The Gibson SG is a very beautiful Guitar. Played by many greats, and often called a poor mans Les Paul, it is actually the Les Paul's replacement. (The Les Paul was so popular they had to reissue it.) Notable Gibson SG players include Jimi Hendrix, Tony Iommi and Angus Young. There are many different models you can obtain, including the Angus Young Signature SG, which is the AC/DC guitarists personal favourite.
