B454-HB Bass Trombone

Bass Trombone with Independent Axial Flow Valves and Harmonic Bridge

B454-HB Bass Trombone

The B454-E has received a major facelift with the addition of the patented Harmonic Bracing and material updates. Borrowing from the B502 models, this bass trombone uses yellow brass tubing within the valve wrap and the B454’s yellow brass turn points to keep the center and response right where we want it. The Harmonic bracing utilizes harder density cross braces as well as the lower bell cross brace. The Axial Flow Valves still have an open feel, but the ease in the upper register comes in now, and the clarity of articulation is much improved.

As we move towards a more organic response, working with bass trombone players we’ve recognized that we need to make an instrument natural to the player rather than forcing them to change their ways. If you’re tired of face manipulation and trying to “work” at getting the sound you are after, then this is the instrument you need.

Give us a call to discuss bell choices that will enable you to get the sound that’s in your head out to the world.

The B454-HB comes standard with Bb/F/Gb(D) tuning. Other tunings are available upon request.

Specs & Features

Bore Size

.562" or .562"/.578" bore

Leadpipe

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-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.

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.
Materials
Both types available in yellow or red brass

Valves

  • Independent Axial Flow Valves
  • First Valve Pitched in F
  • Second Valve Pitched in G, flat G, or Gb

Harmonic Bridge (US Pat No 8,247,675)

Consumers (and even some manufacturers) often overlook the importance of bracing. It's vitally important for two reasons. First, a solid brace design allows manufacturers to build stress-free instruments. Second, an instrument's playability and response will be exponentially better with braces in the correct nodal positions on the instrument. This means the B454-HB will sing for you.

The B454-HB utilizes the Harmonic Bridge (US Pat No 8,247,675) and Harmonic Pillars (US Pat No 8,247,675).

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.
