As we develop more models they will be listed on the chart below.

It is a time intensive process to get the rim reproduction and cup integration correct.

     The cup is a convex design for a more efficient sound and better intonation. The Jet Tone rim reproduction was paramount to get to the original Ratzenberger/Amado era design. The Bolton J backbore is an exact dimensional replication.

     The advantage to the Bolton Mouthpiece is that you can use any Warburton thread backbore with the desired top with the rim of your choosing.

Bolton Brass is happy to announce 4 new back bores in the line up.

- Model J - This is the classic Jet Tone sound that is well centered.

- Model K - This model is brighter and more projecting than the Model J. This is the one Jet Tone should have had in the 
arsenal. It has a beautiful bright sound that is not harsh or overbearing.

- Model L - Brighter than the model K. You might peel paint with this one. 

- Model V - This model is very broad and symphonic sounding. It has many of the sound qualities as the Bach #24

-Model E - This is our tightest back bore. If you like tight and bright, this is the back bore for you.
