After having repaired violins (12), guitars & basses (5) and mandolins (2) during several years, I started to repair amplifiers (2) and a "Leslie" (1976 Elka rotary speaker).

Then I made a midi accordion and midi controller for drawbar organ. Still building a standalone rotary speaker taken from a Farfisa organ. Lately, I built in all 4 electric guitars and the fifth project has already started.
