Butler Carbon Fiber Bass Trombone

Model C12

This amazing instrument has all the sound qualities you would expect from a high end bass trombone but only weighs 4 lbs. Almost all of the weight is centered over the shoulder to allow for stress free playing.

• Carbon fiber bell, tuning slide, outer hand slide, F slide and Gb slide. Total weight of the instrument is 4lbs.
• Double independent rotary valves with bearings for very smooth operation.  From Instrument Innovations
• .562 bore
• 9.5 inch bell
• CF/nylon 3d printed hand grip for comfort.
• Multiple leadpipe options.  Our multi threaded design takes both coarse and fine threads. (Shires or Edwards).  2 Long and short carbon fiber leadpipes matched to this horn included.
• Ultra lightweight hand slide.  The outer CF slide weighs only 80 grams.
• 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.

Instrument Innovations Bass Rotary Valves play more open than traditional rotary valves 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.
