Low frets appear sharp on tuner even when bass is otherwise perfectly in tune? Recently had my Fender Jazz set up by a professional, but when I took it home I noticed my low G (third fret on E) was going sharp even when my low E was perfectly in tune. Frets around the low G had a similar issue. When I play a harmonic on the 12th fret of the G string and the low G on the 3rd fret of the E string it doesn't really sound noticeable, but on a tuner it comes up as almost 20 cents sharp every time I play it (on several different tuners by different brands). No other tuning issues on the neck at all. Is this normal for the lowest fretted notes or is it another issue? Keep in mind I've just had it set up by a professional only about a month ago, and the issue existed before that as well. Thanks!
