This Concertmaster was constructed entirely in Masterworks workshop in Bennington, Oklahoma. At the time Russell Cook was seeking to learn how to build my instruments for me. Seemed like a good idea until he decided to go his own way. This Concertmaster has alot of Abalone Inlay, a Cable Drive Damper System, Triple Laminated Edge binding and End Rails. It weighes in at 16lbs 14oz. It spans 4 Octaves with 3 1/2 being fully chromatic. It comes with a Song of the Wood case, hammers, tuning wrench and battery powered chromatic tuner!
