I have been playing guitar off and on for three years and just recently bought an ESP M-50. I want a new guitar, what do you guys think i should get my price range is 300-600
Why do you want another guitar? Is there a tone you're after or do you just want a new guitar? Also, what amp are you using?
The Jackson DK2M falls in that range, I'm pretty sure. You may want to upgrade the licensed Floyd in the future, though.

Yeah, what amp are you using? Because if it's shit, and you JUST bought a new guitar, you might want to consider an amp instead.

Soda sucks.
