Berkeleywind Professional Rose Brass Bass Trombone – Double Independent Rotors

The Berkeleywind Bass Trombone is designed for serious players seeking professional performance at a far more approachable price. Featuring a double independent Bb/F/Gb rotor system, this instrument offers exceptional range and flexibility. The first rotor is tuned to F, the second to Gb; engage both and you unlock D in first position—expanding your musical options and making difficult passages easier to navigate.

This trombone is built with heavy-wall construction for a rich, resonant tone, a .563" large bore for powerful projection, and a hand-hammered 9½" rose brass bell that delivers a warm, dark sound with excellent projection. The lightweight chrome-plated nickel hand slide ensures smooth, responsive action, while the gold brass leadpipe and large shank receiver support a commanding, full-bodied tone.

Many players first see the price and wonder if a professional bass trombone can really cost this little—but compare it to Yamaha’s YBL-613H or YBL-622 (well over $3,000), and you’ll see why musicians are impressed. One of my friends owns the Yamaha 622; we’ve played side by side, and we honestly can’t tell a difference in tone or response.

This instrument is crafted by Berkeleywind in China, where trombone manufacturing has transformed—once seen as “cheap,” now producing world-class instruments. We believe this is the best rose brass bass trombone coming out of China today: warm, powerful, and built for players who demand quality without overpaying.
