What tool to use for guitar intonation?

I just use a semi decent tuner for intonation. Heck right now I just use the one in Guitar Rig to do it.

 

You should have a very precise one to do it right, but I figure that by the time you account for issues with nuts, variances in fretboards, my fat fingers pushing a string down; well as long as I am pretty close that is good enough. The guitar is a pretty imperfect instrument when it comes down to it and as long as you are as close as reasonably possible you should be fine.

 

Now as for actually adjusting the bridges, that really depends on the type. Usually just a few screwdrivers or hex drivers, whatever fits and a lot of patience. Oh yeah, I always do it with an old set of strings on it to make sure that they are good and stretched out.

One important trick I've not seen mentioned in your threads is to check the adjustment with the guitar held in playing position. However you normally play, check it that way. Reason being, if you check it lying down, the pressure on the headstock will screw it up and give you a false reading on the tuner.

 

For tools, it varies. On my Charvel, I need allen wrenches. On my strat, a phillips screwdriver, on my LP, a flat screwdriver, on my SZ, a phillips screwdriver. What kind of guitar are you adjusting? Specifically, what kind of bridge does it have? A pic would be helpful.. You also need a tuner. The human ear can almost perfectly match 2 tones playing simultaneously, but you don't play the notes together when setting intonation. You play one (the fretted 12th) then you play the next (12th fret harmonic).. You won't be able to hear the few cents worth of difference in the notes. You NEED a tuner. You don't, however, need some super expensive strobe tuner. A $20 tuner is sufficient. I use the one built into my POD. It comes up on my puter screen and is as precise as I've ever needed.

NO. And you put the hammer and impact wrench away too!
:)

A quick search of the internet shows
http://www.projectguitar.com/tut/intonate.htm
has good instructions. There are lots of other places too.

 

aren't you supposed to check the fretted 12th against the harmonic? that article says to check it against the open tuning. or does he mean check the harmonic against the open tuning? it's a bit poorly written and ambiguous. :confused:

By nature, the 12th fret harmonic will always be the same note as the open string, only one octave higher. You can check the fretted note to either the open string or the 12th fret harmonic, but never try to set intonation by comparing the 12th fret harmonic to the open string, because physics says that should always be exactly the same, since the harmonic is just exactly 1/2 the length of the string.

When using a tuner, use the open string. When doing it by ear - use the harmonic.

For intonation tools and procedure on how to prepare the instrument for intonation which is the most important thing to perform a correct intonation procedure, I reccomend you link to my Fruduatv channel on youtube (just type it, I don't think I can post the link here). There you will find a "step by step" free video on intonating your guitar the best way.
