My MT2 is 1 1/8. I’m not a big guy so have never thought twice about that sort of thing. But sometimes our front man borrows it for a tune. He’s only doing simple runs and 2 finger chords, but he IS a big guy, 6-4, 260, and he’s never noticed a problem. Well, except from the ribbing he gets from us because the instrument looks so small in his hands.
Some chords you can’t finger the same way you would on a guitar. I know from watching Ben’s videos, that simple ones like that one finger A or E are alot easier once you get used to doing it more perpindicular (well more like a 45 degree slant anyway) to the nut instead of parallel to it.
