Yamaha YBL835 Xeno Bass Trombone

The YBL835 has evolved to deliver the power and performance that modern music demands. It has an open playing feel and produces rich, authoritative tone that responds ideally to player control. The YBL835 is also the first Yamaha custom bass trombone to feature a detachable hand rest for significantly improved operation.

Slide Receiver: Previous models included an internal protrusion in the slide receiver that was designed to provide optimum playing resistance and consistent tone. The YBL835 does away with this design element, making possible to deliver higher volume, powerful sound, and generally enhanced playing response.

Mouthpiece Receiver: The depth at which the mouthpiece fits into the receiver has been reduced slightly, giving the mouthpiece more freedom to resonate. The result is a more flexible playing feel and easier control.

Rotor Shape: The rotary valve port shape has been modified to increase the volume of the valve tube, allowing greater breath flow for more powerful sound.

Lever Action: The level action had been upgrade with a shorter stroke that affords improved operability. Other refinements include a double torsion spring that contributes to consistent lever operation, and double ball bearings that reduce the need for maintenance and make maintenance easy when it does become necessary. The shape of the 1st lever cover has been changed to better fit the player's hand, and the angle of the 2nd lever finger plate is adjustable to precisely match the player's hand size. 

Detachable Hand Rest: The first detachable hand rest ever to be provided in a custom bass trombone significantly reduces strain on the player's hand. This allows steadier hold on the instrument, so the player can concentrate more fully on the music.

Gold Brass Main Tuning Slide: Both the YBL835 and YBL835G feature a gold brass main tuning slide that contributes to broader, rich tone.
