Steady Blowing is one of the hardest things to learn on the Bagpipes. This manometer has been specially designed for easy use with the bagpipe. There are 2 different attachments that adapt to your pipes. One piece fits between the bottom of the blowpipe, and fits between the blowpipe and the blowpipe stock. This is the piece that holds the manometer gauge. The other piece fits between the bottom of the outside tenor stock, and outside tenor bottom. This piece allows the air pressure in the bag to be measured. The gauge is easy to read as it is in your site of view.
