2016 Yamaha YTR-8340 EM Miyashiro Bb Trumpet

This is a first generation YTR-8340 EM Bb trumpet.  It is estimated to be approximately 2016 production.

This model was developed in collaboration with Eric Miyashiro.  It features a one piece yellow brass 5 1/4" bell and a lightweight body.  It is a medium bore, but with large bore valve slides.

This trumpet shows a little wear to the lacquer on the valve casing.  The leadpipe has been replaced with a Yamaha supplied replacement as the original leadpipe suffered from some pre-mature red rot and Yamaha provided a replacement leadpipe.  The new pipe has been expertly installed and lacquered to match the trumpet.

Valves are fast and smooth; slides are smooth; and valve compression is excellent. 

 Features:

Multi-bore

When the piston is not depressed, the trumpet has the same bore structure as a Bb trumpet as M bore size. However when the piston is depressed, the unique “multi-bore” structure reduces the difference in back pressure by passing through the L bore valve slide.

French Bead

Unlike traditional methods where a round rim is used in curling, French bead is an extremely advanced technique that matches the curling to the shape of a semi-cylindrical rim and is characterized by improved feedback of sound to the performer.

Side Seam

Side seaming is the process of placing the connection point on the lateral valve casing side in contrast to the conventional method of placing the connection point on the lower side of the bell. Side seam trumpets are characterized by a more open vibration.
