Condition: Never owned. This particular clarinet has had very little playing time and appears to have been used as a display model, with no clear signs of wear from regular play. Prior to shipment, it will be professionally serviced, set up, and play-tested to confirm proper sealing, key regulation, and consistent response across the full range.
Who the Q-Series A Clarinet Is For
The Backun Q-Series A Clarinet is a professional-level, French-style Bb clarinet designed for players who want traditional ergonomics and feel with modern manufacturing consistency. It is well suited to advanced students, conservatory players, doublers, and working professionals who need reliable intonation and quick response for orchestral, chamber, wind ensemble, and commercial performance.
What distinguishes the Q-Series is its combination of classic-style playability with Backun production details such as a precision-processed bore and sculpted tone holes, inline trill keys to help manage moisture-related issues, and upgraded pad and silencing materials for quieter, more controlled key action. The included Lumiere barrels (65 and 66) and Lumiere bell provide additional flexibility in setup and response across registers.
Common Questions About The Backun BCLAQC-GKG
Is the Backun Q-Series suitable for professional use?
Yes. The Q-Series is built as a professional A clarinet, with features aimed at consistent intonation, reliable response, and durable keywork, making it appropriate for conservatory study and professional performance.
What does “French-style” mean on this clarinet?
In this context, French-style refers to a traditional clarinet feel and playability profile familiar to many modern Boehm-system players, paired with Backun’s precision manufacturing approach to the bore and tone holes.
What sizes are included with the two barrels, and why does that matter?
This clarinet includes two Backun Lumiere barrels in sizes 64 and 65. Having two lengths helps players fine-tune pitch and response to match different mouthpieces, reeds, and ensemble tuning standards.
