What I Can Do |
The Problem:
Guitars and other fretted instruments are
rudimentarily intonated when you buy them in the store. The manufacturers don't have the
necessary knowledge and they rarely meet the final customer. They don't know what strings
or what setup the customer prefers. For a couple of years I've been studying the problem and analysed the sources of error. The faults are:
There is one more complication, but we can ignore it. It is too small for us to apprehend and we can't do anything to correct it anyway. When the faults are analyzed, we see that they both cooperate and counteract. In the bridge the first two faults cooperate, but in the nut they counteract. If a fretboard has the right amount of reliese to compensate for the "clothesline effect", these faults can be perfectly corrected by compensations in both the nut and the bridge. The problem is to find the right balance between the nut compensations and the bridge compensations, for if the release point is moved in one end of the string the release point in the other end of the string will be affected. By measuring the faults, I can calculate a perfect balance between the compensation in the nut and the bridge! That's my business idea. |

The Result:
The remaining faults are smaller than the human ear can
apprehend. That's what I mean when I use the word "perfect" or "
correct". A good musical ear can apprehend a difference between two notes
of 3 - 4 cents ( 1 cent = 1/100 of a semitone). At 3 cents I can feel a difference
but I can't tell which one is sharp or which one is flat. I can intonate better than that. Once I intonated a guitar built by Swedish master luthier Michael Sandén. It had a zero fret and intonated rather well. At the zero fret the three heaviest strings were 0.5 cent false and the three treble strings were about 1.5 cent false. I didn't want to touch the zero fret, so I intonated the bridge only. However, this customer (Petter Hölaas, Intelligent Sound) was not satisfied. He is blind since early age and his hearing is extremely developed. I had to compensate the zero fret with composite under the three worst strings. Then he was satisfied. |

I can intonate so the remaining faults are less than 1.5 cent! |
