Conn 52H Bb/F Tenor Trombone
The Conn 52H is an intermediate-level dual bore tenor trombone featuring a Bb/F trigger attachment. Designed for students and amateur musicians, it bridges the gap between narrow and large bore instruments by utilizing a hybrid bore design for enhanced versatility across genres.

Overview
The Conn 52H represents a significant step for musicians transitioning from beginner models to professional-grade equipment. As a Bb/F tenor trombone, it includes an F-attachment trigger, which allows for expanded technical facilities in the lower register and alternative positions for improved tuning and speed. The primary characteristic that distinguishes the 52H is its dual bore construction, which is engineered to provide a specific balance of resistance and projection.
Dual Bore Design
The dual bore slide on the Conn 52H is designed to offer a unique playing experience compared to standard single-bore instruments. The initial resistance is provided by the narrower section of the bore, which aids in note stability and ease of response for the developing player. As the air travels through the instrument, the bore opens up, allowing for the resonant, larger sound typically associated with large-bore symphonic trombones. This design choice aims to provide the best of both worlds: the control of a medium bore and the power of a large bore.

Sound Character and Versatility
Because of its hybrid design, the Conn 52H is noted for its extreme versatility. It is capable of producing a broad, rich tone suitable for large symphonic orchestras, yet it maintains enough focus and agility to be used effectively in small jazz ensembles. This makes it an ideal 'all-rounder' for students who may be performing in multiple varied musical contexts throughout their academic or amateur careers.
Target Audience
The instrument is specifically marketed toward the intermediate market. This includes high school and university students who have outgrown their starter instruments and amateur musicians who require a reliable, high-quality instrument for community bands or orchestras. The dual bore system is particularly helpful for those who find the transition directly to a professional large-bore trombone to be too demanding in terms of breath support.
Market Comparison
Within the Conn product line, the 52H sits alongside other specialised instruments like the Conn 34H Alto Trombone. When compared to entry-level options such as the Grassi STB850 School Series, the 52H offers more sophisticated mechanics and a more complex tonal palette. In terms of pricing, it sits in a premium intermediate bracket, typically retailing around GBP 3480.

Frequently asked questions
- What level of player is the Conn 52H designed for?
- The Conn 52H is designed for intermediate players, specifically students and amateur musicians looking to upgrade from a beginner instrument. It serves as a bridge between student models and professional symphonic trombones.
- What does 'dual bore' mean on the Conn 52H?
- A dual bore slide uses two different diameters for the inner slide tubes. This design provides initial resistance from the narrower bore for easier control, which then expands to a larger bore to produce a bigger, more resonant sound.
- Can the Conn 52H be used for jazz?
- Yes, the Conn 52H is highly versatile and suitable for small jazz ensembles. Its dual bore design allows for enough agility and focus to perform well in jazz contexts despite its ability to produce a large orchestral sound.
- Is the Conn 52H suitable for symphonic work?
- The instrument is well-suited for large symphonic orchestras. The bore opens up to produce the large, powerful sound character required for orchestral brass sections.
- What key is the Conn 52H pitched in?
- The Conn 52H is a Bb trombone that features an F-attachment. This allows the player to access lower notes and alternative slide positions by engaging the trigger.
- How much does a Conn 52H typically cost?
- The typical price range for a new Conn 52H is approximately GBP 3480. Prices may vary slightly depending on the retailer and regional taxes.
- Which mouthpiece works well with the Conn 52H?
- While mouthpiece choice is personal, players often use options like the Bach Megatone 5G Small Shank for a richer tone or the Gear4Music Coppergate 11C for a different response. Note that the 52H typically accepts small shank mouthpieces.
- How does the Conn 52H compare to the Grassi STB850?
- The Grassi STB850 is a School Series instrument intended for beginners. The Conn 52H is a more advanced intermediate instrument with a dual bore design and higher build quality, reflected in its higher price point.
- Does the Conn 52H have an F-attachment?
- Yes, the Conn 52H is a Bb/F tenor trombone, meaning it includes a rotary valve trigger to engage the F tubing for extended range and technical facility.
- What are the benefits of the resistance provided by the 52H?
- The initial resistance from the narrow bore section helps the player with note centering and response. This makes the instrument more forgiving for developing players who may not yet have the breath support required for a full large-bore trombone.
- Is this a large bore or medium bore trombone?
- It is a dual bore instrument, meaning it incorporates elements of both. It starts with a narrower bore for resistance and opens into a larger bore for a bigger sound, making it a hybrid design.
- What other Conn trombones are related to this model?
- Related models in the Conn catalogue include the 34H Alto Trombone. While the 34H is a specialized alto instrument, the 52H is a versatile tenor instrument designed for broader use.
