• One-piece brass 9-1/2″ bell
• Key of Bb/F/Gb
• Traditional rotor system
• Open F-attachment available
• Yellow and rose bell finishes are available
• Lacquer finish
• Chrome-plated nickel silver inner slide

Overview

The Vincent Bach 50B3 is a bass trombone made in America under the 100 years brand. It features inline independent double rotor attachments, adding the standard F on the first valve and Eb/G on the second valve. Open F wrap is also available to remove some bends for a freer-blowing trombone. The large bore of the instrument provides a clear and projecting sound, ideal for both symphonic and solo performances.

Bach 50B3 features a hand-hammered bell that was created by folding and joining metal, then repeatedly hammering it with a mallet to give it a flare shape. This process adds a unique sound and quicker response to the instrument. Although it may come at an extra cost, you may feel that the sound quality and clarity are improved.

Bach Stradivarius series bass trombone comes with a traditional mouthpiece that offers excellent response. It has a well-made and comfortable rim with a large diameter that requires a good amount of air and embouchure strength.

This mouthpiece is ideal for smaller ensembles as it provides a good balance between tenor and bass without making too much of a “fat” sound. However, it does not require as much air and embouchure strength as a full-sized bass trombone mouthpiece.

What Features Consider To Buy Perfect Bass Trombone As Bass Trombonist

As a bass trombonist searching for the ideal instrument, you should take into account certain factors such as the key, weight, price, and brand. Bass trombones are generally available in different configurations that determine the range of keys playable on the instrument, affecting the notes and slide positions.

A bass trombone typically comes in the key of Bb/F and can have additional attachments such as Gb, Eb, D, or open F to provide a wider range of notes and flexibility. It can be configured in three ways: single rotor, double dependent rotor, or double independent rotor. A one-valve bass trombone allows for variations in key, such as Bb (when open) and F (when the axial flow valve is engaged).

If the tuning is the same, using both dependent and independent valves will result in the same outcome. Specifically, in F/D, C, and B notes are played in 4th and long 5th. In the independent valve system, playing open gives Bb, the triggered one valve gives F, engaging both the first valve and second valve produces Eb, and playing with only the second valve engaged results in G.

Next, consider the weight of the instrument. Heavier instruments can be more difficult to maneuver but tend to have a richer, fuller sound. Lighter instruments are easier to carry and may produce a brighter tone. When you choose two valves trombone over a single-valve one, you also make it heavier and harder to practice and perform. Therefore, ensure that you are physically prepared before you opt for an advanced bass trombone or even a contrabass trombone.

If you are still struggling with trombone theory, you might find using the Trombone Slide Charts we mentioned in our post helpful. They are available for download and printing and can be utilized whenever you need them.

When buying a new bass trombone, it’s important to consider the manufacturer’s reputation and product warranty. Quality assurance is crucial in the selection process, but price is also a factor. It’s important to find a balance between cost and quality.

Is It Hard to Switch to Bass Trombone from Tenor Trombone?

The good news is that doubling tenor and bass trombones is not overly difficult. Since both instruments use the same slide positions, the basics of playing are mostly transferable. That said, the bass trombone requires more air to sound its notes properly, so breath control will be an area you’ll need to work on.

The bass trombone is much bigger and heavier, so physical strength and endurance will, of course, also be important. Practice playing both instruments in tandem to make the transition as smooth as possible. This will help you gain familiarity with the unique characteristics of each one. You can easily switch from tenor trombones to bass trombones with patience and dedication!

Conclusion

In the world of bass trombones, finding a reliable and high-quality instrument is crucial for any serious player. We understand the importance of having an instrument that helps you be confident in your ability to play your best. These best models for the year 2025 have been carefully chosen based on their exceptional sound quality, durability, and overall performance.
