Najoom® Custom Mouthpiece

The two-piece mouthpiece system for trumpet and cornet conceived and designed by Dennis Najoom.

 

Already known for his NajoomÒ Trumpet Leadpipe and French BessonÒ Classic series trumpets, Dennis Najoom wanted to design a mouthpiece system that would closely address the needs of the professional trumpet player who needs to be versatile enough to play in any style.

These superior quality trumpet and  cornet mouthpieces are of the highest precision, fully made using state-of-the-art CNC lathes. Then, each one is hand inspected under a magnifying glass before being approved for sale (really).

This is a simple system where a player can keep the same rim and have five different cups with very different playing characteristics, then use the backbore most suitable to the playing situation.  Simply order the mouthpiece top and the backbore to suit your needs.

Najoom 2-piece Trumpet Mouthpiece

From the TPIN..."I play on the Najoom mouthpieces and I like them a great deal.   They play very evenly and in tune throughout the range.  In fact, I have gotten so used to how easy they are to play, that I am having a great deal of trouble playing on other things.  I really can't say enough about the mouthpieces.  I have been trying several other mouthpieces against the Najoom ones in an effort to be sure I am on the right one, and so far I have not found anything that I like better." --W.D. Chicago

Description & Labeling System

"I want a '1C/MS' top with a '24BB' backbore..."

 

Tops

 

Based on the early 1970's style 1C rim shape/diameter, there are five rim widths and five cup depths available in any combination.

 

1st Number is the size/width of the rim

Choose from one of five rim widths*.

1 17mm
2 16.85mm
3 16.75mm
5 16.50mm
7 16.25mm

*Note: rim measurements are approximate.

2nd Letter is the shape of the rim

All rim diameters are based on the 1970’s style 1C rim, a great combination of superb playability and comfort.

C 70’s style standard 1C rim

 

3rd and 4th Letters describe the cup depth

Choose from one of five cup depths.

MD The deepest cup with a large beautifully smooth sound. C The newest cup.   Between the MD and M, it produces a full sound with good ring. M A little smaller and shaped differently than the MD. It is well centered and full sounding, ideal for most situations. MS Great for commercial and pops and is well suited for Eb and D playing. S, or Insta-LeadÔ A new generation of lead mouthpiece for those who can play a shallow cup. Although shallow, the sides below the rim drop in order to give the lips room to vibrate. You’ll know why it’s called the Insta-Lead.

Frequently Asked Questions

What would you recommend I try in your mouthpiece line?

Start with a  rim diameter similar to what you are presently playing.  Then try the series in that size.

Is your 3 rim diameter similar to a Bach 3C diameter?

Our 3 is very close to a 1½ rim diameter.  1½ and 3C players have no problem playing them.   

How would you compare the rim shape of your M cup and C cup to similar Bach cup?

The M cup is close to a 1½ C cup.  This may be the ideal mouthpiece for all around playing.  Our 3C/M is very slightly shallower than a 1½C with a rim that is a little flatter with a bit more bite.  The 3C/MD has a deeper slightly more V shaped cup and has a beautiful smooth sound.  The C cup is good for big brilliant orchestral work.  I use the MS for most normal pops playing and reserve the S for high penetrating big band style work.  The S cup with a 117 backbore is good for pic.

I'm looking for an all around mouthpiece to use for Bb and C trumpet playing.  What would you recommend for me your mouthpiece line?

The all around mouthpiece might be the 3C/M with a 10 backbore for the Bb and a 24 backbore for the C trumpet.

I play solo cornet in a brass band, so I'm looking for a cornet mouthpiece.  What would you recommend for me to consider for my cornet playing?

For cornet I suggest the MD cup with a 117 backbore.

Is the rim of your "Vintage" cornet mouthpiece different than your other rims?

Our Vintage cornet mouthpiece is designed for the British Style cornet player.   It is very deep with a larger cup, a flatter rim, and has a very large backbore.

Chicago

Via eMail "...I am quite satisfied with my Najoom mouthpiece (1CMD with 117 backbore), which replaces a Bach 1.  It works well in all registers and dynamics, and is extremely comfortable.   The only downside is that I have even fewer excuses for shoddy playing...!"  -- C.W.

Via eMail "...the mouthpiece I am using the most for "legit" playing is 1C/C with 24 backbore.  ...my sound has really focused up.  It also has a nice dark core." --R.C.

 Via eMail "I am writing to know if you send things internationally. The trumpet players here have been trying my stuff and have fallen in love with your mouthpieces.  One trumpet player in particular wants to buy a 1C/C (the one that I am using) ... and a 24 backbore. He also wants to have a 1CS top to go with his backbore for more popular and screaming things that he does." --B.B. Uruguay        (Yes, we   send things internationally.)
