Description
Yamaha YFH-631G Flugelhorn S/n 458175. This exact configuration is highly regarded by musicians and brass ensembles around the world.
This particular horn is in perfect condition with no dents, dings, or trauma. Comes with original Case and Mouthpiece.
- Model: Yamaha YFH-631G (Professional Series Bb Flugelhorn).
- Key Feature: Includes a mechanical 3rd valve slide trigger, which is essential for adjusting on-the-fly intonation on notes that naturally run sharp or flat.
- Bell Material: Gold brass with a bright silver plate finish, which yields a gorgeous dark, warm, and broad mellow sound.
- Bore Size: 0.433″ medium bore. This slightly larger size makes it the ideal “doubler’s” horn, allowing for an easy physical transition to and from a standard trumpet.
- Mouthpiece: Comes with the standard Yamaha FH-11F4 Mouthpiece, popular for its medium 16.46mm inner rim diameter and unique “U” cup that provides excellent endurance and a smooth attack.
- Storage: Includes the premium Yamaha FHC-6310 Hardshell Case.
This horn was manufactured in
Japan between the
late 1980s and mid-1990s.
- The 6-Digit Numbering System: Yamaha used 6-digit serial numbers starting with
4xxxxx specifically during the late 1980s and through the 1990s.
- Production Context: The
YFH-631 line itself was launched in the 1970s, but early models lacked the 3rd valve trigger. The trigger configuration became standard on the assembly lines during the mid-to-late 1980s transition.
- The “Made in Japan” Era: A serial number sequence in this range (
458175) points directly to Yamaha’s legendary Toyooka factory in Hamamatsu, Japan, long before some production lines shifted to other regions. Instruments from this era are highly valued by players for their precise Japanese engineering and durable alloy construction.
