Dennis, I never said your quote didn't apply, and maybe sometimes I shouldn't be so brief in my replies. I know you have tested the Tune-Bot extensively. I do like mine and I have some hearing loss that leaves me searching sometimes at given frequencies. So the device helps me get near the tuning I want pretty quickly and then, yes, I do the final touches by ear.
Originally you didn't say that you finished tuning by ear, either.
And by the way, my original post still applies since I used the word "but".
