I was browsing new models at Martin online. All of the ones I looked at have a nut width of 1 3/4 ". Is this their standard now? Whatever happened to 1 11/16? I'm glad I bought my M-21 when I did. Now I'm not pretending to be an authority on Martin guitars and I know lots of folks like a 1 3/4 nut but can we not have some of both?
