The 105MS/105M is smaller and lightweight, allowing bands with small children to be able to march with a genuine tuba sound. Despite its smaller size, this instrument offers a surprisingly big tone. The 0.661" bore achieves the ideal balance between easy response and solid, authoritative sound, and the 105MS/105M has been designed to be easy to handle while marching. It's perfect for those facing budget restrictions as the convertible leadpipe makes it perfect for both concert or marching bands.
