Hi Oswal, in case your still checking this thread, I play blues guitar and love it. It really is pretty easy, you just need to know a few riffs and chords. A great tool I used to play blues guitar was Blues Guitar for Dummies, which I got at Barnes and Noble. Or, this is free and you can do at home: listen to your favorite blues songs, or blues inspired songs (there are quote a few by the Beatles) and look up internet tab for them. That will teach you alot, good luck!
