This O'Malley F Contrabass Trombone is in like-new condition, purchased new by a professional player and played for a single recording session. It is a modern large-bore contrabass trombone built in the style of the Thein Ben Van Dijk model, with a broad, open feel and deep, orchestral tone. This is a true contrabass trombone in F, not a bass or step-up model.
It features:
.590 bore for exceptional low register clarity
Inline rotary valves (F/D/BB♭ tuning setup)
10.5" yellow brass bell
Standard large shank receiver
Smooth slide action with excellent alignment
Lightweight case with zipper closure included (clean and protective)
All mechanisms — including valves, slide alignment, and tuning rotors — were carefully tested and function as intended. It plays accurately across the full F contrabass range and appears in exceptionally clean, near-new condition, with no visible wear or damage.
This is an ideal choice for players who need contrabass capability without investing $10K+ in a custom European build. Whether for orchestra, chamber ensemble, or studio work, this horn offers performance-level response and tone at a much more accessible price point.

Is this a real contrabass trombone or just a large bass?
This is a true F contrabass trombone — not a bass trombone with oversized specs. It plays an octave below the tenor and covers the contrabass role in orchestral or contemporary literature. The bore size, valve setup, and bell dimensions are all designed for authentic contra use.
Who is this best suited for?
Ideal for professionals, pit players, or university musicians who need access to contrabass range without the commitment to a high-end custom horn. Also perfect for experienced bass trombonists wanting to double into contra.
Is it made by O'Malley or rebranded?
This model is part of the well-known Jinbao stencil family — built by one of the major factories in China and distributed under several names, including O'Malley, Schiller, Wessex, and others. The spec is consistent with the Thein-inspired F contra design that has gained traction in the U.S.
