A one-piece bell has an axial (lengthwise) seam, making it a continuous extension of the instrument's material. This results in pure, uniform resonance and superior tone.

The bell is 8 11/16" in diameter. The larger bell in combination with other design improvements, produces a singing, colorful open sound with a projecting solid core.

The open wrap has a more open feel and quicker response while using the F attachment.

Having a narrow slide results in a faster slide technique allowing the player to get around the horn easier.

Eliminating sharp turns in the crook will open the feel and response of the instrument.

The unique slide lock design on all Yamaha trombones keeps the slide locked in place and keeps it from accidentally falling.
