8 Things to Know When Buying a Used Trombone: A Simple Guide

by Madonna

Purchasing a used trombone can be a cost-effective way to acquire a quality instrument, but it’s essential to approach the process with caution. Unlike buying a new trombone, where you can rely on the reputation of the manufacturer and consistent quality control, purchasing a used instrument requires a more discerning eye. In this guide, we will explore the key factors to consider when buying a used trombone to ensure you make an informed and satisfactory purchase.

1. Condition of the Brass:

The first aspect to assess is the overall condition of the brass. Examine the instrument for dents, scratches, and signs of wear. Small dents may not significantly impact playability, but large or numerous dents can affect the sound quality and playability of the trombone. Look for discoloration, as this could be an indication of poor maintenance or exposure to harsh conditions. A well-maintained instrument will likely have a smoother, more consistent appearance.

2. Slide Action:

The slide is a critical component of a trombone, and its smooth action is essential for playing ease and accuracy. Check the slide for any dents, bends, or rough spots that could impede its movement. Move the slide back and forth to ensure it glides effortlessly. If the slide is sticky or uneven, it may need professional attention, potentially impacting the playability of the instrument.


3. Valves and Rotors:

If you are considering a trombone with valves or rotors, carefully inspect them for wear and tear. Ensure that the valves move freely without sticking or grinding. Listen for any unusual sounds during valve movement, as this could indicate mechanical issues. Valves that do not seal properly can affect the instrument’s intonation and playability, so it’s crucial to assess their condition thoroughly.

4. Check for Leaks:

Inspect the trombone for air leaks, particularly around the joints and tubing. A simple way to test for leaks is to assemble the instrument and blow air through it while covering all the openings. If you notice any hissing sounds, it could indicate leaks that need to be addressed. Leaks can compromise the instrument’s tonal quality and playability, so it’s crucial to address them before finalizing a purchase.

5. Evaluate the Mouthpiece:

The mouthpiece is a vital component that significantly influences the trombone’s sound. Check for any dents, scratches, or signs of wear on the mouthpiece. Additionally, inspect the shank to ensure it fits securely into the lead pipe. A well-maintained mouthpiece contributes to better playability and sound production.

6. Consider Brand Reputation:

While buying a used instrument may not allow you to choose a brand-new model, it’s still essential to consider the reputation of the brand. Established and reputable manufacturers often produce instruments with consistent quality. Research the brand and model of the trombone you are considering to ensure it has a history of reliability and positive reviews from musicians.

7. Seek Professional Advice:

If you are unsure about the condition of a used trombone, don’t hesitate to seek the advice of a professional. Bring the instrument to a music store or consult with a knowledgeable musician or music teacher. They can provide valuable insights into the instrument’s condition and help you make an informed decision.

8. Check for Modifications:

Examine the trombone for any modifications or repairs. While some modifications may improve the instrument, others could affect its playability and value. Look for signs of soldering or other alterations and inquire about their purpose. Modifications done by a skilled technician may enhance the trombone’s performance, but it’s crucial to be aware of any changes made to the original design.


Buying a used trombone requires careful consideration of various factors to ensure you get a quality instrument that meets your needs. Assessing the condition of the brass, slide, valves, and other components is crucial. Additionally, considering the reputation of the brand, seeking professional advice, and checking for modifications can contribute to a successful purchase. By taking the time to thoroughly inspect a used trombone, you can make a confident decision and enjoy the benefits of a cost-effective yet high-quality musical instrument.
