https://www.nhgazette.com/2025/02/01/9rxme4cuy By installing the main pipe trigger system, we achieved accurate pitch control and weighted sounds at the same time. If you press the lever plate during playing, the main pipe is slid down and the pitch decreases. When returning the lever plate, the main pipe and return tube will return to their original position. When tuning, loosen the rod base screw before playing, adjust the pitch by moving the main pipe tube. Then fix the trigger rod by tightening the screw at the position of your choice.

2. Adjustment of lever plate stroke width - By turning the screw with a commercially available minus screwdriver, the stroke width of the lever plate can be adjusted. At this time, the movement width of the lever plate and the movement width of the main pipe are synchronized.
