The Rocky Mountain Hunting Calls Rogue bugle tube is a combination of Rockie Jacobsen’s inventing prowess and Steve Chappell’s uncanny ability to kill big bulls. This Bugle Tube is built with the V.E.T.T. system so it contains a spring tuned to the precise dimensions inside the specially made mouth piece. The spring creates more volume, stabilizes higher notes, makes raspier low growls and allows for easier octave changes. The Rogue is less than 18” in overall length which makes it easier for packing. It is made with a 1 1⁄2” mouth opening and tapered lip adaptor, vibration dampener (Tube Tamer) on inside of the tube and comes fully assembled and ready for use with your favorite mouth diaphragm.
The V.E.T.T. system contains a spring tuned to the precise dimensions that is located in the front section of the call. The spring helps create more volume, stabilizes the higher notes, maintains higher pitches and takes less air pressure to operate while blowing into it.
