This is probably one of the if not the best video to very clearly understand the difference between spruce and cedar soundboards
I appreciate you sharing this information. Excellent resource!
Very interesting presentation. To my ear the engelman spruce when tapped always has a more musical sound. When you look at the spectrum it appears that the engelman has lower values between the harmonics -- the curve dips down more. Could you please comment on whether this damping between harmonics is a real factor in how musical an instrument sounds? Thank you.
Thank you Garrett for sharing your knowledge with us. What a great series!
Another masterful video into the world of guitar building. Thanks for sharing your insights.
thanks!!!
Thanks a lot to share your knowledge. It's awesome.
I've been watching and trying to learn from you . Straight forward logical information . There's a recipe in all this somewhere Garreth . Peace ✌
Very good, thanks!!!
Oh, man. Finally some science interjected into the acoustic world. Love this stuff. Subscribed, and PLEASE more videos like this!
Thanks for the extremely encouraging comment. I hope you find these videos helpful.
Magnificent!!
The most complicated thing for beginner - as I understood from this video - is selection of the board's shape one should keep his/her stock of soundboards))) To get consistency of comparison in future...
To be serious, thanks for video! Now main factor for me is "I like tap tone" or "I don't like tap tone"... the time has come for me to buy notebook and start writing down all data for comparison.
Hey Gareth thanks for your great video's. Im also trying to apply science in my builds and explain why things are happening. I have 2 questions maybe some more but i restrict myself to 2.
1. In the first part of this video you have thinned down the higher density board to match the longgrain resonance freq. Based on my calculations, based on normal sized board, the lower density board is about will be around 149 grams vs 163 grams for the higher density. Roughly 10% difference. What is your opinion about that?
2. Did you also consider to measure the crossgrain stifness in terms of resonance frequency, this because the guitar has also vibration in that mode?
Please keep the video's coming.
1) Thanks for the calculation. I believe in the video, the measured change in weight was 14%, so not exactly the same as the 10% you calculated. Keep in mind that these thickness measurements are not high accuracy since I was using a caliper taken at a minimal number of edge positions and that the true thickness can vary around the plate since I'm thinning on the drum sander at high speed and with a very coarse sandpaper. The exercise was to demonstrate the concept that small changes can envoke a change in acoustic behavior and such techniques can be used to gain consistency in final sound. But in practical terms, the higher density board will still likely yield a different final sound due to the extra mass, even though the resonances might be matched in the completed guitar. Such differences may be evident in longer sustain, slower speed of response and possibly altered dynamic range. The point is, if you want consistency, it's best to start with similar material and also try to match stiffnesses and resonances. 2) You'll see in episodes 13 and 14, I begin to introduce the concepts of stiffness in multiple axes and the use of impulse analysis to monitor as many modes of vibration as possible. In future videos, we'll discuss how the resonances relate to modes of vibration using Chladni analysis.
