I have been using various Monette pic mouthpieces with my Yamaha Custom piccolo. Has anyone experienced this setup: In order to play in the center of the horn at A440, I have to pull the A-pipe out quite a bit. Actually, the distance from the Monette mouthpiece rim to reciever is just a hair shorter then having a Bach mouthpiece inserted. Diagram below.... Monette AP6LM: MP----pipe---------receiver }-----========] Bach 3E MP---------pipe----receiver }-----------=====] With the shorter Monette pic mouthpiece, I assumed that just like my Monette C mouthpiece, the overall length of the instrument/mouthpiece should be relatively the same, only with the tuning slide drawn in to around 1/8". But, like I said, to play in the horn's center at A440, I have to pull the pipe out to match the length of a conventional mouthpiece/pipe/instrument. Any thoughts? Thanks!
