Re: Measuring top and back frequencies while voicing

Jim, Brian Burns told me that when taping a back on it was fairly close to the result of gluing on the back, well, at least it only raised the back mode by about 5%. So it seems to work for a temporary attachment so the guitar can be opened and the bracing adjusted. In any case, it would be nice to ...

Re: Measuring top and back frequencies while voicing

So after thinking about this for quite some time, it seems that an approach to the falcate type soundboard that the braces could be attached with the CF tow underneath and glued to the rim.

I will make an attempt and see ho...

Re: Measuring top and back frequencies while voicing

Another quick question. If a free plate is held in a fixture where the edges are constrained, is there any correlation to what the top does once it has been installed on the guitar itself? And does anyone think that it would be possible to build a jig that mimics the internal sound chamber but allow...
