Did You Know?

All of the Precision Machined Warburton Trumpet Top Designs - including the signature models - are available in the following materials:

  • Silver Plated Brass
    • By far, the most popular choice as nearly all players start out with silver and stick with it. Players with an allergy to silver should try our gold-plated or "Warbonite" versions.
  • Gold Plated Brass
    • The gold surface has a slightly more slippery feel than silver. More info...
  • Lexan Clear Plastic
    • The Lexan models are preferred by many players for hot weather use because the Lexan is less prone to slide around on sweaty skin
  • White Delrin Plastic
    • For cold weather use, some players like the temperature-neutral characteristics of the Delrin
  • "Warbonite" Hard Rubber - NEW PRODUCT
    • Feels similar to polished polycarbonate - soft, but with a secure, non-porous "friction grab"
    • Very efficient: Many hard rubber formulas were play-tested. One imported German hard rubber outperformed all others and earned the name Warbonite.  A Warbonite hard rubber top, when combined with a brass backbore has been shown to produce more volume-per-effort than an all brass setup, while sounding more radiant than Lexan or Delrin plastics.

The Warburton system lets you choose a combination of rim diameter, cup style and depth, with a backbore to best balance your sound and resistance. This flexibility means you can have the most efficient mouthpiece with which to perform in any given playing situation.

Our two-piece system consists of fully interchangeable "TOP" sections and "BACKBORE" sections. Due to the many demands placed upon the modern brass player, the variety of Warburton cup designs are able to produce the most desired sound in any playing idiom.

The backbore sizes compliment the cup designs and further assist in the refinement and "fine-tuning" of the sound. Consideration has been given even to the placement of the backbore into the receiver (amount of gap).

Final Cut

The Warburton system allows the player the opportunity to personally "balance" their equipment. This can now be accomplished without the necessity of traveling to a mouthpiece maker or waiting for a mail-order custom made piece that often does not work and cannot be exchanged.

Warburton backbores are available in thirteen standard sizes for Trumpet, Cornet, Schilke Piccolo Trumpet and Blackburn Piccolo Trumpet.

With many years of experience, the Warburton staff can assist you in choosing a mouthpiece well suited to your needs.

In addition to the Warburton component-based system, custom mouthpiece work is our specialty. We can modify any manufacturer's mouthpiece to work with Warburton components. Gold plating is available too.

How to choose the appropriate Warburton Mouthpiece

Note the size of the mouthpiece currently used and consult the Approximate Comparison Charts below to find the Warburton mouthpiece diameter that is the closest to the diameter of the present mouthpiece. This is a good place to start unless there is difficulty with the diameter size of the present mouthpiece (i.e. too large? or too small?). After choosing a comfortable diameter, try one diameter size up and down to confirm the diameter selection.

Select an intermediate size backbore (6 or 7). Note that at this point this backbore is for test purposes and is to be used to settle in on diameter and cup shape. Other backbores will be tested later to balance the sound.

Play various cup models of the chosen diameter according to performance needs and desired sound:

Desired Sound Try these cups
Studio leadESV, ES, S, SV, or M
Piccolo sound S, SV, or M
Brass quintet M, MC, or MD
Orchestral MC, MD, D, or XD


Repeat the same musical passage, such as a scale, and compare the changes in timbre and settle in on which sounds the best. Remember, compare sound, not technique.

Using the cup selected, try a tighter backbore (one with a lower number), then one that is more open (one with a higher number). There will be a noticeable difference in the way it blows as well as in the way it sounds. This will give you a good idea of which direction to move to find a backbore that will suit your needs. While the Star (*) series backbores may feel more free blowing, depending on the player, these backbores may not focus as well as the standard series. This will be a personal choice.

Once a combination has been selected, go back and confirm the cup selection and then play the original mouthpiece as a comparison. You and your listener will hear a difference and you will feel a difference.

Remember that different styles of music may require different equipment to achieve the appropriate sound for the job. So, change equipment to get the optimum sound, not the method of playing.

If you run into a situation during a fitting session that you need assistance with, remember that help is only a phone call away at 1-800-638-1950.

Note: It is a good idea to have a listener familiar with your sound, or one whose judgment you trust, present for the entire fitting session.

