The Yamaha YSH411 Sousaphone
Possibly the best Sousaphone around today
Yamaha has done extensive research in developing an improved marching low brass instrument. Upon examination you will find many of the same features on their top line marching equipment that you will on their professional solo and symphonic instruments. These instruments are "best in class".
