The Conn 71H is a rarely seen single trigger bass trombone built in the 1970s, retaining all original parts and lacquer in exceptional condition. This example features a lightweight 9.5" yellow brass bell with an unsoldered rim, giving it a fast, vibrant response and open resonance. The bell section includes a standard rotor with a semi-open wrap, contributing to its flexibility and clean transitions between registers.
The handslide is classic Conn construction, with yellow brass outer tubes, a nickel silver endcrook, and a Remington leadpipe. The inner slide tubes are as close to flawless as you'll find—100% plating, no wear, and superior alignment. It plays without tension and speaks quickly across the full range.
Tonally, this horn is alive. Trigger notes like D, Db, and low C speak easily and with fullness, and low C at FFF truly roars. Despite being a bass trombone, the horn feels remarkably light—not much heavier than an 88H—and will feel instantly familiar to any large bore tenor player looking to step into bass.
This model works with any standard bass trombone mouthpiece, though it’s optimized for a Remington taper. These are still made today by Schilke and Bach. While not included, they're easily sourced.
The original Conn case is also in excellent condition and completes this rare find.
Is the Conn 71H a good option for players moving to a single-valve bass trombone?
Yes. The Conn 71H is a rare example of a lightweight, single-valve bass trombone that plays with exceptional ease and clarity. It offers the full tonal range needed for orchestral and ensemble bass parts—including low D, Db, and C—without the added complexity or weight of a double-valve setup. This makes it an ideal choice for tenor trombone players upgrading from models like the 88H or for advancing students seeking their first professional-level bass trombone. Its compatibility with standard Remington taper mouthpieces also ensures a smooth transition for players already familiar with vintage Conn designs.
