Honestly, I don't. People say a lighter piece of wood is better for resonance and tone. I don't believe it. I think the resonance and tone come from how beefy (heavy) the wood is. Basically, more wood = more tone/resonance. I love a good, hefty beast that has some real density to it. Any guitar that feels heavy tends to just play and sound better to me. Although, I know people don't want a bag of bricks around their neck when they're onstage for hours at a time and that is easy to understand. For me, it's a sacrifice gladly made. I like guitars to feel like if I hit someone with them, it would do some damage. Weird, but whenever I consider a guitar, I like to do a few practice swings just for fun (I'm crazy, I know). What do you guys think?
