Who the Q-Series Bass Clarinet Is For

The Backun Q-Series Bass Clarinet is a professional Bb bass clarinet with a low-C extension designed for players who need consistent intonation, stable response, and a warm orchestral color across the full range. It is a strong fit for advancing players stepping up from school or intermediate instruments, as well as working professionals who want a top-tier workhorse with modern ergonomics and a dependable low register.

The Q-Series platform emphasizes an even scale and centered pitch, including reliable throat tones and a clear upper clarion supported by a double-vent register mechanism for a smooth break. Cocobolo contributes a rich, focused core with quick articulation and refined overtones, while the low-C range is built for confident sub-register response and stability. The gold-plated posts add premium visual detail and additional corrosion resistance in high-contact areas, paired with blued needle springs and a clean, fast mechanism for comfortable, precise handling.

Common Questions About The Backun Q-Series

Is the Backun Q-Series Bass Clarinet suitable for professional orchestral and wind ensemble playing?

Yes. The Q-Series is designed as a professional-level bass clarinet with an even scale, stable intonation, and a resonant core that carries in large ensembles while staying clear for solo and exposed passages.

What does “range to low C” mean in practical terms?

Range to low C means the instrument includes a low-C extension key system, allowing you to play chromatically down to written low C. This expands repertoire options and supports a more complete bass line in orchestral, band, and pit settings.

How does cocobolo affect tone and response compared with other materials?

Cocobolo is valued for a rich, focused tone with refined overtones and quick articulation. Players typically choose it when they want a warm, orchestral color with clear center and strong projection without an overly edgy upper register.
