The MB-20 Valve Short C-Valve Trombone from the house of Thomann features a compact design and can therefore be conveniently carried and stored. It is equipped with three Périnet valves, which eliminate sharp bends in the wind passage to maintain the smooth flow of air. This trombone is pitched in C and serves as an ideal accompaniment for your next gig. This instrument exhibits an optimum bell size of 199.5mm and a bore size of 12.7mm. Owing to the brass construction of this trombone, it offers excellent corrosive resistance. The lacquer coating imparts radiance to the overall design.
