King KMT411S

With excellent balance, weight, and ease of carriage, the KMT411 is a four-valve marching tuba with the added flexibility to control typically difficult intonation issues in the low register. Designed with input from the low brass staff at the Blue Devils, the KMT411 provides a solid bass voice in the brass choir. The .734” bore and 19” bell make the KMT411 ready for the demands of marching activity.
