Re: Soundboard Sonic Signature
The bridge weighed in at 35 grams, so quite heavy... Yes, that's over double what mine typically weigh. Is it much heavier than the bridges on the other guitars? Have you and O’Brien rescheduled your class dates yet from July 2020, early days I guess? No, not yet. Still too many unknowns, unfortuna...

Re: Soundboard Sonic Signature
I've found the following to be a handy reference, and build to these resonances...it seems to work! I like my T1(2) to be higher, I don't really get excited, as a player, with those boomy dreadnought sounding steel string guitars. They seem to lack clarity between each note with low attack and lack...

Re: Soundboard Sonic Signature
The figures from the walnut guitar seem to imply it has a heavy bridge (relatively low T(1,1)2, relatively high stiffness). A heavy bridge would explain the lack of excitement in the sound, as it will be less responsive to higher frequencies. How heavy was the bridge? Thanks for this Trevor. The br...

Re: Soundboard Sonic Signature

Re: Soundboard Sonic Signature
They’re each around 2° The structural build, the stiffness of the x braces forwards of the bridge are all very similar. I wouldn’t have expected them to vary wildly anyways.

Tone Bars
There is very little discussion about the use and importance of tone bars in a Steel String X-Brace system. All I read is that they are important and useful, that people make them in all sorts of angles, sizes and shapes. Somogyi states that the X-Brace design primarily seeks to curtail Cross Dipole...

My Chladni experiments got interrupted by a garden party next door who were unhappy with my choice of music in the workshop, symphony in 453Hz!
Hopefully get a crack on investigating further this week.

Re: Saddle position
I'd be highly tempted to plug all 6 holes with hardwood. Shim off a good 3mm from the top of the entire bridge and laminate a new 3mm thick panel on it. Then rout out your saddle slot, then put in your peg holes. As they say 'cover up your mess ups.'

Re: Double V Neck Acoustic
Great work, truly good stuff.
I can’t wait to hear a review of how it sounds. I’m a little puzzled by the joining of the two soundboards along that straight line and how they might vibrate as a single plate.

Re: Help reading flamenco tap tone data
Excellent. The other ancillary benefit is that it is also a tone generator. You can plug it into your guitar amp and set it to your desired Hz level and blast away, perfect for Chladni patterns.

Re: Help reading flamenco tap tone data
Cant help with frequencies I'm afraid but recording buzz free is easy.
FFT from the app store.

There's a google Play version too.
It generates lovely graphs, allows you to store them and crucially allows you to take average reading over multiple taps.

You’re going to kick yourself that you didn’t get one earlier.
Shaping bodies, bridges, pegheads, braces, jigs, moulds and a whole host more will never have been so easy.
