I have been hand-crafting and selling clarinet mouthpieces for over 20 years. However, everyday, I seem to learn something new and exciting. Sometime it is a new technique that offers better quality. Sometime, it is a small design change that can make major differences in tone and resonance . After all these years, I am still excited about working with mouthpieces.

  News about the new mouthpieces!  

After months of research and study, I am proud to announce that I am now producing mouthpieces from my own designs. I call them the Grabner HiTech Clarinet Mouthpieces. Since the retirement of Hans Zinner, I am the only mouthpiece craftsman to completely redesign and manufacture not one or two mouthpieces, but an entire line of mouthpieces, including:

  • Eb Clarinet
  • Bb/A Clarinet
  • Alto Clarinet
  • Bassett Horn
  • Bass Clarinet
  • Contra Alto Clarinet
  • Contra Bass Clarinet

Produced using cutting-edge, 21st-century technologies, these mouthpices were designed using CAD software and are realized through very high-end additive manufacturing. The designs are traditional, with subtle improvements that help meet the demands placed on the 21st century clarinetist.

I have been asked several times why I chose additive manufacturing to produce my mouthpieces, and about the material I selected. Click here for a bit more information.

I want to extend a big THANK YOU to the clarinet community. The acceptance of my new mouthpiece models has been very gratifying! Since July, we have made and sold over 400 mouthpieces! They are appearing in ensembles worldwide. Some mouthpieces are already appearing in major symphonies and on Broadway. 

Some models are already clear winners. The B1C bass clarinet mouthpiece has had a amazing reception. For more information, click here.

The S2C, the S3M and the S3M-LE soprano clarinet mouthpieces have also developed a wide following.

Look for more innovation throughout the coming year.

I received an email from a long-time customer about his experiences trying out one of my new mouthpieces. I asked him if I might include his comments on my website. Of course, it is always nice to receive testimonials, but the real reason I included it is that he describes, better than I have ever done, my exact concept of mouthpiece-making.

If you have a question about any of my mouthpieces, please contact me. I am ALWAYS interested and available to answer your questions. I am most easily contacted by e-mail and try to answer all inquires. 

Since 1998, I have hand crafted over 11,000 mouthpieces!      

I have shipped mouthpieces to clarinetists in professional orchestras and bands and at leading music schools around the world, including the following countries:

United States












Costa Rica


Czech Republic







Hong Kong








Republic of Korea






The Netherlands

New Zealand



The Philippines







South Africa











I perform extensively in orchestras, in recital, and as a soloist, and I am proud to say I play exclusively on my own mouthpieces.


I am one of the very few mouthpiece craftsmen who make mouthpieces for all clarinets:


  • Eb Soprano
  • C Clarinet
  • Bb and A Clarinet
  • Alto Clarinet
  • Basset Horn
  • Bass Clarinet
  • Eb Contra Alto Clarinet
  • BBb Contra Bass Clarinet 



A Family of Grabner mouthpieces


Optimized, What does this mean?


Some might call it reed friendly. Since my earliest days as a mouthpiece maker, I have attempted to optimize a given mouthpiece to a certain strength (and brand) of reed. Most of my mouthpieces are optimized for Vandoren V12 reeds and the most popular strengths, either #3, 3.5, 3.75, or 4. Of course, other brands of reeds work fine, such as Gonzales, Vandoren Rue Lepic, Peter Leuthner, etc.

Every soprano clarinet mouthpiece is also tested using Legere Signature European Cut Reeds.

The S3M-LE and the SP1 are specifically designed to use the Legere Signature European Cut Reeds.


The concept is to make mouthpieces that fit reeds that are available, making reed selection easier and adjustment less arduous. Each mouthpiece is tested against several representative reeds fitting the description and style of the mouthpiece. How well I succeed can only be decided by your reactions and playing experiences.  Any feedback you can give me is welcomed.

Trial and Return Policy


Please do not ask me to ship you mouthpieces without a deposit payment. Mouthpiece blanks are not free, and my time is not free. I have a liberal trial and return policy that should easily meet your needs. 


Trial Rules:


You may order by using the shopping cart (PayPal), sending a check, or calling with a credit card number. All mouthpieces must be paid for in full before I can ship them. Refunds on returned mouthpieces are processed promptly.


Your invoice has two dates, the Invoice date (shipping date) and a Due Date. The trial period ends on Due Date (Set to three weeks after Invoice date, four weeks for international orders).  


Returned mouthpieces must be postmarked by the Due Date indicated on the invoice.


Returned mouthpieces postmarked after Due Date are considered purchased and will be returned to purchaser.  E-mail in advance if there is going to be an unavoidable delay.


Mouthpieces returned with non-removable tooth and/or ligature scratches will be considered purchased and returned.


There is a $5 cleaning/sterilization fee per each returned mouthpiece.


There is a $2 fee if the packaging box/label must be replaced.


Please use a box to mail returned mouthpieces. Padded envelopes do NOT work. click here to see an example.


If you are returning a mouthpiece, you are responsible for it until it arrives at my address, printed above. To be safe:

Ship the item using an approved carrier.

Save all tracking info or other proof of shipment.


I recommend USPS Priority Mail. Within the U.S. USPS Priority mail is very safe and reliable, but not infallible. To be completely safe, use Signature confirmation and/or insurance.



Serial Number Tracking


As a service to my mouthpiece customers, I put serial numbers on my mouthpieces. In my records, I keep serial #, facing info, internal and external dimensions, and type and origin of blank.  Therefore, if YOUR mouthpiece is lost or broken, I can duplicate it for you.  This is important protection for your future playing security.




* Pitch:  I offer mouthpieces at 440 and 442. Of course, I cannot guarantee the pitch of your clarinet by mouthpiece alone. There are too many other factors. What it does mean, is that the 440 mouthpieces will generally play at 440 with a standard 66 mm barrel. The 442 mouthpieces will play higher using that same barrel.


The 440 mouthpieces can play at 442 with a shorter barrel, usually 1 mm shorter.
