Overview
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 was known for achieving remarkable results with a single-valve setup.
Made in the early 1970s, the instrument features a 9" rose brass (gold brass) bell, a .565 bore, and a nickel silver handslide. This combination produces a tonal profile that is warm, round, and highly responsive—well suited for jazz, commercial, and orchestral pops playing.
This example has been fully serviced, including slide realignment, and remains structurally sound. The rotary valve system functions smoothly, and the instrument maintains the characteristic ease of response that defines this model.
Player Perspective
From a playing standpoint, the Olds P-22 offers a different experience compared to modern dual-valve bass trombones.
The response is immediate and open, with less resistance than many contemporary in-line valve systems. This makes the instrument especially appealing for players who value agility and tonal color over extended low-range capability.
The rose brass bell contributes to a broader, more relaxed sound, while the .565 bore provides enough depth to support bass trombone repertoire without becoming overly heavy in feel.
For tenor trombonists doubling on bass, the P-22 presents a natural transition point—offering the weight and sound of a bass trombone while maintaining a level of flexibility that feels familiar.
Questions Trombone Players Often Ask
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, offering a more agile and responsive feel than many heavier bass trombones.
Is a single-valve bass trombone still practical today?
Yes—particularly in jazz, commercial, and Broadway settings. The F-attachment provides access to low F, E, Eb, D, Db, and C. While low B-natural is less accessible without a second valve, many players—including George Roberts—used slide extensions to reach it when needed.
How does the rose brass bell affect the sound?
Rose (gold) brass contains a higher copper content than yellow brass, producing a warmer, broader tone with fewer upper overtones. Combined with the .565 bore and nickel silver slide, the result is a round, rich sound with quick response.
