Product Overview

The Walsh 104E is the Signature mouthpiece of Steven Walsh. We are grateful for the assistance of Steven Walsh in the refinement of the Wedge Gen 2 Euphonium mouthpiece line. After receiving two samples of 104E and 103E Steven suggested some adjustments in the cup shape and throat to enhance their performance. The result was a significant improvement over the original design, which was incorporated into all Series E mouthpieces, and the Walsh 104E signature mouthpiece.

  • The Wedge E Series Euphonium Line - The Wedge E Series Euphonium line was developed at the request of euphonium players who wanted a Wedge mouthpiece made specifically for their instrument. The E Series mouthpieces have a second generation Wedge rim design that incorporates elements from our highly successful Gen 2 high brass rim. They have an accentuated oval shape that extends right down to the base of the cup. This unique oval cup shape amplifies the effect of the Wedge rim, providing greater responsiveness and more core to the sound compared to a conventional cup of similar depth and volume. The cup has a deep bowl shaped contour, similar to other popular euphonium mouthpieces, with the addition of the Wedge rim and oval shape.


  • Acclimatization - Acclimatization 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.
