An ABS resin bell and a fibre-reinforced plastic body make this sousaphone ideal for the rigours of the marching band. \n \nThe 301 Sousaphone features an ABS resin bell and FRP (fibre-reinforced plastic) body for a big, tuba-style sound, while remaining lightweight and balanced for performance ease. It is extremely durable and weather resistant, and the bell front design enhances tonal projection. The intonation is highly accurate and players will appreciate the securely centred notes and easy playability. \n \nHand-lapped valves and slides \n \nHand-lapping is a time-consuming finishing process which results in an airtight valve/piston fit for noiseless, responsive action. \n \nWell-balanced \n \nThe YSH-301 is well-balanced so it is easy to hold while marching. \n \nHeavy bracing throughout \n \nBecause the sousaphone is used in marching band, it has heavy bracing throughout the instrument to make it more durable at the vulnerable points. \n \nPressure formed tubing \n \nPerfectly rounded tubing results in less turbulence and a smoother air flow, thus allowing for an excellent scale and reduced resistance. \n \nFibre-reinforced plastic \n \nThe material in the YSH-301 makes it lightweight to reduce fatigue while marching. The ABS resin bell is durable yet lightweight.
