Get active in the local music scene. Go to small shows and talk to people. You would be surprised at the kind of people that come out of the woodwork... Get to know people. The biggest thing about the music scene is building your social pipeline. "It's not who you are, it's who you know" That is soooo true. So get out and meet people. Even if one person doesn't play guitar... maybe they know someone who does, or someone that's a hell of a vocalist. Also, be patient with the process. Sometimes bands are formed by a stroke of luck. Sometimes you get a group of guys together to jam and there's no chemistry... so be patient and wait it out. If you can't find a band right away try to get some kind of an acoustic act together and do some shows. You'd be surprised at how many people will come to you and say 'hey man, let's jam sometime!'
