When I moved to short scale, I immediately clicked with it after playing 34" for two decades. Nut width and neck taper is different,
you get used to it but it takes time. When I completed my first EB0/6 conversion, laying out nut string spacing was tricky. I usually make equal distancebetween outside of strings, but ended up with wider spacing between EADG. Took about a year to play the six stringer properly, but now I have no problem going from EB6 to EB3 - as long as the nut width is the same (about 44mm) but if I pull out my later '67 EB3 it's not comfy at all.. too skinny, at 38mm.
