Frequently Asked Questions

The Hagmann system utilizes a progressive bore design, reducing friction and allowing for quicker, more precise valve response – crucial for fast passages and nuanced articulation.
While it won't offer the ‘open’ sound of a conical bore, skilled players can still achieve a jazz tone; it’s more about control and precision than inherent ‘spread’.
It allows for experimentation with different bell sizes or materials (if you choose to swap it), subtly altering the instrument’s tonal characteristics and response – a feature favored by advanced players.
