    How do they do it at the factory?
    by ear or do they use a tuner?

    My new LP seems minutely out. I have checked it with a tuner ...the g seems to fluctuate for a millisecond then settles on to the green led.
    whereas the e and top b are dead on balls accurate.
    should I fiddle with it or leave it?

    It's such a precision instrument.

    I would consider that as OK.

    When it happens to me I pick with softer attack, maybe with just my thumb just to make sure the "average" of many tuner readings is within proper range.

    Maybe your tuner has a higher sensitivity too.
    Or maybe you subtly bend the string when you test which is more apparent with the g being lighter than 3 wound strings.

    So, lots of factors if you want to be thorough.

    But, by what you describe, it shouldn't sound out of tune when you fret at the higher registers so don't worry.

    And, in my experience, g strings might be a bit harder to fine-tune or intonate sometimes; maybe it's the scale of these instruments being originally designed for wound gs etc etc. I'm not sure about that though.

    Also, being a new guitar, I'm sure you'll change strings sometime soon so you have all the time to fiddle then. Unless you already did so, again, it's probably fine.

    Of course, if you're not 100% happy with it you can keep trying.

    My 0.02. (Could be total BS though,,)
    Enjoy your new LP in good health and play the best out of it!
    Best,

    The majority of LED styled Tuners are chromatic and accuracy is not as good as a strobe tuner. When I got my strobe I noted what my chromatic said was OK was fairly off by my strobe o stomp. you'll never get true tones all over the fretboard, accurate intonation seems to make a big difference in the higher registers.

    My own observation using a strobotuner is that most picked guitar notes are sharp when you first hit them, then decay back towards pitch after about 1/2 a second, I assume the larger arc of vibration when the string is first vibrating actually stretches it and pulls the avreage pitch up.

    Depending upon your style you either tue to the attack (immediate) or dwell (just when the note settles down).

    A good vibrato will fix bad intonation.

    One thing to keep in mind is the guitar is not a perfect instrument by nature, and you will never see perfect intonation. Just dial it in as tightly as you can and press on.

    You're kind of mis-stating the facts here. Intonation between open and 12th fret can be dead on, it's the other notes inbetween that are "off".
    This is simply due to the fact that spacing between each note is identical for all strings across the fretboard when by rights it shouldn't be, that why the scale is tempered.
    If you'ever seen inside a piano each note on the keyboard has it's own dedicated string which is full length and never divided up like a guitar.

    When most people refer to intonating a guitar they mean the two points not the whole fretboard. by changing the length of the string you are effectively trimming the relationship between strng length and scale divisions. So the better the octave is the more "on" the notes will be to a degree.

    equal temperament is a compromise. octaves are perfect. all other intervals are not.
    it is, however an excellent compromise in the sense that it doesn't have good keys
    and bad keys - all keys are so-so.

    the guitar, being a tempered tuning instrument, will never sound perfect.
    but again, being a tempered tuning instrument, it is not supposed to sound perfect.
    it is supposed to reproduce the set of pitches defined by equal temperament.
    if a guitar can do that, it is technically well intonated.
    keep in mind that, unlike virtually every other guitar maker, gibson guitars will
    not accurately reproduce the set of pitches defined by equal temperament
    due to the "old-school" fret spacing they use.
    they're close enough for most people, though.

    Good tool (if not odd), or gimmick?

    I know that looking at that picture gives me a headache for some reason. The fretboard is like one long ripple effect :shock:

    I think I need sleep...

    Just curious. I'm fairly certain I'll never play one, and I've never even really heard anybody talk about them, so I figured I'd see if there was an opinion out there one way or another.

    +1! Very well written!
    That's exactly what I have in mind when I play. If it doesn't sound good, it' s because guitar = tempered tuning instrument = bad = not my fault = I'm good guitarist = my mama loves me = it's late I got to go to bed = See ya!
