Independent shopping perspective
The Korena take
Giardinelli's GTR-300 is a Bb trumpet made for students developing toward intermediate playing. Its rose-brass body, leadpipe, and 4.8-inch annealed bell are paired with a .460-inch medium-large bore and lacquered body and tuning slides. Stainless-steel pistons handle the instrument's valve work, while the first-valve thumb saddle and adjustable third-valve stop address slide handling. A mouthpiece and molded ABS case come with the trumpet, backed by a five-year warranty.