Trumpet Top Cup Designs:

ES - "Extra Shallow" - otherwise similar to the S design.


ESV - Similar to the SV design with "V" style cup, but not as deep as the SV.


S - A shallow "bowl" shape. Preferred for lead playing and commercial work. Ideal for D, Eb and Piccolo trumpet.
Warburton ES Cup Design

Warburton ESV Cup Design

Warburton S Cup Design








SV - Medium shallow "V" style cup. This is an exceptional "high-velocity" cup for Piccolo trumpet and all upper register work.

M - Medium depth with a modified "V" style shape. Our M cup design is the most popular because it works well in all playing situations from jazz to symphonic.

MC - Medium "bowl" shape. The MC cups could be the ultimate in bright symphonic sound!
Warburton SV Cup Design

Warburton M Cup Design

Warburton MC Cup Design








MD - Medium deep "bowl" shape cup that produces a rich, dark, symphonic sound.

D - Deep "bowl" shape. This cup shape produces the fullest of symphonic sound. It is ideal for the cornet parts with its warm sound.

XD - This extra deep "V" style cup was designed to give the traditional cornet sound. Herbert L. would be thrilled with this model.
Warburton MD Cup Design

Warburton D Cup Design

Warburton XD Cup Design







In addition to the designs shown above, we also offer the following options:

W - Wide Rim Option - Any of the Trumpet, Cornet, or Flugelhorn tops can be ordered with the W rim option which provides an additional 0.020 inch (twenty-thousandths of an inch) of outside diameter for players accustomed to slightly wider/fatter rims. "W" gives you just enough extra width to be noticeable, but not too much to the point where it feels bulky. Note that the W option is not available with the Signature models.

Anchor Grip - We also offer the "Anchor Grip" Top option - click here to learn more about the Anchor Grip.

Signature Trumpet Tops:

Terry Warburton Signature Top

NEW PRODUCT!

TW - Designed by Terry Warburton specifically for his own lead playing back in the 1970's, the shallower cup design is well suited for players who prefer the Bach 3C cup size but spend much of their playing time above the staff. Has a slightly wider rim with a modified outer edge shape for added comfort and support. Inside Diameter .660”, Outside Diameter 1.095”, #27 bore.

While the factory fire in 2005 destroyed nearly everything Terry owned, there were a few boxes of personal items stored off-site. During the recent move to Mims, FL Terry found the original piece in one of those boxes! It didn't take long to copy the design such that our computerized machines can now accurately reproduce it. 



Arturo Signature Trumpet Top
ARTURO - This is Terry Warburton's CNC (what is CNC?) version of Arturo Sandoval's 40 year old Bach Mt Vernon 3C. Inside Diameter .660”, Outside Diameter 1.086”, Medium deep bowl, #27 bore


Shoop Signature Trumpet Top
SHOOP - (Chad Shoopman) - Inside Diameter .587”, Outside Diameter 1.087”, Shallow V style cup, #28 bore. This is the top demonstrated in Chad's famous YouTube video. Chad prefers our #10 backbore. More info on the SHOOP model...


BWA Signature Trumpet Top
BWA (Brian Anderson) - Inside Diameter .590”, Outside Diameter 1.058", Shallow v-bowl, semi-flat rim, bore #28. This is similar to the Marcinkiewicz Ingram model, but with more room at the top of the cup. More info on the BWA model...


P.RODRIGUEZ Signature Trumpet Top
P. RODRIGUEZ (Pete Rodriguez) - Inside diameter 0.660", outside diameter 1.075", bore size #27. Similar to our 4MC cup, but with a slightly deeper and more bowl shaped cup. More info on the P. RODRIGUEZ model...


JH Signature Trumpet Top
JH (Johnny Hodges) - Very shallow V-bowl high compression lead piece. Johnny prefers our NY backbore with this top. #8 inside diameter (0.620"), Outside Diameter 1.055". More info on the JH model...


JLM Signature Trumpet Top

JLM (Joenuel Lebron Millan) - Shallow V-bowl cup design. Inside diameter 0.656". More outer diameter than standard #4 rim (1.095"). Bore size #27. Joenuel uses our "NY" backbore with his JLM top. This is a shallow lead-style piece great for players who use the Bach 3 diameter and find it difficult to play the smaller diameter pieces. More info on the JLM model...



