Peter has been very interested of late in the health ramifications of his mpcs, that's why he developed his stainless steel models. Likewise, he developed this delrin line to replace the hard rubber mpcs. He told me about them when they were in development but personally, I haven't tried any. I am still loyal to my HR alto piece regardless of any gas that might be leaking from them. You get my age on my diet and gas from a mpc is a bit redundant. :mrgreen:
For 20 years I have offered a line of mouthpieces called the Custom. In the past they were made of Ebonite (hard rubber). Ebonite (hard rubber) was developed to make bowling balls and has as much as 30% sulfur, which out gasses. This is why the color fades and they begin to have a sulfur odor.
I discontinued the Custom mouthpieces three years ago because of the material. I tested many materials and finally found Delrin, a high tech synthetic material that is FDA approved for food use, so you can imagine how safe it is to play. Delrin has many other qualities which makes it a much better material for mouthpieces than hard rubber.
Delrin actually costs the same as stainless steel. The older Custom mouthpieces were patterned after my brass M2 mouthpieces. The new Custom mouthpieces in Delrin use the same computer program as my stainless steel models. The perfect mouthpiece for players who don't like to play metal but want a modern mouthpiece with a similar response and sound.
