The BTS E/F/G trumpet, the predecessor to the current Master trumpet, was a true milestone, offering three different tunings in a single trumpet, solutions unthinkable until then.
An instrument with three fully functional tonalities at a maximum performance level, a powerful tool for the orchestral musician and an interesting complement to the soloist.
