Used 2025 Yamaha YTR-8330EM Eric Miyashiro Bb trumpet in lacquer, very good condition. This is an excellent lightweight, big-bell trumpet for all-around playing but especially suited to commercial music. The main tuning slide has an L bore, the valve slides have an ML bore, and the pistons have an M bore, so despite the big bell you get a ton of control, and the French bead on the bell gives you excellent feedback so you can hear yourself in loud situations. We gave it a professional cleaning and precision valve alignment; the valve action and compression are both like new, though there's some evidence of very minor repairs to the bell flare and tail. There are also a few small scratches here and there and a small nick in the lacquer on the leadpipe, as well as a small blemish on the bell bead. These are all very minor and do not affect playability in any way. Comes with Kaces case in excellent condition.
FROM YAMAHA:
New design leadpipe and mouthpiece receiver

Thanks to just the right amount of playing resistance, high notes are easier to reach and overall control is notably improved.
Step bore (ML)
A step bore* (ML) design has been adopted to achieve optimum playability and tonal consistency throughout the instrument’s range.
*The main tuning slide has an L bore, the valve slides have an ML bore, and the pistons have an M bore. This helps to maintain smooth, consistent playability when all three valves are open or fingered in any combination.
Phosphor bronze parts (Bottom caps / 3rd slide stopper)

To achieve optimum tone and playability, numerous prototypes were made using different materials of different weights. The result was the adoption of phosphor bronze bottom caps and slide stopper for the first time in the Yamaha trumpet lineup. The new parts contribute to a brilliant high register as well as greater harmonic richness in the middle registers.
Main tuning slide brace

A unique tuning slide brace shape that reduces resistance when compared to conventional braces evens out resonance by minimizing variations in playing feel and resistance. The position of the brace has also been revised in the new model, to achieve optimum overall playability.
Bell

Large one-piece bell (134.4mm, 5-1/4") provides poweful sound and quick response.
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.
