Instrument Innovations Tenor Rotary Valve plays more open than a traditional rotary valve without the extra wind required by an axial flow. Ball bearing technology allows lightning fast, smooth, and quiet operation. The pressure releases at half stroke with the venting system, which is only possible because of their precision machining. No lapping required. The rotor rides between bearings which eliminates the abrasion that causes the valve to lose seal.
The starting price (with F valve C10, C9 or C8 configuration.) is $5,100
The starting price (straight gooseneck C10, C9 or C8 configuration.) is $3,950

Our optional cut bell with lightweight brass or 3D printed carbon bell rings make our horns the ultimate traveling trombone!
We also offer compact "flat" cases that fit in any airline overhead for both tenor and bass trombones.



Satellite counterweight
Our satellite counterweight is infinitely adjustable for perfectly balancing your horn to your own preferences. Something never before offered (that we are aware of) is the possibility of balancing your bell to slide weight laterally in addition to front to back balance. We honestly had our doubts whether this would make a difference until we tried it!! Moving the weight inward can greatly reduce wrist fatigue. There are two weights included. Choose one or both and move the weight in or out on the rod to adjust front to back balance. Adjust the brace bracket with the included tool to move the weight inward to adjust lateral balance. Our bracket fits most rear braces for Bach, Butler, Edwards, Shires etc… (.420 OD inch brace)
Speedyflo waterkey, New and Improved!!!
We changed the shape of the lever to allow for water to drain much better to avoid the dreaded "pool" of water at the base of the lever. Butler Speedyflo © water key has a very large opening to allow for quick release of moisture. It does not change the flow of air through the tube as there is no "dimple" on the inside of the tube. It uses an O ring to seal the opening and has a curved shaped plunger that matches the inside wall of the tube. In addition it uses a compression spring for much longer spring life.
