Up for sale is a truly exceptional, one-owner Yamaha YEP-321S 4-valve euphonium in beautiful silver-plated finish. This instrument is approximately 50 years old (dating back to the mid-1970s), making it a wonderful vintage example of Yamaha's legendary Japanese craftsmanship. Unlike most school-rented or heavily abused student horns, this euphonium has been meticulously cared for by the original and only owner for its entire life. In fact, a professional brass repair technician recently evaluated it and stated it was "in the best condition for a used instrument he'd ever seen.“

Mechanical Condition: 10/10

• Valves: The action on all 4 pistons is lightning-fast, smooth, and snappy with excellent compression.
• Slides: All tuning slides move completely freely and pull smoothly, with no stuck joints or corrosion. All slides maintained since new with anhydrous lanoline lubricant .

Cosmetic Condition: Excellent (9.5/10).
For a 50-year-old brass instrument, the cosmetic preservation is remarkable. The silver plating is bright and highly reflective. The only minor signs of use are:

• A slight, completely normal thinning of the silver plating on the tubing directly below the valves (where the hand naturally rests), which was reviewed by a professional brass repair tech.
• Two tiny, almost unnoticeable cosmetic dings that do not affect the playability, projection, or intonation of the horn in any way.

Included:

• Original hard-shell case (fully functional and structurally sound)
• Mouthpiece
• Silver polish/anti-tarnish mitt
• Custom leather hand-tube protector

This is a rare opportunity to own a golden-era, Japanese-made YEP-321S that plays like a dream and outclasses many modern iterations. Yamaha continues to offer the same model, but not with the same quality. Perfect for a serious high school or college student, community band player, or doubling professional looking for a reliable, top-tier intermediate horn without paying brand-new retail prices. Local pick up in the Atlanta, Georgia area to avoid shipping expense is available.
