C trumpets are at the heart of Schilke's culture, and the new HD series of trumpets were developed to offer a darker core of sound with superior articulation clarity. Completely new design elements include a square-shaped tuning slide bow and a re-designed mouthpipe taper and receiver. In addition to these features, the construction and design of the HD bell creates a solid, secure feel with incredible tonal depth. These new models are recommended for classical as well as jazz/commercial players alike. HD trumpets are offered in silver plate, 24K gold plate, raw brass or lacquer finishes.
