Pre-Owned Yamaha YBL-613G Professional Dependent Double-Rotor Bass Trombone - Gold Brass Bell (Ex-USAF)
We have an absolute low-brass classic on the bench today. The Yamaha YBL-613G is celebrated as one of the most reliable, warm, and balanced bass trombones from Yamaha’s golden era of Japanese brass manufacturing. Long favored by big band anchors, pit pros, and collegiate players, the 613G is renowned for its easy playability, agile response, and singing acoustic core.
The standout feature of this horn is its resonant 9.5-inch gold brass bell ("G" designation), which lends a wonderfully deep, dark, and enveloping tone that anchors large ensembles without turning harsh at extreme dynamics. Configured with a traditional dependent Bb/F/Eb double rotary system, the valve wrap is uniquely compact and balanced—tucking neatly within the chassis profile so only a small portion extends past the main tuning crook. This geometry delivers an open, responsive blow while keeping the instrument exceptionally well-balanced in the hands.
Bearing serial number 201726, this horn comes to us with authentic military ensemble pedigree (ex-USAF). It displays honest cosmetic lacquer wear and surface marks from active professional service, but beneath the cosmetic character, it is structurally rock-solid with smooth, quick slides and tight valve compression.
