A large-bore tenor designed to serve as an alternative to artist models, the TR680 allows the student to bridge the gap between small-bore and large-bore instruments. It is highly recommended as an introduction to the bass trombone, as it offers enough resistance for the student to produce a full sound and assists in maintaining intonation. The unique “flat wrap” F attachment provides an extra measure of protection against damage.
