YAMAHA Silent Brass SB2X Euphonium

Purchased new in November 2024 and never used.
The cardboard box has only been opened, and the main unit is still in its original bag, in perfect condition.
Although it is new, the operation has not been confirmed, so it will be listed as near unused.

The product description below is copied from the sales page. Specifications may differ slightly.
Yamaha's proprietary technology Brass Resonance Modeling
Brass Resonance Modeling digitally processes the sound captured by the pickup mute to correct the tone, as if playing without a mute. It minimizes the tonal changes that occur with normal mute playing.
It also adjusts the time difference, volume, and tone of the sound returning from the instrument's bell to the player, reproducing the sound of playing without a mute.
