I know that the nut on my USA Fender's vs the spec sheet on my MIM's are suppose to be the same.
But there is no way.
I have a 2004, and a 2009 MIM strat whose necks are way narrower than my MIA strats.
I am 5'11, 185-ish... with small/medium hands....and I have a 1995 Fender USA Standard whose factory neck is so chunky, both in width & girth, I can barely get my hand around it.
The necks on my MIM's are fairly chunky too.... but nowhere near the overall width of any of my MIA's
Because of this, and given that my hands are on the small side..... I literally think I play better on my MIM's.
I don't give a rats ball sack what the spec sheet says on these..... the only thing my MIA's and MIM's have in common is 9.5 radius, that I can feel, and measure.... but my MIA necks are wider by a noticible margin...enough to where the string spacing on the fretboard feels different.
