OK, so I've been thinking through a design I have for a bass. I plan on have a black limba (korina) core with figured Walnut top and back. Then I thought about a chambered body, with a piezo to accent the nice highs that would be a result of the hollow chamber. My concern is that walnut and korina are generally a dark wood, and might end up with a strange piezo tone. Anyone know if it would affect it in anyway? Good? Bad?
