I also play 12-string guitar. If you've mastered 4 strings -especially bass-then,believe me, try a 6-string and your life will really open up with different types of music. Bass guitar is like a lead six string with 2 added, but I couldn't do that, as I'm a rhythm guitarist. Give 6 a try with a "Washburn" with good tone and low action on the strings. You may surprise yourself!
