Every generation has had their heros. In Bachs day it was the Haas, Ehe and Leichamschneider families, then came Michael Saurle at the turn of the 19th century.
After that we have Couesnon, Heckel, Distin and many others.
The 20th century brought Besson, White, Bach, Conn, Holton and later Selmer.
Many of you will have additional "heros". Kanstul did not make it because the business model was not sustainable without the myth Zig. The real problem is zero innovation. There was no reason to buy a Kanstul over a Bach, Yamaha, Jupiter, Getzen or other brand. Sure, they were well built and sounded OK, but that is not enough. If there had been innovation, they would have been snapped up - if nothing else for the patents (what patents?). Can you base a company on Martin Committee copies or a better Bach?
Look at the last 20 years. Yamaha has smoked Bach, Schilke and many other manufacturers. Many of the major symphony orchestra and jazz/studio musicians play Xenos. They are being used in places that no other manufacturers have been able to penetrate.
Who will miss the Kanstul brand in 10 years? Have you seen prices for used Kanstuls going up since they closed their doors?
