Call me a complete n00b but I have a kind of question. I've got a new guitar (acoustic) buyed yesterday never even touched it. But can I play these music sheets on my guitar? Or do I need some wich are specific for a guitar? Please help...

these music sheets are aimed at piano mainly with some exceptions either way they all use the same style score. with guitar you need to look for tabs not sheet music. there's a link on josh's site for guitar tabs its animetabs.com i think. check it out

Moving to music forum.

With any guitar, yes, you can read sheet music. You just can't read both hands of piano sheet music; therefore, it is recommended that you read the treble clef parts, since a guitar can't go very low on a bass clef anyways. ;)
