Used in tenor trombone wraps

Our newly designed tenor offset tube comes into the tenor valve squarely, and seats well in the valve port opening.  Excellent upgrade in this tube!

These tubes are typically used in pairs. 80 tubes replace the 45 and 90 tubes on an axial conversion.  Use 2 for a cleaner look, and a more open softer curve for air flow.

There is nothing like the sound of nickel tubes! Two 80 tubes can replace the 45 and 90 tubes on an axial conversion for a cleaner look, and softer more sweeping curve for better air flow.