CK Signature Trumpet Top
CK (Craig Konicek) - Shallow lead style cup with no "undercut", comfortable, #5 inside diameter (0.650"), 1.090" outside diameter. This is an alternative to the Marcinkiewicz Shew #1 model. The rim is wider to the outside and more defined on the inside.


CT Signature Trumpet Top
CT (Chris Tedesco) - Based on Warburton 4SV, but with larger entrance into the throat. 0.660" inside diameter, 1.075" outside diameter, bore size #27.


ODNEAL Signature Trumpet Top
ODNEAL - Very small inside diameter with a shallow V cup design and round rim. Inside diameter 0.590", outside diameter 1.090". Similar to our Shoop model but with a wider entrance.


WCC Signature Trumpet Top
WCC (Bill Carmichael) - A shallow V cup with very small inside diameter of 0.590", outside diameter 1.090", semi-flat rim, bore size #26. This piece does not feel as small as the dimensions would indicate due to the shape and outside diameter of the rim.


AQUINO Signature Trumpet Top

L AQUINO - Shallow V cup design, inside diameter 0.630", outside diameter 1.090", bore size #27. This top is being played by top call Latin lead player Luis Aquino and is a great alternative for players who find the Marcinkiewicz Shew #1 to be too wide on the inside. Luis prefers our #5 backbore with this top for all his lead work. More info...

Also available:

L AQUINO "Pops" Model - inside diameter 0.590", outside diameter 1.090", bore size #27



R.BIRCH Signature Trumpet Top
R.BIRCH - Personal top of Bob Birch. Inside diameter 0.680", outside diameter 1.090", medium-deep bowl, bore size #23. This is similar to our 2MD, but with more girth at the bottom of the cup and a more pronounced inside bite. More info on the Bob Birch model...


KT Signature Trumpet Top
KT (Ken Titmus) - Shallow V "Hammock" style rim slopes inward - no "undercut". 0.640" inside diameter, 1.090" outside diameter. This top should be tried by 13a4A players who have trouble with bottoming out.


MF Signature Trumpet Top
MF - This model was programmed for John Robinson, based on the true-V style of Maynard's original Giardinelli MF1. The nature of the rim contour which "melts" into the cup makes exact inside diameter specs difficult to explain using just one number, but using our method of measuring inside diameters that number would be .590". The outside diameter is 1.050".


Fraze Signature Trumpet Top
FRAZE - This top was designed for Mick Fraser of the Royal Australian Air Force Showband. The rim shape is reminiscent of the old Jet Tone Studio Model B and the extra shallow cup features a dropped undercut. This top would appeal to players who start off great with very shallow cups, but have trouble later on in the performance. Inside diameter .620" Outside diameter 1.090"



RW (Rich Wetzel) - Perfect for any classical or jazz guy who wants more of a lead piece but for whom the more shallow and narrow lead pieces feel too small, this is a great alternative. About the same cup width as a 3C, feels just little bit deeper than the SV or CT cup with 25 hole.  Inside diameter .640" Outside diameter 1.075" Bore #25

Trumpet Backbores:

New Product Alert - H Backbore:
H Backbore - ​The​ ​"H" backbore fits squarely into the commercial category ​as it seems to perform best with a fast moving airstream associated with shallow cups. Featuring ​a longer blank with reverse taper in the venturi, the ​"H" is preferred by strong lead players who are able to convert the high resistance into an efficient and focused buzz. The benefit is that the "H" projects the full spectrum of their sound rather than just making the highs more piercing.​
H Backbore ​Specs:
  • Length overall - 2.85"
  • Bore - 27 at interface, 28 at -215"
  • Comparative resistance - Warburton 4

"I find the H backbore to be more efficient for me than the NY.  For longer, harder gigs, I'm able to back off and my endurance is increased.  The H provides great projection.  The H also works great with my 5MW on picc."
Jon Yates, Air Force Band

"I keep going back to the H because it makes me sound like a more seasoned player."
Brian Anderson, Ringling Bros Circus

Order your H Backbore from our online store
1, 2, 3 - Our tightest commercial sounding backbores. These models have a concentrated and intense sound. The #3 is the most popular of this series. If offers a bright, projecting sound that is great for lead players and outdoor work.

