Tenor Trombone T350-HB

Tenor Trombone T350-HB

The T350-HB tenor trombone is a no-holds-barred, top-of-the line Axial Flow Valve system. We and many of our customers have play-tested this new model in Elkhorn over the past year. We also enlisted the help of Toby Oft of the Boston Symphony to put it through its paces. We feel the results are striking and are confident that this horn is ready for your consumption.

This horn is based on the T350, but with some important differences. In addition to the patented Harmonic Bridge, hard density cross braces improve the the response of horn. The rose neckpipe counters that harder density to achieve a perfectly-balanced tenor trombone.

While developing the T396-A, we tested the patented Harmonic Bridge on our T350. We found that it worked extremely well with the Thayer valve, but unfortunately, production demands prevented us from adding it to more that one model at the time. After working hard to meet our ever-growing demand, the T350-HB is ready to give tenor trombonists the acoustical tuning that was previously only available on the T396-A.

The T350-HB is available with 8" or 8½" bell flares in a variety of wall thicknesses and tempers with either soldered or unsoldered rims. In addition, you may choose from yellow, rose, or red brass with a clear lacquer finish.

Single and dual bore slides in standard weight and lightweight configurations include three brass leadpipes. Custom leadpipe options are also available in silver and brass.

Finally, changing tuning slide material and design can have a profound effect on instruments. Edwards has many tuning slide options available on request.

This system will work with any T350 or T350-E tenor trombone. For those of you whose horns have a bell tab, the tab will either need to be removed or filed down. The bell tab and screw are no longer needed with the Harmonic Bridge.

Standard Features

Bore Size
.547" or .547"/.562" bore
Interchangeable leadpipe system with 3 leadpipes
Bell Weights
  • 21 Gauge - Heaviest (.028" thick)
  • 22 Gauge (.025" thick)
  • 23 Gauge - Lightest (.022" thick)
Bell Materials
  • Yellow Brass (70% Copper / 30% Zinc)
  • Rose Brass (85% Copper / 15% Zinc)
  • Red Brass (90% Copper / 10% Zinc)
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.
  • Axial Flow Valve
  • Pitched in F
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 Alessi Model will sing for you.

The T396-A utilizes the Harmonic Bridge (US Pat No 8,247,675) and Harmonic Pillars (US Pat No 8,247,675). More information on these will be coming in December.

  • 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-STD-AN
    • The T-STD-AN is the standard .547" single bore all nickel slide. This trombone slide has a more rounded end crook similar to Conn slides. Quick in response, the T-STD-AN blows freely in all registers and adds the warm characteristics of the nickel slides. The intensity of the fundamental is accented with upper overtones providing a unique blend of darkenss and brilliance.
  • 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.
  • T-BC-AN
    • The T-BC-AN has the same end crook as the T-BCN but with all nickel outer tubes. This slide combines the width of blow with a centered sound and quick response never before found without these material combinations.
  • T-DBN
    • The T-DBN is a .547"/.562" dual bore slide. This slide has a bass crook and provides the biggest sound in the middle and lower registers, ideal for an orchestral second trombonist.
  • T-DB-AN
    • The T-DB-AN is also a .547"/.562" dual bore, but with all nickel outer tubes. This slide has a bass crook and provides the biggest sound in the middle and lower registers, ideal for an orchestral second trombonist.
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
  • RawBrass
  • Lacquer
  • Silver Plate
  • Gold Plate
  • Satin Finish

In Their Own Words

Steve Wiest

"The Excalibur version of the T302 is simply the best jazz trombone that I've ever played! It has a wonderfully warm tone, but is capable of cutting right across an entire big band when necessary.

"Add to that an overtone series that slots beautifully and you get what I believe to be the best jazz trombone on the market!"
