When you need a case for Tubas, MTS Products is your best choice. These cases are manufactured to withstand the rigors of "Student Abuse". The 1709V is made specifically to fit the Thor Tuba. The outside shell is the same as our 1209V, Large Tuba Case, just as durable and strong. The inside is designed to fit the Thor Tuba with precision. The 1709V is a Special Order Case only, THIS IS NOT A STOCKED ITEM.
