Hi,

from my own experience starting in Jan of this year, medium hands. Yes nut width definately made a difference for me, but now that I have more practice I find I can do pretty good on narrow necks.

1 11/16" = 43mm

1/3/4" = 44.45mm

I have guitars in and around these figures. In March I purchased a Seagull S6 with a nut width of 45.72mm's. I loved it and still do. It was like somebody said, "buddy, take a break and make things easy on yourself." Those little mm's do make a difference in my opion to those of us who are still training our fingers!
