This Olds P-22 single valve bass trombone is a rare and collectible model famously associated with George Roberts, the legendary low brass voice of the West Coast sound. Roberts played this exact model for much of his career, and when asked why he never switched to a dual-valve setup, he simply replied: “I always got along fine with just one.”
Made in the early 1970s, this instrument features a 9" rose brass (also referred to as gold brass) bell, a .565 bore, and a nickel silver handslide. The rotary valve system functions smoothly, and the horn has been fully serviced, including a slide realignment. Tonally, this trombone produces the kind of round, sweet sound that made Roberts a household name in orchestral pops and big band sections.
Cosmetically, it shows moderate lacquer wear in grip areas and some light aging on the bell, consistent with its age. That said, there are no dents or structural issues, and the horn is fully gig-ready. The overall condition is excellent for a professional player or collector seeking a historically significant single-valve bass.
Because of its balance and ease of response, this model makes an ideal choice for tenor trombonists looking to double on bass without committing to the weight and resistance of a modern in-line system. It’s also perfect for players focused on jazz, pops, or pit work where agility and color are more important than extended valve range.
Includes the original Olds P-series case in clean condition.
FAQ
What makes the Olds P-22 different from other single-valve bass trombones?
The P-22 was built specifically for and endorsed by George Roberts. Its design prioritizes warmth, tonal depth, and clean slide geometry. Unlike heavier commercial bass trombones, it retains a classic California-style feel with effortless response.
Is a single-valve bass still practical in modern performance?
Absolutely—particularly in jazz, commercial, and Broadway settings. The F-attachment gives access to low F, E, Eb, D, Db, and C. While low B-natural isn’t as easily accessible without a second valve, George Roberts famously pulled his F slide all the way out to reach it. It may not work as seamlessly as a modern in-line system—but who can argue with George Roberts?
How does the gold/rose brass bell affect the tone?
Gold brass contains more copper than yellow brass, which results in a warmer, broader tone with fewer upper overtones. When paired with the .565 bore and nickel silver slide, the sound feels round and rich with a quick response.
