Karr-Koussevitzky
The Karr-Kousevitzky bass or Amati bass is a famous double bass previously belonging to Serge Koussevitzky and Gary Karr. Now generally referred to as the Karr-Koussevitzky rather than the Amati; until recently, the bass had been attributed to the Amati brothers, but now it is generally believed to have its origins in France. It is renowned for its tonal quality in solo music but is considered to be difficult to play.
