Doesn't matter if you're doing concerts or not...think of guitar gear as you would a car. You drive a Honda...but you always want a Porsche, even if you're not sure you can drive the thing. Basically, your sound depends on you, but I have to admit, you always sound better playing through something bigger, louder and more expensive. I could recommend a setup for you, but A: I'm not sure what sound you're looking for B: I'm not sure what you want to spend and C: What may be good for me, may not be good for you and vice versa. Honestly, I'd stick with what you got and keep plugging away. Wait until you feel you're good enough to invest (and I say invest because to me that's what it is) in something more expensive. When I was 15 I bought a Kramer Focus (This what when EVH was endorsing them). It was a hot guitar. One humbucker and two single coil, a Floyd Rose locking tremolo, solid body and a rosewood fretboard. It set me back about $700 (I just wanted to state that because I don't want anyone to think I bought one of those cheap ass Kramer's on the market now). It was a great guitar, sounded good etc.. but I always felt like my skill wasn't up to playing an instrument like that. Needless to say, I did get better, but I felt it hurt me in the long run. I would avoid playing for many people because I figured they'd be saying "Oh, great guitar, but he's not good enough to be playing something like that". I know it's bull****, because you shouldn't worry about what other's say, but I was a teenager..and I did. Okay, sorry about the rambling! Bottom line: When you're ready, try numerous guitars and amps to see which one suits you.
