The BRAND NEW 10MFAN Virtuoso soprano sax mouthpiece…

October 21, 2020 By Mark Sepinuck

The biggest game changer to hit the soprano marketplace!!!

After months and months of working on this original design soprano mouthpiece, I am incredibly pleased to announce that it is done, and it’s an absolute game changer in the soprano mouthpiece marketplace. This is the most flexible and versatile soprano piece out there. It can be warm and full, and it can be punchy with brightness depending on the players ability. It doesn’t force you into either direction and I would say WITHOUT ANY HESITATION that this is the finest all-around, do it all, soprano mouthpiece available to players!

$335 introductory price. German bar stock hard rubber, hand finished by the best in the business.

Tip openings:

5*—055, 6—.060, 6*—-.065, 7—-.070, 7*—-.075

Brian Powell is doing great hand finishing on my mouthpiece models.

FIBERREED synthetic reeds—-oh yeah!!!

March 6, 2020 By Mark Sepinuck

Well, Ive tried so many synthetics over the last 3 decades, and this was a very welcomed moment for me.
I had been using the Fibracells on tenor for the last couple years, but the quality control seems to have disappeared with those, as the sizings are all WAY OFF now. I ordered 6 of the Fibracells a few months ago, and they went right into the trashcan.

Now onto better news! I talked to my friend Danni at Fiberreed, and had him send me a package so I could see what they were up to these days, since its been so long since I tried those. Ive played on all of the different cuts and materials now, and wanted to check in here and share the great news.

Well, all the reeds played and did what they were designed to do. …ALL OF THEM. I prefer one of the cuts the most for what I want, but all the others were very good.

This was a joyous day for me!!!!!! Finally, a reed brand I can really love again, since my old Hahn reeds stopped being made.
Never thought the day would come, but its here. After the Hahns, I went to Legere and Fibercell, but the love affair faded with those, and the Forestone weren’t for me either.

I ended up on the Fiberreed Carbon for tenor, which is their black and white reed, and they are amazing for what I want. 
A beautiful pairing with my Robusto!!! Clean, clear, full, with great response, character, and depth. 
Excellent subtones and great altissimo too.

Happy as can be!!!!!!!

2020 HUGE news from 10MFAN Mouthpieces!

February 7, 2020 By Mark Sepinuck

10MFAN MOUTHPIECES: Innovation over imitation!

YOU asked for it, so here it comes.


10MFAN Mouthpieces is a collaborative effort, and I am grateful to have such great people working with me. Our engineer at the shop is tremendous at what he does, the guys at the shop do fantastic work, and my craftsman, BRIAN POWELL who does all the handwork, is the BEST OF THE BEST! We are working ridiculously hard here, so let me update you as to whats going on.
I’ve been asked for quite some time to make some mouthpieces with a rollover baffle, rather than just the step baffles that I have been using.
I’ve been working on the 1st rollover alto and tenor pieces for quite some time, to make available more unique ORIGINAL designs into the marketplace.

10MFAN NEW Chameleon tenor powerhouse mouthpiece
1st HR TENOR ROLLOVER MOUTHPIECE—–COMING EARLY APRIL!!! I wasn’t sure how I was going to like this, but tons of prototyping is always the answer to get what you want. The first rollover baffle tenor mouthpiece is done! It is a powerful and beautiful player with lots of volume and freedom in the blow, without having a step baffle there. I have had loads of guys tell me they want to try my mouthpieces, but they like roll-over type pieces and not step baffle pieces. I have worked extremely hard in making this happen and we are finally there. The shop is finishing up the last request that I had, and they will be getting the first group of these out to my craftsman in the next couple weeks. They will be ready for orders in April. This one I am releasing first, is the powerful model. Its got a huge, full open sound with tons of volume available, while retaining clarity, depth, richness, and focus. Definitely a “cross-over” category piece thats great for so many playing situations. It can be played subtle for a jazz setting, and balls to the wall when you need it. For all you players who want power and volume and feel its got to be a high baffle step mouthpiece or nothing—-YOU’RE WRONG!

I got a great compliment on this one from the first person to play it other than my craftsman and myself. He said it reminded him of a great Freddie Gregory Mark lll tenor piece he used to own……but better, with far more flexibility and versatility and a much bigger sound.

We are staring out with sizes 7, 7*, 7**, 8*, and 9.


1st HR ALTO ROLLOVER MOUTHPIECE—-AVAILABLE IN EARLY MAY. The 1st alto mouthpiece is almost done and it will appeal to all you Meyer lovers I want that beautiful even sound top to bottom but would like a larger chamber so that the sound is more full-bodied and has more spread than a medium chamber.. This was my objective with this piece. I have decided to go with a warmer and fuller approach for this model and make an original design alto piece that has a rollover baffle and scooped sidewalls, and a chamber like my Classic tenor model. It’s really a great combination and this mouthpiece will be available in May.
There are so many Meyer copies out there and everybody likes to raise the floors up and/or add more material at the baffle to give their copy pieces more punch. My thought process is to make something original that the Meyer and Link players will really enjoy. A deeper chamber that will still allow for plenty of volume and a really beautiful depth to the sound. My Daddy O and Showboat altos have step baffles and more punch and power than the Meyers, so this new alto will be my category one mouthpiece, and will really knock it out of the park. For the guys who play warm and like that warmth, this mouthpiece will make them incredibly happy, and a warm power and punch will still be there for them.


