Got to remember that I come from the classical world where I played a violin for 10 years. Now I was always interested in how a instruments sound can be tweaked after it was built. Old violin builders used to hang there instruments in a blacksmiths shop for a while hoping that the loud bangs and clacks would add resonant frequencies to there instruments or in effect make them break in a little bit. I think that this is a bit bunk but on point a little bit. Some people think that its micro cracking in the finish but I digress.
I think that when a builder builds a instrument they are thinking of the soundboard moving in one plain, up/down. When in reality the soundboard moves left right up down, and distorts into some really interesting plainer shapes. So when it does this the glue loosens up, the instrument just settles in. I want to speed the process up, some of my instruments have 100's of hours in them and the sound has changed dramatically. So I figured if I pipe a bunch of pink noise, a quick wave form or two focusing on the freq. that I think are important and a bunch of the best ukulele music that I can find with some bass added I should be able to et them to do the same thing.
Now I have also hooked them up to a shaker table to see if its movement, I have not yet tried a temperature swig test as I have not had time to program a incubator yet but the theory is to trow 10 years worth of playing time into a instrument without actually playing it.
This does not sound like fun, but since I am starting to build my own instruments I figured I might as well see how they age and see if I can correct for coloring of the sound by building in a protection against it. Or if I can really change and shape the tone by doing the equivalent of playing the instrument for 100's of hours.
I also want to go to a violin style finish on the instrument and I really think that it takes time and a good knock or two to get that to sound right, personal opinion take it for that. All I could be doing is nothing, or prematurely aging a instrument a couple years.
