You get an extra low string (tuned to B)which does take a little getting used to at first. When you think you're playing an A but its really an E. UGHHH!!! But the sound is so cool on those new lower bar chords(B,C,C#,D).Once you get used to going 'down there', its hard to go back to 6-strings.On the negative side, the wider neck can impose some problems when soloing but on the whole, I love it.
