I have a Tromba C trumpet and the Faxx 3C is a perfect match. Wouldn't hesitate to purchase again.
Faxx Trumpet Mouthpieces
The Faxx mouthpieces were developed as facsimiles of the more common designs at more economical prices. Only the most popular sizes have been reproduced to guarantee the lowest prices possible for these quality trumpet mouthpieces.
These polycarbonate mouthpieces are wonderful for marching season!
Great mouthpiece for the price. Suitable for a variety of uses. Would be a perfect fit for Tromba (Allora) & pTrumpets
