Configure your own Adams trombone

Some people like a warmer sound. Some do not. Some people have huge lung capacity. Some do not. Some people need more playing resistance. Some do not. These are extremely personal factors that can affect an instruments design.

The Adams instrument builders like to go beyond expectations. With an in-house development and production, this means that we can fully customize your instrument according to your personal preferences.

Besides the standard configuration, Adams trombones offer a number of custom adjustments including different bells and slides to meet your personal playing style.


Every Adams trombone has a unique one-piece hand-hammered bell, made out of yellow brass, gold brass, or sterling silver. No matter which material you choose, these bells are unique, carefully made, and each give the musician different expressive possibilities.

Yellow Brass

A yellow brass bell is always a smart choice. It speaks very directly and offers a consistent and refined sound that in general suits every type of player.

Gold Brass

A gold brass bell colors very easily in terms of sound. In addition, the sound also mixes very easily, a quality that is very important for many musicians. Gold brass is often chosen as the perfect compromise between brass and red brass. The material contains about 85% copper.

Red Brass

Our red brass bell offers a larger and warmer sound compared to the yellow brass bell. It makes the bell very suitable for more powerful orchestral playing.

Sterling Silver

This bell offers a very rich and elegant sound that is a bit brighter compared to the other bells. The Sterling silver bell is very precise and makes articulation easier, making it an excellent choice among soloists.


All Adams slides have chrome plated nickel silver inner slides to guarantee the best possible hand-slide action. To get an instrument that fully meets your personal expectations, we offer a variety of slide options.

Yellow brass offers a lively, and centered tone. Nickel silver is known for its broader and more powerful playing character. The lightweight slides ad a bit of energetic response and brilliance to the tone.
