So I post this out of sheer curiosity, and the desire to know just how much woods actually have to do with the tone of a solid body bass. let me start off by saying, I am not asking for opinion, I asking for help in how to test it. But I digress, every forum post on this topic I have ever read has ended in some variant of a "flame war", with both sides interjecting some opinionated factually inadequate statement. I also read a lot of posts saying how there has been no scientific test to back the tone wood hypothesis up. This brings me to the point of this post- I feel it would be interesting to approach the debate using a less bias viewpoint. It would be amazing to create an experiment to test how much woods have to do with tone. So, lets begin... Using a logical approach, it seems it would be possible to construct an experiment to test the variables of the problem. As per the rather generic scientific method, I've just asked the question. Hypothesis: Based on many years of playing bass, I suspect that woods would have an affect on the tone of the instrument. I suspect that the differing densities of woods would be the primary culprit. Having stated this, I understand that there are a lot of factors that make a bass, a bass- I.E. strings, scale, pickup placement, electronics, ecc. I find that even playing identical models of instruments produce obvious tonal variants. Granted that the aspect of strings, and pickup hight can also play a role in the tonal differences. But I feel it isn't quite all left to that. It seems that the nuances in the densities of the wood could be part of the cause for these differences in tone. Also, don't take my word thus far as anything completely factual. So far I have stated my opinion. But this is my hypothesis after all, and that is what a hypothesis is: an educated guess. Experimentation: Now this is to be one of the hardest stages: testing my hypothesis. Im not entirely sure how I may go about testing it... But this is why I've posted this thread, after all. There must be several factors in this experiment. The first being consistency. This includes the ability for this experiment to be retested, and the ability to attain a controllable testing method that minimizes error. I will test how sound, (the vibrations) of the strings affects the wood, and how it changes how the string is vibrating. Secondly, the testing of different materials with the same specifications. I will have several different woods, metals, and even some others as test fodder. There will be one bass pickup with identical bridge, string, tuner, and electronic connections. The pickup will be identical heights, and the placement will be identical on the whole of the set up. (see included diagram below). But this is the tedious part: I do not want to just use my ear, as this is completely subjective and hardly accurate. There must be a way to accurately rate what is happening. IE an electronic ear that can measure the differences in the materials. Yes I understand that this may be a bit ambitious, however I feel it could be feasible to accomplish. Secondly, this I hope will not turn into a flame war, that is not the goal of this post. Also, To who ever might say why knowing this matters, I say: The goal is to learn, and when seeking light on a subject that hasn't reached any type of conclusion, I see it as "worth it". Lastly, Im not sure how to proceed experimenting, help is something I need... How would you guys go about testing this idea?
