The vortex, also called a double throat, is a narrow 'V' shaped section directly below the main cup.
It combines the flexibility and tonal depth of a deeper mouthpiece, while maintaining a strong center and quick response. Given the more open feeling compared to our standard backbore, it may require a bit more support in softer dynamics.
Again, much care was taken to ensure excellent playing qualties: an even feel and resistance across the entire range of the horn with outstanding intonation.
This backbore is offered in bore sizes ranging from 4.4mm to 5.8mm in 0.2mm increments in American external taper and from 4.4mm to 5.2mm in German external taper.
