Hi graph man, not entirely guessing. I ran a few experiments that indicated to me it's related to the open back scale. I posted some fairly extensive descriptions of what I tried, and what I found. No one has said it happened evenly throughout the scale, but on the basis of my samplings I'd expect to get the effect wherever the back scale is open and long enough. How much each note is affected changes from note to note, presumably because the speaking length/back scale length/frequencies mix is different for each string. That makes it unlikely that the tuner could anticipate the effect and pre-compensate on the fly. I don't yet know the proportion or frequency limits, but I haven't abandoned it just yet. So far, no one else has reported trying the quick and simple experiments I posted to verify or refute what I found. I'm still building tools to pursue it further. BTW, that was Kent Swafford, not Keith. Ron N
