I have a Yamaha 12-string that I love. I have short fingers so I have tuned it down a step so I can play it with a capo on the 2nd fret. (I think I have that right.) I have been working on learning to pick on it. I have been thinking about switching both of the 3rd strings so that their positions would be reveresed. On my 6-string I do most of my picking on three strings, the 2nd, 3rd, and 4th strings. I'm hoping to do the same on my 12-string. Switching the two 3rd strings would make it easier to pick the lower 3rd string, I hope. Would this make the delightfull strumming sound different?
