Re: Marcinkiewicz E12.4 (Ingram) trumpet mouthpiece. I love this mouthpiece for the high energy, commercial performing I do, but am struggling a little when it comes to softer, more gentle playing, using this piece. (Small-group Jazz for instance) For those who use the Ingram, what mouthpiece do you use for the 'other' stuff? Bear in mind, there is NOWHERE in Australia to try any mouthpieces, hence the need to ask. Thank you!
