New. This instrument has been professionally serviced, set up, and play-tested to confirm proper slide function, valve alignment, and consistent response through the full valve combinations and range.

Who the STBQ38YR Contrabass Trombone Is For

The STBQ38YR is a European-tuned F/D/Bb/Ab contrabass trombone designed for advanced and professional trombonists who need contrabass power with controlled response and reliable valve technique. Its independent valve system favors using each valve on its own (rather than a dependent configuration), helping players avoid extended slide positions and move through technical passages with an efficient blend of valve and slide technique.

The .590 in bore and 10.5 in detachable-flare yellow brass bell are built to produce a rich, resonant tone with focused projection and a vibrant core. This configuration supports the agility required for modern repertoire and complex orchestral writing while maintaining the balance and mechanical consistency associated with S.E. Shires builds.

Common Questions About The S.E. Shires STBQ38YR

What does European tuning mean on the STBQ38YR?

European tuning on the STBQ38YR refers to an independent valve system in F/D/Bb/Ab where each valve is intended to be used independently, making common passages less dependent on extended slide positions and improving technical agility in modern orchestral and solo literature.

What is a Rotax Rotary Valve?

A Rotax valve is a specialized rotary valve design used on high-end brass instruments that helps bridge the gap between European and American tuning concepts. Its defining feature is a distinctive internal rotor geometry that begins relatively flat and transitions into an expanding shape, reducing air turbulence and allowing for smoother airflow back into the instrument. In practice, Rotax valves are prized for their light, fast action and the “solid core” they provide in the low register, a quality many players consider essential for contrabass performance. They also offer a notably centered and secure response, often feeling more stable than axial-flow valves while retaining quickness. As a result, Rotax valves combine the free-blowing efficiency of modern valve designs with the tactile feedback and clarity associated with traditional rotary systems.

What is the advantage of the detachable-flare bell?

The 10.5 in detachable-flare bell improves portability and supports flexibility in feel and response while retaining the core tonal characteristics of a two-piece yellow brass bell.

Fresh and clean
I'm not fully sold on blackhead removal, but I do like that it cleans dead skin and leaves a fresh, clean feeling. Will try for a couple more weeks to see if it makes any difference

Brighter, smoother skin within a week
This Peeling Shot Glow Rice Ampoule Duo has easily earned a permanent spot on my bathroom shelf. The day and night combo really does make a difference — the daytime ampoule brightens and smooths, while the nighttime formula deeply hydrates and helps my skin recover overnight. After about a week, I noticed a natural glow that even my partner commented on (and that’s saying something).The rice-based formula is gentle but still effective — it exfoliates without irritation, even on sensitive skin like mine. It has a clean, light scent and a silky texture that absorbs fast without feeling sticky. I use it on my face and occasionally on rougher areas like elbows and neck, and everything feels softer and more even-toned.It’s refreshing to find a product that delivers real results without harsh chemicals or heavy fragrances. The dual bottles also look sleek and keep my routine simple — one for day, one for night, done. I currently recommend this product. If anything changes I will update my review accordingly.
