| Post subject: | Final setup - intonation |
Hello, I'm dangerously close to finishing my first build (queue Handel's Messiah). I'm following the Robert O'Brien videos and I'm on the video where he covers intonation and setting the right angle on the back edge of the saddle. I followed the steps he outlines using a small piece of string cutoff and moved it around until the intonation was correct and marked it. Pretty much the angle brings it right up to the front edge of the saddle. This all worked well for the low E - B strings. On the high E I have something strange going on. When I play the open high E the tuner (a basic Snark) shows E right on the money. However, the 12th fret harmonic bounces between E (just slightly flat) and A. Also, when I fret the 12th the tuner bounces between E and A. The other strings play just flat or dead on when on the harmonic and fretted 12th, and are showing the correct E, A, D, G, B. I don't have any experience with this so I'm guessing.... is there some type of overtone or maybe a vibration or ....? that would be causing the tuner to read A? Thanks! Brad |

You need something better than a Snark to set intonation. They are fine for general tuning (I have 2), but they just don't have the range for the job of intonation. |

Use the fretted 12th, not the harmonic for setting intonation. |

Thanks for the feedback, Bill and Ken. I grabbed the app for my phone and I can use that 90 bucks to buy some tonewood! |

Not to dwell on it but in case you missed it on the previous post above...use a fretted 12th fret not the harmonic when intonating. |

In the Robert O'Brien video he does all three, the open, fretted at the 12th and the harmonic and tries to dial them in to be as close as possible. Bad idea? |

Harmonic is a useless and unnecessary complication, It will always be near the octave regardless of saddle break point. |
