So I've been playing bass for about a year and a half on a used peavey, and i think it's about time to step it up. I want a bass that sounds nice, but i'm not scared to play, ya know? I want a bass that will give me lots of tonal options, and sound good doing them, but I want to be able to beat on it too. I play anything and everything, and i'm not afraid to do some mod's if needed. I don't care what it looks like, so long as it is functional and playable. any suggestions? My budget ends at $600, but i would like to spend as little as possible, so i'm good with used gear.
