HT3CS-28 GOLD PLATE Commercial Trumpet Mouthpiece

I play on is the new HornTrader custom signature mouthpiece by Mark Curry. The HT 3CS-28. I am selling these pieces for $150 ( SH&I) Basically it is a high compression shallow 3C Trumpet Mouthpiece It is a slightly shallower Mt Vernon 3C copy with his #1 Back-bore and a 28 hole. My HT 3CS 28 is a rim that was copied from a Mt Vernon 3C that belonged to Arturo Sandoval Then the Cup was made a tad shallower (.017) but also a bit more room on the sides near the bottom of the cup The bite is soft like a worn Mt V 3C The contour is more straight to the shallower cup The drill is a 28 The Back bore has a 28 hole but is a straight taper #1 reamer. Medium tight with brilliance. About .017 shallower than a Mt Vernon 3C cup We’ve opened up the 2nd cup which should make it a little more free-blowing. And have added a slightly sharper shoulder going into the throat, making it a little more angular instead of a smooth radius. The X-28 Backbore has a 28 hole but is a straight taper #1 reamer. Medium tight with brilliance. Length 3.5′ Weight 3.2 oz. Backbore exit diameter .333′ Outside shank diameter .383′ (gives a gap similar to a Reeves #5 sleeve) Can cut new ones for sleeves (add $25) Extra Sleeves are $25 ID .666′ at 30 thou from the top of mouthpiece Bite radius .069′ OD 1.07′ Undercut angle 15.5 degrees main cup shortened by 17 thou, 2nd cup slightly wider, more angular. 70 thou/inch reamer, tight 28 throat.

MC Series

With a unique double cup design, the MC Series combines a moderately shallow first cup near the rim for comfort and response, with a second cup towards the throat that produces a rich tone not commonly found in mouthpieces of this depth.

C Series

This model mirrors a traditional C cup, featuring a strong core with remarkable versatility. It responds well across a wide range of dynamics and styles, making it suitable for various performances from commercial to orchestral.

*30C, 40C and 65C in development*

Monette Prana Mouthpieces Used

info@horntrader.com — Sun, 04 Jan 2026 21:27:08 +0000

USED Monette B6 Prana (Bb Trumpet) $300

USED Monette C6 81 15 (C Trumpet) $300

Prana mouthpieces became widely available in 2002 and ushered in a new era for Monette mouthpieces and instruments. Compared to a mouthpiece with the Classic internal configuration, a Prana will allow for a more resonant sound, more effortless playing through the full range of the instrument, and greater ease of dynamic control. Prana mouthpieces work best for players who use an open, neutral physical approach

What do all the markings on my Monette mouthpiece mean?

PREFIX

Mouthpiece names begin with a prefix that indicates the instrument for which the mouthpiece was designed:

B = Bb trumpet (or cornet)
C = C trumpet
D = D trumpet
E = Eb trumpet
AP = A piccolo trumpet
BP = Bb piccolo trumpet
FLG = flugelhorn
FL = Flumpet
TS = Trombone (small shank)
TT = Tenor Trombone (large shank)
BT = Bass trombone

RIM SIZE

After the prefix, the first number indicates the rim size. Smaller numbers indicate larger rim sizes, and larger numbers are smaller rim sizes. The B1 trumpet mouthpieces have the largest rims, with B2 mouthpieces being slightly smaller. BL mouthpieces are small ‘lead’ rim sizes.

The letter W indicates a wider-diameter version of a rim. The B2 S3 W is a wider-diameter version of the B2 S3, and the BLW S1 is a wider-diameter version of the BL S1.

CUP DEPTH

Subsequent letters and numbers generally indicate cup depth:

L = lead (shallow cup)
LV = lead, very shallow
LS = lead, shallower
LD = lead, deeper
M = medium deep
D = deep
FL = ‘Flumpet’ cup, deep and V-shaped

CUP VARIATION NUMBERS

Additional markings such as S1, S2, S3, etc., are cup contour design variations. These numbers generally do not indicate anything specific about the size or depth of the cup. Different sizes with the same ‘S number’ are generally not related.

OTHER MARKINGS

Prana = Prana internal configuration

P = Prana internal configuration

81, 82, 84, 88, or similar number= backbore numbers

10, 12, 15, 17, 19, 20, 22, 23, or similar number = throat size

359, 375, FT = flugelhorn mouthpiece shanks

350, 355, or similar number = custom, nonstandard specs

2-3 letters likely indicate the initials of a player for whom a custom mouthpiece was designed or made

Used Kanstul Mouthpieces

info@horntrader.com — Mon, 17 Nov 2025 22:43:51 +0000

Kanstul offers more models and options for trumpet mouthpieces today than any other mouthpiece manufacturer in the world. As an innovator, Kanstul pioneered the next generation of mouthpiece production back in 2000, with our revolutionary Renishaw scanner. For the first time, exact copies became available on any line of mouthpiece. Using a modular concept, players were now enabled to use different manufactures cups or backbores to offer an endless variety of choices.

This also led to another Kanstul innovation: the Mouthpiece Comparator. An extremely useful tool for the discerning artist, enabling them to visually see and overlap one cup or backbore with another, thus allowing the player to analyze the subtle difference in rim contour, cup shape and backbore taper. One of the first artists to avail themselves of the new technology was Wallace Roney, with his Gustat mouthpieces that Miles Davis had left him. So exact and beautiful was the copy of this mouthpiece that when the Sony corporation decided to have a special edition release of all of Miles’s recordings in a special trumpet case, they included a Kanstul replica Gustat mouthpiece with each one.

We now invite you, the player, to come into our site and see what a difference your mouthpiece can make in your quest for constant improvement of your sound and technique…especially if it is a Kanstul Precision Mouthpiece

Used Bob Reeves

HISTORY

Bob Reeves Brass Mouthpieces was founded in 1968 in Hollywood, California. A U.S. Navy-trained machinist and toolmaker, Bob Reeves apprenticed in the craft with custom mouthpiece maker Carroll Purviance and making trumpets at the Benge Company in Burbank, CA, before opening up his own shop.

Our earliest mouthpieces were custom made for professionals working in the studios and concert halls around Southern California, but quickly expanded as word spread about the solutions Bob Reeves Brass had to offer. Players would drop by the shop when the popular road bands would come through Los Angeles. Eventually, the custom mouthpieces we made developed into the line of mouthpieces we make today.

MANUFACTURING

Every Bob Reeves Brass mouthpiece is made in our factory in Valencia, California. From the carefully sourced raw brass that arrives in the shop to the finished, silver or gold plated mouthpiece that leaves the shop, every step of the process is done under our roof. This guarantees that our mouthpieces meet the highest quality standards around.

DESIGN

Each Bob Reeves Brass mouthpiece model is designed with both the musician and audience in mind. The rims contours we offer provide a range of diameters and contours that give the musician many options to maximize comfort and performance. Our cups and backbores have been developed to play in tune, respond quickly, and produce a rich, colorful sound with minimal effort on the part of the player.

HOW TO CHOOSE A MOUTHPIECE

The most important aspect of any mouthpiece selection is choosing the right rim. Once you have a rim you love, we recommend putting it on everything. That is why most of our mouthpieces come standard as 2-piece screw rim models.

Once you have a rim you love, the rest of the mouthpiece should fit the demands of playing you do and help you achieve the sound you want. Then, you can fine tune your mouthpiece to your instrument by adjusting the gap with the Reeves Sleeve System.

If you would like help in choosing a mouthpiece we are happy to help. We consult with players of all kinds and at all levels on a daily basis.
