There is a mystic force that has been teaching guitarists of all styles to play guitar.
Hendrix: Nope
Stevie Ray Vaughn: nada
Van Halen, Clapton, Malmsteen, or even Les Paul??? No on all accounts
It's Mel Bay. Go find one of his beginner’s books. Millions of guitar players started with him and are better of for it.
If you want to play guitar, then go to your local music store and look at a few lower end guitars. I've know of dozens of people who went out and bought top of the line guitars only to lose interest and have them collect dust. If you want a better guitar then learn to play first and use it as incentive to practice and get better. Don't worry about double cutaways and other cosmetic factors. Find one you like playing. As you figure out what your "sound" is then your figure out what kind of guitar you want.
Also ask if they give lessons. A lot of "self taught player" will never admit to taking lessons or learned from friends who also played. Learn the basics first: chords, scales, notes on the guitar and how to tune. Start by learning Mary Had a Little Lamb, Jingle Bells, Camp town Races, Iron Man and Smoke on the Water before you move on to other songs. (Actually Green Day isn't much more complicated then those songs, but it's good to know the chords)
If you want to play bass then play bass. Most bass players I know can spot a guitar player who just picks up the bass from a mile away.
