EDWARDS T-350CR-E TROMBON TENOR

Bore Size

.547" or .547"/.562" bore

Leadpipe

Interchangeable leadpipe system with 3 leadpipes

Slides

T-STDN

The T-STDN is the standard .547" single bore slide. This slide has a more rounded end crook similar to Conn slides. Quick in response, the T-STDN blows freely in all registers. A very centered tone can be achieved with this slide.

T-BCN

The T-BCN has a bass end crook similar to Bach slides. The squared-off design of this crook allows for a very open low register and a bigger sound overall than the T-STDN slides. This slide is also a .547" bore.

Tuning Slides

Single Radius

Single Radius tuning slides are the most common. They have one continuous bend from small to large end. They are very free blowing and open in all registers.

Dual Radius

Dual Radius tuning slides have two bends. The shape is more square with the two bends making a flattened top. The dual radius provides a quicker response and ease in the upper register, however, the sound is more compact than the single radius tuning slide. All dual radius tuning slides are CF treated to offset the compact nature of this tuning slide.

Both types available in yellow or red brass

Valve

• Enhanced Rotor Valve
• Pitched in F

Uni-Harmonic Pillar Brace

Similar in concept to the harmonic bridge found on the T396-A and the T350-HB, this brace allows for a single harmonic pillar to be added to the horn in order to fine tune its sound and feel.

Bell Treatments

Soldered

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.

Unsoldered

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.

Tempered

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.
