For sale is a preowned C.G. Conn 20K BBb Sousaphone, serial number 224752. Manufactured by the legendary C.G. Conn company, this horn is known worldwide for its traditional sound, rugged durability, and massive projection. It is in good playing condition, has been adult owned, and is ready for the marching field or the stage.

This instrument is ideal for Mariachi, Norteño, and other large marching or performing ensembles that require a deep, thunderous low end and an authoritative visual presence. Its classic Conn sound is perfect for anchoring a rhythm section with power and tradition. It is also an excellent choice for a dedicated student who needs a high-quality, full-sized instrument for school band.
