Interchangeable leadpipe system with 3 leadpipes

Slides

B-STDN

The B-STDN is the standard .562" bore bass trombone slide. This slide provides a player with greater flexibility in the upper register. It is most comparable to the Bach 50 slide. The B-STDN has a yellow brass outer slide with nickel sleeves and endcrook.

B-STD-AN

The B-STD-AN is the standard .562" bore all nickel bass trombone slide. The B-STD-AN has an all nickel outer slide without nickel sleeves. The all nickel slides are drawn to the same wall thicknesses as our yellow outer tube slides. This ensures forte volumes stay well in control by the player while giving a faster response and more core to the sound.

B-DBN

The B-DBN is a .562"/.578" dual bore slide. This slide adds width to the sound and blows freely in the low register. The B-DBN has a yellow brass outer slide with nickel sleeves and endcrook Three leadpipes aid the player in achieving the desired compression of the individual instrument.

B-DB-AN

The B-DB-AN is a .562"/.578" all nickel dual bore slide. This slide adds width to the sound and blows freely in the low register. Three leadpipes aid the player in achieving the desired compression of the individual instrument. The all nickel slides are drawn to the same wall thicknesses as our yellow outer tube slides. This ensures forte volumes stay well in control by the player while giving a faster response and more core to the sound.

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.

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.
