't really think much of it, but it's amazing how much money it'll save you in guitar picks that you otherwise would have lost...
but seriously, I wouldn't just buy a bunch of random crap, I'd get something big. like a digital 8-track recorder. or an acoustic (if you don't have one already)
but seriously, you don't need to spend your money just cause you have it there ready to spend... I know it's tough, but GAS is not always a good thing, don't just buy something cause you want it that minute, wait till the next day at least and see if you still want it... chances are you won't... and if you do, then GAS away.... now.... if only I could follow my own advice...
now, going against everything I just said, I must say George L's cables are a must. I got a premade 15 ft. one from musicians friend for $30... and I compared it to every cable I could. this thing sounds ALOT better then anything else, it's not like a subtle difference where you can't even tell, it's dramatic improvement over any other cable I've used in the price range. this doesn't mean go out and buy $500 worth of cables though, 1 or 2 should get you by.
