Bell Treatments

A soldered bell tends to have a very centered sound with a lot of core (fundamental). The articulations are slightly dampened and softer with the solder, while the sound is more direct and compact.
An unsoldered bell has a very wide sound with more overtones. Articulations are easier with an unsoldered rim. More near feel is apparent with these bells as the sound is wider, which helps give the player more feedback.
Tempering occurs when a bell is spun twice on a mandrel which work hardens the bell. This adds brilliance and colour to the sound.
Double Buffed
Double buffing thins the bell slightly. It actually creates a thickness in between any two gauges.
Heat Treated
Heat treating is a baking of the entire bell. This softens the metal immensely and creates a very dark sound. This works best on heavier bells as it tends to free them up. Heat treating is not recommended on thinner bells as it makes them more prone to mute dents. The CF treatment has virtually replaced heat treating.
CF Treated
CF treating is a partial heat treating process. This treatment allows the bell to blow more freely and adds colour to the sound.

“Edwards trombones are the most efficient horns on the market. My horns allow me to play with the level of precision and artistry I need to express myself. I’m also impressed by how Christan is always working to take an already amazing product to the next level.”
