New old stock-The Roy Benson AT201 is brilliant for someone looking to start playing the alto trombone. An included mouthpiece means that you can start playing right away. This instrument is lightweight at only 0.95 kg, and a form-fitted case with rucksack assembly makes transporting your new AT201 simple. You can keep all your sheet music in one place with the external pocket too.With a dual bore configuration (12.2 mm and 12.4 mm), this alto trombone plays with the ease of a smaller but the sound of a larger bore. This means that you get a free-blowing experience with the full depth of tone. The 190.5 mm yellow brass bell provides clear projection and a bright tone. Nickel silver inner and outer slides are durable, resistant to wear and move smoothly while chrome plated inner slides aid in the flawless action. A lacquer finish keeps your instrument looking beautiful and protecting it from tarnishing. If you're looking for a new challenge, the AT201 is a perfect choice!
