Yes of course, António Torres did this. The point is that the tornavoz is not so efficient and I came to the idea of this project exactly while thinking about the tornavoz. If I listen to the sound of a Stroh violin and Violon Cello on You tube I find it is surprising. It confirms what I find always...

Hi again, I will most probably make a first attempt by playing around with a good phonograph sound box. I might want trying to attach it to the bridge somehow and check out what it does. Perhaps a medium size speaker membrane could do the job also. The basic idea is to maintain the original set-up o...

Hi again, I am planning to adapt the concept of the Stroh violin to a classical guitar. I wanted to know if there are members around who are experienced with the membranes and diaphragms.

The problem is that the professor did scratch up the guitar pretty bad allready in the first few month. So the student who bought it wants i...

Hi all, I am going to refinish a cedar top which has plenty of scratches on it. I have done it before and I find this always a challenge. If you sand the scratches out this may leave some blotchy spots with different stain and I find always, when I look to a refinished top in an angel against the li...

I'm always interested to exchange some information about building parameters and this kind of stuff. I'm also a guitar player and still make some progress after 35 years. I have made some inter...
