i've been playing guitar for about 4 years now and i still have my first guitar. (squier strat). i've also installed a killswitch on it but im wondering if i should buy a new guitar and sell my strat, or dont buy one at all, OR buy a new guitar and keep my strat.

Any suggestions?

(And i have about $350 to spend)
Me personally I say keep ur first guitar because you can always go back and mod it, and if you ever have kids it makes a perfect guitar for them.
I would wait and get a bit more money. It all depends on what you want. I recommend buying a 1/2 decent used guitar because you can get an amazing guitar but at 1/2 the price. I got an ESP LTD deluxe for $400 used. I would keep the strat since you'd get only$50 for it and it is not worth it. Do your homework. find out what you want. what type of neck and all that stuff. Then browse www.instrumentexchange.com (guitar center online) and see if they have anything at a good price. keep checking until you find what you want. Be patient good deals take a while!
