Your singing's not bad dude. A shit load better than a lot of other guys who think they can sing. It sounds okay. The guitar sounds a bit dull though. How are you recording?
Marshall amplifiers are the truest purveyors of rock and roll known to man.

"And give a man an amplifier and a synthesizer, and he doesn't become whoever, you know. He doesn't become us."

Holy crap, check this out!

Sounds a bit nasal and thin. Maybe work on adding a bit more depth to it?

I could certainly enjoy listening to it though, so that's not a major problem, I just thought you might want to know what to work on.

you sound like early green day. Has a very singer/songwriter feel to it. Maybe open up that soft pallet (sp?)
