Getzen 300/400 Series Instruments are well known for their quality and durability and the 351 Trombone is no exception. It is built to offer the quality the player wants and the durability the player needs. It features chrome plated, nickel silver inside slide tubes that have been barrel shaped to provide the fastest possible action. 351 Trombones also offer heavy nickel silver outside slide tubes. This gives the instruments the extra level of durability often needed in a classroom setting. 351 Trombones offer hand spun, yellow brass bells with wire reinforced rims.