4, 5, 6 - Tight to medium. With progressively less resistance, these models produce a bright and very projecting tone. The #5 is by far our most popular with strong lead players.

Q Backbore - New in 2004, the Q is our most aggressive backbore, preferred by lead players who also need to maintain dominance in the middle register without spreading or over-loosening their chops. More info on the Q backbore...
Qm Backbore - New in 2008, the Qm is a slight modification to the Q backbore. A modified taper in the venturi section slightly compresses the air column to increase velocity before releasing the air into the main body of the backbore. The result - An exciting commercial sound with an intense center.
NY Backbore - This backbore was inspired by the sound of the old Giardinelli #3 (default) backbore made popular by Maynard and others in the '70's. The New York sound was broad, bright, and acoustically loud - which are also the qualities of this backbore. Resistance is just a bit tighter than our #5.

"Just when I told Ken the "Qm" backbore was permanently attached to my 4M top, he said "You may want to try this New York (NY) backbore first." It didn't take me long to realize how efficient this backbore was. There was more center, more core, more volume, and I don't mean loudness, although there was plenty of that, too. In short, it enhanced all the best qualities of the instrument without sacrificing anything. It instilled confidence. As a side note, I noticed in the Blue Wisp Big Band how well I could hear myself in the section, thinking I was overplaying, but not getting tired. It's simply a well balanced backbore for any commercial type work."

Kevin Moore, Cincinnati, Ohio
National Tour-"CATS", Blue Wisp Big Band

Kevin Moore

KT Backbore - Added to the line in mid 1987, this backbore appeals to commercial/lead players and is characterized by its projection and secure slotting of notes above high C. The comparative resistance falls in the 4, 5, 6 series.

7, 8, 9 - Medium large sizes. The #7 has been the best selling model because it provides a good balance of sound quality acceptable in the orchestra as well as the concert band. Models #8 and #9 are very well received by the orchestra player who appreciates the increased volume of sound with less resistance.

10, 11, 12 - Very large "Symphonic" sizes. These models have very little resistance and offer the strong player the potential for the ultimate in full, rich sound.
Schilke Piccolo Trumpet - These "S" backbores were designed to enhance response on the Schilke P5-4 piccolo trumpet. They are identical to our standard cornet backbores, but have a narrower exterior taper. The most popular models are the S10 and S10-star.

The "SERIES 80" Option

Most of our backbores (1 through 12 and the KT) are available with the SERIES 80 option. SERIES 80 backbores have been well received by trumpet players wishing to increase their maximum controllable volume, and by those seeking a denser, more authoritative core to their sound.

SERIES 80 backbores are so named because the large "barrel" section measures 0.80" in diameter.

Read our FAQ page about the SERIES 80 to learn more

Series 80 Backbore

We offer three styles of trumpet backbores:

The STANDARD Series - Our standard series models have long established themselves as the most popular choice for nearly any playing situation.

The STAR Series - These were designed to allow each of the STANDARD models to be more free blowing without the necessity of reaming to a larger bore size. This is important because the quality of sound remains the same without the risk of losing focus sometimes caused by playing of too large bore size. Since these models were made available, the medium large sizes (7* to 10*) have been very well received in the orchestral trumpet community.

The "B" Series - They are exactly like the STANDARD and STAR series internally. The only difference is in the external dimension which is slightly larger and causes a subsequent increase in the GAP. This added diameter can re-establish a functional gap distance in trumpets with worn receivers and where the mouthpiece receiver has been soldered to the lead pipe improperly.

While we recommend the use of our STANDARD series for most situations, if there is a noticeable problem with "LOCKING-IN" of the upper partials, the "B" backbore will very often rectify the problem.

Warburton Cornet Mouthpieces


Cornet Tops:

BC - Extremely deep. British Cornet" style cup. Tradition, classic. Very deep cup, full rich tone. Produces a warm tone with great volume of sound (when required).

MBC - Medium British Cornet to facilitate easier playing in the upper register without losing the full sound.

