Heya ya’ll. Long time Electric guitar player but just looking to get into an acoustic a bit. Seeing guitar Nut sizes in the inch and 3/4 size. I have pretty large fingers and wondering if the extra spacing would be a good thing on the nut. Wondering why some guitars have such a wide nut? Flat picking? More room is more comfortable? Love the sound of the Martin Guitars and noticed the Specs on the Neck Nut is often different in size. I am just looking for a “Geetar” to play some rock classics or maybe campfire style songs that I do not have to plug in. 
After many years of playing my Fender Jazzmaster I never gave it any thought until now and as a matter of fact I never even measured the Nut LOL. Any advice is appreciated.
