YAMAHA TR-EM1 Eric Miyashiro Model Old Model Trumpet Mouthpiece I was quite fond of it, but I'm selling it due to various circumstances. Take this opportunity. Supervised by a top player: Signature model of Eric Miyashiro, a high-note hitter who is the pride of Japan. Features: With a very shallow cup and thin rim, it achieves overwhelming high-tone control and a brilliant sound. Size: Inner diameter 16.02mm. Ideal for lead playing, pops, and high-note playing in wind bands. Playing feel: The quick response, where breath efficiently turns into sound, is attractive. Switching from other trumpets is also smooth.