XD - Extra Deep. Large "V" shaped cup for players that may want some assistance in the upper register without sacrificing tone.

D - Deep. Extra-large bowl shaped cup for players wanting to produce a great volume of tone.

MD - Medium "bowl" shape. The MC cups could be the ultimate in bright symphonic sound!

MC - Medium. Medium "bowl" shape, producing a bright symphonic sound. Also used by players who bottom on shallow cups.

Wide Rim Option (W) - Any of the Trumpet, Cornet, or Flugelhorn tops can be ordered with the W rim option which provides an additional 0.020 inch (twenty-thousandths of an inch) of outside diameter for players accustomed to slightly wider/fatter rims. Note that the W option is not available with the Signature models.

Cornet Backbores:

1, 2, 3 - Our tightest commercial sounding backbores. These models have a concentrated and intense sound.

4, 5, 6 - Tight to medium. With progressively less resistance, these models produce a bright and very projecting tone.

KT Backbore - This backbore falls between the 5 and 6 in resistance and produces a compact sound appropriate for outdoor and Dixieland playing.

7, 8, 9 - Medium large sizes. The #7 has been our best selling model for the past nine years. This series produces a quality of sound acceptable in the orchestra as well as the concert band. Models #8 and #9 are very well received by the brass band player who appreciates the increased volume of sound with less resistance.

10, 11, 12 - Very large "Symphonic" sizes. These models have very little resistance and offer the strong player the potential for the ultimate in full, rich sound.

There are three styles of cornet backbores:

The STANDARD Series - Our standard series models have long established themselves as the most popular choice for nearly any playing situation.

The STAR Series - These were designed to allow each of the STANDARD models to be more free-blowing without the necessity of reaming to a larger bore size. This may help to avoid losing focus sometimes caused by playing too large of a backbore. Since these models were made available, the medium large sizes (7* to 10*) have been very well received by orchestral cornet players.

The BC Series - These British cornet backbores are shorter than the standard cornet backbores. They were specifically designed for use with the BC tops, resulting in an overall length of 2.25". These are very popular with brass band enthusiasts.

"I experienced an instant improvement with the new set-up. What I thought was a mediocre model 927 Besson was transformed into a great horn. I don't even have to trigger the A above the staff, and the high C is perfect. The sound is exactly what I was looking for!"

Warburton Flugelhorn Mouthpieces


We offer Three Standard Models:

  • FLM - Medium funnel shape with a #20 bore size. This model has a lighter sound and is preferred by players who need to play in the upper register.
  • FL - Standard deep funnel shape with #16 bore size. This has been by far our most popular model over the years.
  • FLX - Extra deep funnel shape with a #14 bore size. This model is capable of producing a most beautiful classic Flugelhorn sound for orchestral and other large ensemble work.
  • Plus our Wide Rim Option (W) - Any of the Trumpet, Cornet, or Flugelhorn tops can be ordered with the W rim option which provides an additional 0.020 inch (twenty-thousandths of an inch) of outside diameter for players accustomed to slightly wider/fatter rims. Note that the W option is not available with the Signature models.


The inside rim diameters and rim shapes are identical to the trumpet models 1 through 8.

The following shanks are available:

  • standard American taper
  • "French" taper, which fits the Couesnon and French Besson Flugels
  • "Bach" - (Longer shank to fit Bach Flugelhorns, Kanstul 1525, & Leblanc Sandoval) - special request only
  • "Vintage One" - (Wider shank dimension to compliment Conn Vintage One Flugelhorns) - special request only
Warburton Flugelhorn mouthpieces are 1-piece models because each cup-depth has a corresponding bore size to match.

Access to a Warburton Master Kit enables one to test in logical fashion for the correct combination of diameter, cup style and backbore configuration that will result in a proper balancing of the equipment. This process can be extremely beneficial under the direction of a qualified Warburton Dealer or Representative. A smaller more compact "Studio Mini kit is also available. This kit is currently being used as a valuable diagnostic tool by university trumpet instructors nationwide.


Our aim is to have one or more of our kits available to the trumpet community in all geographic areas. Please take advantage of this system by calling the factory for the Dealer or Representative nearest you.
