Ok, after seeing the unscientific way of measuring string height, how the hell do you distinguish .1 mm with a ruler????
I checked my action with a set of Gauge blocks, (I'm a machinist ya know) here's what I found
Measurements are Low E first (or B) and then high E
JEM7VWH *.029" * -> *.028"
JEM777DY *.043" *-> *.029"
JEM77FP * *.035" *-> *.032"
UV777BK * *.046" *-> *.031"
UV7BK * * * *.045" *-> *.031"
540S * * * * *.028" *-> * .024"
RG custom * .029" *-> *.011" *but the neck is twisted on this one and it doesn't play for sh!t anymore so it doesn't count.
just so you know, .03932" = 1.0 mm
If you want to know what these numbers are in mm, just multiply by 25.4
None of my guitars except the UV7BK have any fretbuzz anywhere and the UV7BK only does because the frets are worn pretty bad.
Some of these numbers might seem pretty far apart, but when you consider that a piece of writing paper is about .0035", then having .010" difference between guitars is pretty good I would say.
