I only produce up to 6 a year. And even more amazing is that I use no power tools to produce these instruments, because I prefer to utilize traditional lutherie skills.
I cook the wood to remove impurities, plane the wood by hand to smell and to touch, dry the wood for years in the sun - not in ovens, and I cut with lutherie knives, not jig saws. This process is obviously slower, but I believe it produces world class instruments.
