Welcome! I think Phil X gave the best "first guitar" advice when he said to buy the guitar you like to see. If you're a Slash fan, don't buy a strat- get a Les Paul-style guitar. If you like Stevie Ray Vaughan, get a strat-shaped guitar. Pick the guitar that inspires you to want to pick it up when you see it on the stand in the corner of the room. This is the one (possibly the only) time you want to 'listen with your eyes' when you're guitar shopping. Likewise, Phil also said to learn guitar by learning things that apply directly to the songs you want to learn. If you want to play Highway to Hell, the A chord should be the first chord you learn!
