Yamaha 671 Review

The Yamaha 671 is Yamaha's professional Geyer-style double horn, introduced as the successor to the older 667 line. It keeps the Yamaha strengths that players expect: clean construction, reliable intonation, fast valves, and a focused sound that is easier to live with than many less consistent factory horns.

Compared with the 667, the 671 was designed to project with more authority. Yamaha used a slightly heavier bell and thicker bell wire, which gives the horn more center and stability. Some players may miss a little of the color and nuance they associate with handmade horns, but the 671 makes a strong case for players who want a professional horn that responds predictably day after day.

One of the biggest reasons to consider the 671 is the valve feel. Yamaha valves tend to be quick and quiet, and players coming from older or less refined horns may notice that fast passages feel easier right away. If you choose a detachable-bell version, check the case situation before buying; Yamaha cut bells can sit taller than some common case designs expect.

The Yamaha 871 is the custom version in this family. It shares the same general direction but adds custom-shop construction details, including gold-brass inner tubes and a hollow fourth rotor.
