  • Specifications
    • Inner Diameter: .660 measured .04 inches into the cup.
    • Outer Diameter: 1.114
    • Cup Depth: This mouthpiece has an M (Medium) cup, which is similar to a Bach 7E, Schilke or Yamaha B, Curry M, and Warburton M cup. It is an excellent all round mouthpiece with a very versatile sound. It is suitable for concert band, marching band, and jazz or big band. The M cup can also be made to blend in a chamber group or orchestral setting, especially when used with a heavyweight backbore in order to darken the sound. It functions well as a Piccolo trumpet mouthpiece with a medium cup is desired. Players using a Bach 3C should select the V cup modification option, which makes the M cup more similar to the Bach 3C and darkens the sound slightly.
    • Backbore: This mouthpiece comes on a Medium backbore.


  • Wedge Generation 2 Line - The Generation 2 trumpet mouthpieces are designed to incorporate the advantages of the Wedge rim and oval cup in a mouthpiece that is very comfortable and easy to adapt to from a conventional rim. The rim is slightly wider than our original Standard Brand rims. This mouthpiece has our new Double Oval Cup (DOC). The diameter of the rim and cup in the vertical dimension is 10/1000 of an inch larger than it is from side to side. This means that the oval shape of the Wedge rim is continued down to the base of the cup where it joins the throat. The DOC design, found only in Wedge mouthpieces, provides the added efficiency of a smaller mouthpiece with the big sound, clear attacks, and flexibility of the larger mouthpiece.


  • Acclimatisation - Acclimatisation time varies, but most players find they have fully adjusted to the new rim shape within a few days. Most players are able to alternate between a Wedge rim and conventional rim, although the vast majority of players will convert all of their mouthpieces to the Wedge design because of its obvious advantages once they have adapted. We do offer discounts to players who need to purchase a number of Wedge mouthpieces for various instruments.

    Chuck Findley 66M.Trumpet mouthpiece

    Posted by Loyce M. on 2019 Mar 20th

    I purchased the plastic and the one trumpet mouthpiece. I received the plastic vetrsion and tried it. I have been playing Bach 1C wedge version and love it. The plastic 66M seemed to be working so I ordered the one piece. I found out quickly it was not working and sent them both back. Customer service worked with me closely on this and received full credit because I had taken good care of them. I am still sticking with the Bach 1 C Wedge version. The 66m is a great mouthpiece it just did not work for me. In recommend Wedge for the product and their service.
