** Seele or soul of a mouthpiece, is the cylindrical space in between the throat and the actual backbore. When enlarging the soul, the mouthpiece gets more resistance because of the air that travels slower towards the backbore. When shortening the soul, the resistance gets less and the sound more round.
* All backbores can be goldplated as well. Please contact me, for getting a quote on goldplating the backbore of your choice!
