Reading the amati clarinets posts from a year ago it would seem the horns are needing tech adjustments for certain players. Not sure if that is like adjusting the seat in your car after someone else drives it or a complete rebuilt model? Snagged an 25 year old wood Amati Kraslice Special off eBat that was sitting in a closet for 25 years after one six month band class and never played again. It's in the mail and started to look for info on the horn and wondering if adjustments are like a car seat or a total rebuilt engine? Parents who's children loose interest should donate the horns to the school and like a car keep them serviced. Untouched for 25 years???
