NEW PRODUCT: Warburton Traditional Trombone Tops

(Click here to see the One-Piece Models or Signature Models)
The WARBURTON system facilitates the brass player's choosing of a mouthpiece with the optimum combination of rim diameter, cup style and depth, and backbore. This unique ability allows a player to fit together a mouthpiece that will best balance sound and resistance with his own instrument. The choices available with the WARBURTON system will afford one the most efficient mouthpiece with which to perform in any given playing situation.

"Warbonite" Hard Rubber

The system consists of interchangeable "TOP" sections and "BACKBORE" sections. The various cup designs have been chosen for their ability to produce any sound desired by the player. The different cup depths within one diameter allow the player to easily change mouthpieces to perform in a different context. The backbore designs complement the cup shapes and further assist in the "fine-tuning" of the sound.
The WARBURTON system allows the player the opportunity to personally "balance" their equipment, a process that heretofore was not within grasp!

Warburton TOPS


A shallow "bowl" shape.
The WARBURTON S cups are the shallowest pieces on the market.
For unusual upper register demands or the ALTO trombone, these models perform well.


These are medium depth with a modified "V" contour.
The M cup is preferred by players doing LEAD work in big bands.


These deep cups produce a very full sound and are our most popular models.


The "SYMPHONY-TENOR" models are exactly that.
The large cup volume produces the ultimate in sound to fill the largest auditorium.
These cups should be used with the ST model backbores.


All of the B cups are very deep models that are intended for use with the BASS trombone.
Combined with the B series of backbores, these models will excel in the low register.


Bore .250".
The T series is the standard for Tenor trombone.
They are numbered from 1 to 6, with 1 being the smallest and 6 the largest.


Bore .250".
The T* (STAR) series is the same as the T series except that there is no cylindrical section.
The T* models are somewhat more free blowing than the standard models.


Bore .266".
There are 3 models for the ST backbores.
They are numbered from 1 to 3, with 1 being the smallest.
It is worth noting that these models were designed for the large tenor; it is not just a tenor backbore with a large shank.


Bore .281".
The three B backbores fully complement the Bass cups in providing a full sound that is rich in harmonic overtones.
Number 1 is the smallest and 3 the largest.
NOTE - ST and B backbores are also available to fit Old Conn 88 and 72 models and Boosey & Hawkes euphoniums.

"From the moment I played the first note on the Warburton 6T mouthpiece I knew that this was something special for me. I don't change equipment much. I've played the same horn (King Silver Sonic 3B) for more than 30 years and in that same time I've used about 4 different mouthpieces. I wasn't looking for a mouthpiece, but I thought I would give it a try. Boy am I glad I did. I knew it was something special right away. I've been playing it ever since.

The Warburton 6T mouthpiece feels very secure in all registers and in all volumes, in all situations. I love it."

My new Warburton 12M-T4 is the perfect mouthpiece for me for playing long phrases on ballads. As leader of the Jimmy Dorsey Orchestra I have to play some of the solos that Tommy Dorsey used to play when they were the Dorsey Brothers Orchestra. The comfortable rim, the quick response and ease of articulation makes every register just sing out. I have searched for a long time to find this perfect mouthpiece.

Warburton One-piece Trombone, Euphonium, and Baritone Mouthpieces

We are pleased to announce that due to so many people wanting a high quality one-piece trombone mouthpiece in sizes that they are familiar with, we have designed a complete line of one- piece trombone mouthpieces. While the numbering system is familiar, (using Bach nomenclature), each model has been designed to eliminate problems that have come to light over the years. We have made the rims more comfortable, and the throat sizes are balanced to the cups. The backbores are maximized for tone production and projection.

I cannot begin to describe how much I like the 4GD, it is the perfect fit for my Yamaha 842S Euphonium. I would recommend this mouthpiece for anyone wanting to produce a big, rich, and full sound on a large horn. I have received numerous praises from teachers and colleagues regarding my sound, intonation, and note accuracy since making the change to the 4GD.

Introduced to the Warburton 5G "L" (.290" bore) at the Euphonium/Tuba conference at Ft. Myer, VA in Jan 2003, Air Force Master Sgt. William Jones has been playing it ever since.

A prominent Washington DC performer and educator, Jones has been featured as a soloist and clinician throughout the country. His former teachers include retired Air Force Chief Master Sgt. Dr. Brian Bowman, Murray Crewe, Roger Hanson and Barry Morrison.

Sgt. Jones is a Willson artist, so he chose the "E" (Euro) shank.

Signature Trombone and Euphonium Mouthpiece Models

In addition to the full range of Warburton One-Piece and Two-Piece models, we also offer the following Signature models:

Frank Rosolino Signature Model
Frank Rosolino Trombone Mouthpiece

Model #1:

Inside diameter - small - compares to a Bach 15.
Cup - Shallow "V" style
Bore - .250" (E)
Very free-blowing for a small mouthpiece.

Model #2 inside diameter similar to Bach 12

Model #3 inside diameter similar to Bach 11

The Rosolino piece has proven very popular but there were a few players who could not function with the small diameter of the original, so we made several with larger inside diameters and the guys loved them. These larger diameter models are the Rosolino #2 (12C diameter ) and the Rosolino #3 (11C diameter)

History of the Rosolino Model:

About 3 months before Frank's untimely death in 1978, he and Terry Warburton had worked all day in Terry's shop in Toronto, Canada - working on a mouthpiece design that would outperform the one Frank had played on for 22 years. While it was not easy to do, they were successful. Frank is pointing to that first Warburton Rosolino mouthpiece (our Rosolino #1 model) in this photo:

Terry Warburton and Frank Rosolino, 1978 in Toronto, Canada

Frank gave the original mouthpiece to Terry as a souvenir, and it stayed on Terry's desk until it was nearly lost in the Warburton factory fire in 2005. After the fire, while trying to recover anything possible from the ashes, Terry found the piece buried under where his desk had been. Here's a photo of Frank's original mouthpiece:

Domingo Pagliuca Signature Model

Domingo Pagliuca  and Terry Warburton

Domingo Pagliuca Signature Mouthpiece

Domingo had been playing our RS5 model which was working very well for symphony use. He wanted a brighter version of it that could also be used in the Salsa bands but still be suitable for symphony venues. Domingo visited the factory and worked with Terry through several changes to the RS5 model - mainly adding a slight V shape to the bottom - to achieve the result Domingo was looking for.
