Just as a point of information, I was carefully evaluating a Rainsong guitar for purchase earlier this year. I made a bunch of careful measurements all over on my 414 and my Rainsong, including the string-to-string width. Although our Taylor necks are 1-3/4" wide at the nut, the actual E-E string spacing is almost exactly 1.5" (center of string to center of string). I did not measure the GS Mini. I'm intrigued by a wider string spacing for the Mini, especially if it is as easy as switching out the nut. So I will be following this thread with interest.
