I believe he said this occurs on every guitar he plays, did he not??? If this is the case, the common denominator is the player, his ears, the tuner, and not the instrument. No?
could indeed be setup issues, but the thing is, that low E may well be out of tune with itself!One more question.. My Low E string. I actually have to tune it below standard or it is out of tune compared to the rest of the strings. When I tune it to perfect pitch (says the tu-2 and the one i just downloaded), then its actually sharp when I play chords. And I am not sure whats causing it to come through on the tuner that way because if I play the open high E string and tune it it, it sounds good, but stil comes in Flat on the tuner.

a bad string, or one that's sitting on bad nut and saddle slots, can actually have its upper harmonics be a little sharp compared to its own fundamental. your tuner reads the fundamental, but your ear hears the upper harmonics more.
this is especially true of bigger, lower-tuned strings and shorter-scale instruments.
piano tuners live in a whole world of this phenomenon, where they have to decide which set of harmonics on a given string they want to be in tune with other sets of harmonics on other given strings!
