Ironically, I’m selling one right now although obviously Mudcat isn’t the place to do it.
I have large fingers and they aren’t exactly slim. I have an Aria SW3 special edition made in Japan in 1980 that is as wide as any classical yet is a steel string acoustic. It is lovely for finger picking, being so wide and the main reason I’m selling is because since buying a Terry Pack small jumbo, I’ve found a 1 3/4” nut width with string spacing that allows everything I want to do.
So;
1) There are some out there.
2) Play a few 1 3/4” and see. It’s the string pitch every bit as much as the neck width.
