I did a pretty big update to my web tools last week. These are updated from the older versions I had up on celestialinstruments.com. There’s an updated FFT tool now, plus mode detection for guitars and plates, wolf note detection, played-note energy transfer, monopole mobility, plate thickness calculation, and 1/2/3/4 DOF modeling that can be prefilled from FFT data. The part I’m most excited about is being able to fit a measured guitar re…

Hey folks, I put together a video showing how I measure the long, cross, and transverse frequencies on guitar top plates before thicknessing, following the Gore method. I also walk through using the calculator I built (based on Trevor Gore’s equations) to get target thickness and track density / young's modulus. Fair warning: the video’s a bit YouTube-y in tone thumbnail faces, a little energy for the algorithm, but the content is genuine…
