Looks just dandy. Sand out nicely, hit it with a bit of wax or Howard Feed'n'Wax and you'll be good to go. OR - finish it with super glue, then buff out. Maybe even TruOil? I'd have to try all methods and see what yields most pleasing result. |

Last winter, I tested a new bracing on a Ukulele. Once finished, I did not like the sound of it. Difficult to describe, but I would say dry, harsh. It had bone nut and saddle. I was resigned to reopen it and change the bracing. This conversation got me thinking about changing the bone nut/saddle for African Black Wood. So yesterday, I made a recording of a strum, made a new nut and saddle and installed them and made a new recording. I could see a difference! And the sound is better. To make sure, I reinstalled the bone nut/saddle and recorded a new strum, I got similar results. The first graph attached is the spectrum of Bone (green) and ABW (yellow). There is not much difference in the frequency spectrum , except the tuning of one of the strum was slightly off. (this make it easier to see both curves) The second graph is a comparison of the 2 wave graphs. First when I saw a difference, I assumed it could be caused by the different color. So I made them both the same color and changed the background to black. The Bone graph is more "porcupine" the ABW is like more "structured". I am not sure where to go from here, but I will leave the ABW on!. |

Here is the Wave graph. Top is Bone |

Alain, I have had occasion to use your software in a similar fashion. I have been asked lately to make some changes to a couple of guitars - I often record a guitar before and after a change to see if I can detect the difference but in these cases I also ran a spectrum analysis on it. Recently a young lady brought her classical guitar to me and asked if I would replace the "plastic" (Melamine) nut and saddle with bone. Along with some audio clips I ran analysis on a few notes before and after. I usually do single notes rather than chords or strums or songs. If I listen to two A2 notes for example can hear a difference - more complexity or brighter or longer sustain or any of those things we talk about. Then can I see it in the spectrum - a different mix of partials or certain partials stronger or .... Anyway, here are two graphs of the open A string and two of the open E string. I chose those because both the nut and saddle would be in play and they pretty much cover several octaves. I also like the fact that the E4 is a partial of A2 - should I expect other E's to show up in the mix. On each pair of graphs the top one is the "plastic " nut, the lower one is the bone. Attachment: Classical - A.jpg Attachment: Classical - E.jpg The difference are subtle as you would expect, and a lot depends on how the notes are plucked, room acoustics, yadda yadda. My little experiments are not at all rigid, it would fail as even a high school science project, but it does give me a little more information about the guitars that I am working on. I want to formally thank Alain for making this software available - I'm not sure yet what its telling me but I'm having fun. |
