That's a good point. Mine is a long scale. I do have a set of LaBella 2001 light tension strings lying around, maybe I will give those a try, but I do like the August Regal\Blues on another guitar.
I think I have to work on the nut on the Yairi a little bit. Barring at the 1st and 2nd fret seems a little harder than it should be, and the neck seems straight. I'll have to get out the feeler gauges and check the nut height.
Life is too short to be perfectly in tune.