The 10MFAN 2020 TIME LINE CALENDAR FOR THE REMAINDER OF THE YEAR: Most of you know me for selling my mouthpiece line, but probably never think about how much work actually goes into designing and prototyping when you are making completely ORIGINAL mouthpieces. As we speak, I am working on everything listed below. I absolutely love what I do!


SPRING: 1. My website is being redone to make room for all the new things going on here, and will be done mid-March. 2. My new CHAMELEON tenor model in hard rubber is now available to pre-order in 7, 7*, 7**, 8* , and 9 tips.

SUMMER: My 1st warm and full sounding rollover baffle alto mouthpiece that all you Meyer and Link guys will go crazy for, will be completed.

FALL: My first HR SOPRANO rollover mouthpiece will be released. Tired of seeing all of these Selmer Soloist copy pieces out there and nothing new going on? I sure am. I will bring something new, original, unique, and exciting to the marketplace for soprano players.

WINTER: A very special tribute hr tenor mouthpiece will be released—–cant wait to show you this one!!!!!!!!



More to come….. Stay tuned!!!

Ron Coelho from RPC Mouthpieces has passed away.

January 4, 2020 By Mark Sepinuck


My heartfelt condolences go out to Rons family. Ron and I go back a couple of decades. I am so saddened by this news and I wanted to put up a post, and just say thank you for all the great memories. Ron was a wonderful person and always fun to talk to. You could call him up and ask him one question and you may be on the phone for an hour. He loved to talk, and he would share everything with you. He was very real all the time. Conversations would jump from one topic to another and he was very knowledgeable about many things. Ron used to get Babbitt blanks and he would build them up on the inside to get what he wanted. He would make different baffles and add height to the floor with many different combinations, to get the players what they asked for. Over the years of selling mouthpieces as a major part of my living, I was lucky to have owned over 100 of Ron’s pieces. Like any mouthpiece out there, they are not for everybody, but Ron would do his absolute best to get you what you asked for. He was extremely passionate and compassionate. He had his ideas of how to do things and he followed his passion. I greatly appreciate that as I do the same in my life.

Ron started using this orange material called Ultem, and after I heard from many of my friends how much they enjoyed that material in terms of playability and looks, I wanted to try it myself to see what I thought. Needless to say, I have tried many different plastics, carbon fiber, wood, 3-D print, etc., and the orange Ultem is superb. I started offering it in my 10Mfan mouthpiece line as soon as I got the first mouthpiece back, because I knew it was wonderful. Again, I want to thank Ron for trying this material and proving it to be a wonderful material for mouthpieces, and allowing guys like myself to not have to go through the difficult trial and error of inding a great material, because this Ultem is fantastic and I am very grateful.

I’d like to take this moment to thank Ron for all the great conversations that we had, and for the wonderful mouthpieces he made for players all over the world.

Ron, you will be missed!

Orange Ultem hand finished 10MFAN mouthpieces offered all year round now. Info here.

December 7, 2019 By Mark Sepinuck

Due to the huge success I have had with these ORANGE ULTEM pieces for the last six months, I am now making these Ultem mouthpieces available all year round in all of my alto and tenor models, in all of the tip openings. They can now be ordered directly from my website.
I want to thank my friend Ron Coehlo for trying out this material first. He really found a great resonant and super stable material for mouthpieces, and I encourage all of you to check out his RPC mouthpiece line. Ron makes beautiful pieces! I’m happy to be offering this material because it really is outstanding.
These hand finished, semi transparent orange mouthpieces are only $365 each for alto, and the tenors are only $385 each just like their hard rubber counterpart that I offers.

***A DISCLAIMER FOR THE ULTEM MATERIAL***
Some of the Ultem pieces will show some machine marks on the inside of the Ultem pieces because they are semi transparent. Its NOTHING to worry about. Any marks are from a tool path change and it does not affect anything. It’s part of the process when making the orange pieces because of the material. (We cannot hide that because it’s see through). It just depends on how difficult the particular model design is to cut with the tooling paths. Some models like the Classic and Robusto rarely ever show a mark because they are more open designs internally. If you see tool path marks, don’t fret, just play and have fun with the mouthpiece. My Chameleon mouthpiece always shows a little divot mark just under the table. Again, it affects absolutely nothing.
I play test EVERY PIECE myself, so I know for a fact that NO mark you see will affect the playability of any the mouthpieces. That is for sure. I am all about the playability and sound of my pieces.
