OK, David, here we go. I got some very usefull information from Nowa Randall (http://www.randolin.com
), an American luthier.
I'm just trying to help, so don't **** me off again.
This is what Nowa wrote me: "I worked/studied production work, as well as guitar and finish work with BMB Guitarras in 1988, as well as imported their guitars into the USA from 1984-88. Jesus Marzal was primarily a finish man, and did very little luthier/wood working work. His finish work was some of the best I have ever seen, and I learned much from him. His brother-in-law Batiste Bofi was the principal luthier/designer. I can check with Batiste about Jesus working with Ramirez, as I have never heard him speak of this. I do not believe he is alive. Several years ago he was very ill."
"The way it worked in the shop was each luthier/major player in the shop had a guitar labeled and designed under their name. For instance there is a Bertrand Martin model, and he was a business owner, and something of a designer, but in no way could he be qualified to be a luthier in the full sense of the word. Jesus on the other hand, as I said was a superb finish man, and in modern shops this qualifies one to be called a luthier. He did do some work working, but not to the level or understanding of Batiste or myself. Bertrand was a guitar player as well, so his major contribution was in how instruments played. They had someone named Anacleto, who was a susperb luthier wood-worker, but he was ONLY an employee and never received any credit.There were a number of players that were friends and business associates who gave feedback on playability, as neither Jesus nor Batiste were or are players. In the time I was there I gave them much feedback and help in making their instruments more playable, though unfortunately this was near the end of the shops life. Batiste Bofi still builds several guitars a year in Xeraco."
Some internet research shows that the adress of BMB was: Senia Ferrer 6, Xeraco.
