How do you adjust the intonation on an archtop guitar?

How do I set up my archtop guitar with a floating bridge?

1. First, bring your strings to pitch.
2. If the tuning at the 12th fret is sharp, you need to move the bridge back (away from the neck).
3. If the tuning at the 12th fret is flat, you need to move the bridge forward (toward the neck).

How do you Intonate a floating bridge?

To adjust floating bridge intonation on a guitar, first check the 12th-fret harmonic and the fretted 12th-fret tuning of both E strings (high and low). If properly intonated, the fretted and harmonic 12-fret pitches of both E strings will agree, with none of them being sharp or flat.

Does lowering action affect intonation?

Higher action means more tension which causes the note to play sharp. Low action means less tension. As well, where you play the note on the fretboard effects the amount of stretching and thus error. Action is upstream from intonation so any change in action will affect it.

Where should a guitar bridge be placed?

On pretty much every guitar the bridge should be located so that the break point of the string will be exactly at the distance of the scale length, from the nut. The scale length of any guitar is defined as double the distance from the nut to the 12th fret.

How do you find the perfect intonation on a guitar?

If the fretted 12th fret note is sharp, adjusting the screw clockwise will improve intonation. Turning the screw anti-clockwise decreases the length of the guitar string. If the fretted 12th fret note is flat, adjusting the screw clockwise will improve intonation. Only make small adjustments to the saddle at a time.

What causes guitar intonation problems?

If the tops of your frets are too flat, dented, or you just had crappy fretwork done by a bad guitar tech, you can have trouble setting intonation. If this is the case, you’ll probably have other issues too, such as fret buzz or notes fretting out. Overly flat frets can cause intonation issues.

What is the distance from the nut to the bridge on a guitar?

25.5″ assuming your neck is fretted to that scale. Nut to 12th fret should be 12.75″ and nut to mid way of bridge saddle adjustment(travel of saddles) should be 25.5″.

When do you need to re-do intonation on an archtop guitar?

If you lower the action of the strings, you may find that you need to re-do your intonation. You also will need to re-do intonation if you switch from light to medium strings and vice versa. All in all, if you can’t get your archtop guitar to sound properly in tune, the bridge probably is misaligned.

How do I adjust the bridge on my archtop guitar?

Once you find the position for your bridge, you can adjust the intonation by doing the following: First, bring your strings to pitch. Then, check the tuning of each string at the 12th fret. It should match. If the tuning at the 12th fret is sharp, you need to move the bridge back (away from the neck).

Where do you start to set intonation on a guitar?

Start at the first and sixth strings: once the two ends of the bridge are in place, the rest should be close to proper intonation as well. You will need to loosen the strings in order to move the bridge, and only move it a little bit at a time if the harmonic and the note are close.

How do you check the strings on an archtop guitar?

Take a small scrap of paper, the size of a small Post-It. Check each string individually by pressing the string down at the third fret, and sliding the paper between the bottom of the string and the crown of the first fret. You should feel just a small bit of resistance as you slide it back and forth in the gap.
