I was wondering where you learned to design musical instruments? I see on the zachary music site, the zeus line includes everything from saxes to trombones. And you handmake guitars! After reading the reviews of the G/O trumpets, I know they're quality instruments, and certainly designed by a knowledgable player. Do you play all these instruments? Is there a collaboration between you and other designers? Thanks for the answers! Take care, Ash PS, Where does one go to learn instrument repair? Is it all apprenticips (spelling!)?
