Ken Okutsu Focus Core Alto Saxophone Mouthpiece Review

July 31, 2015 by Steve 3 Comments

Today, I am reviewing my second hard rubber alto saxophone mouthpiece from Ken Okutsu in Japan. It is the Focus Core model and has a 6 tip opening which is .075. (In the sound clip below I mistakenly say it is a Focus Tone but that was a mistake on my part…….sorry Ted Klum…….)   I already reviewed four Ken Okutsu tenor mouthpieces which were all excellent so I have been very curious to review these alto mouthpieces also.

Four New Ken Okutsu Alto Saxophone Mouthpieces

Here is the description and features from the Okutsu website:

Features

  • Long rollover baffle, and almost straight inner side walls and extra small chamber.
  • Bright and clear, contemporary sound.
  • The extra small chamber makes very focused tone.
  • All mouthpieces are crafted by CNC machinery for incredible accuracy and finished by hand carefully.
  • Concave table. It makes the tone full and rich. The practical life span of reeds is lengthened.
  • Material is the highest quality ebonite (hard rubber).

Ken Okutsu Focus Core Alto Saxophone Mouthpiece

The Okutsu mouthpieces are hard rubber and come in a protective plastic case.  Within the case they are wrapped in a black velvet bag.  I received four alto saxophone mouthpieces from Mr. Okutsu.  The alto mouthpieces are the Traditional model, the Traditional II model, the Focus Core model and the High Baffle model.  I kind of like how simplistic and straight forward the model names are.   The Traditional model looks to be the darkest of the four, then the Traditional II looks to have a slightly higher rollover baffle.  The Focus Core has an even higher baffle and the chamber is much smaller. Finally, the High Baffle model has the highest baffle as the name implies although the chamber is bigger than than the Focus Core model.

The mouthpieces look good to my eye.  The hard rubber is shiny and without any imperfections. The gold engraving is neat and clean.  The rails, tip rail, table and baffle look very well crafted and even. (Although you can see a scratch on the table in the picture below, I do not think the mouthpiece was shipped this way…….my wife decided to clean up my office one day when I was gone and put a bunch of my mouthpiece in a desk drawer.  This was one of the casualties I believe…….)

Ken Okutsu Focus Core Alto Saxophone Mouthpiece

The Focus Core model looks to have a very small chamber on it.   The baffle is much higher than the Traditional II  and Traditional models.  The baffle is long and is still pretty high even when it gets to the chamber opening.  This makes the floor of the chamber much higher than on the Traditional and Traditional II which  I believe is what gives this mouthpiece that “focused core” sound that the name describes. As I look at the mouthpiece from the bore side the chamber opening looks even smaller than a Selmer Soloist which has one of the smaller chamber openings out there.

 

Ken Okutsu Focus Core Alto Saxophone Mouthpiece

I thought the Ken Okutsu Focus Core alto sax mouthpiece played great with a Rigotti Gold 3 Light reed. I found that it had a little more resistance than the Traditional and Traditional II but I believe that is from the smaller chamber opening. I think the smaller chamber opening squeezes the air stream down into a tight core and gives this mouthpiece more volume, brightness and core sound because of it. Due to the smaller chamber opening there is an added resistance as your air fights to get through the chamber I think.  I don’t think this is a bad thing though since this mouthpiece takes plenty of air and gets super loud.  It just feels like you are blowing against something a little more substantial than the Traditional model or Traditional II model.

Ken Okutsu Focus Core Alto Saxophone Mouthpiece

The Ken Okutsu Focus Core Alto Saxophone Mouthpiece was great to play.  This is a great mouthpiece for players who want a brighter focused tone that can cut through the mix.  There is loads of power in this mouthpiece.  I kept the sound clip a bit tame because I didn’t want to peak the  recording levels but this piece can really be powerful and knock down some walls if played full force! This is a great mouthpiece for those who want to go in that Sanborn direction but still be able to ease out of that sound when needed.

If you like the sound of the clip below and the mouthpiece catches your interest then please contact Ken Okutsu and give it a try. You can contact Mr. Okutsu at his website at Okutsumouthpieces.com. Tell him Steve sent you………….Great work Mr. Okutsu!!

Let me know what you think in the comments below. Thanks, Steve

    Hey Steve, I like the Claude Lakey sound but it’s not without its issues. I am wondering if this is an option to get a similar sound and feel?

      Sure, it gets you in that territory of really bright alto sax tone. It’s a bit too bright for my tastes but if you want to go that bright then this is a great mouthpiece for it.

I want to thank you again, because, not only are you an inspiration to listen to, you are a fine teacher!

I have been teaching sax and other winds for over 20 years, and you give me that “push” to give my students more!

I just joined Neff Music last month. I can’t tell you how excited I’ve been to be able to pick back up on lessons. I’ve been in a rut and you got me out! I’ve especially appreciated the Lesson Path section. It was so clear I knew exactly where to jump in and start. Many many thanks!
Karin
Thank you for the wealth of helpful lessons you’ve provided over the years.  I truly feel as though it has improved my playing more than the 4 years I spent at Berklee… and that’s not a slight on the school as I loved my experience there.

Your major diatonic patterns book is great. I”m studying the first twenty patterns (first twenty pages) each day with different articulation each day and slowly increasing the tempo each week or so.  There is a noticeable improvement in finger coordination across all keys and its amazing how much more secure I feel on the difficult keys when attempting to play pieces with 5+ flats/sharps. I’m able to sort out the fingerings for these pieces now much more quickly than before, often in one or two … Read more

Mr. Neff,  I want to thank you for sharing your God-given talents through your on-line lessons.  My husband, Michael, is blind, but he is a great sax player and he has been enjoying your lessons for quite some time now.  It’s not unusual for me to hear “Hey, babe, listen to THIS!” – and he will cut loose on his sax, just thrilled at what he learned during his session with you.  His excitement warms my heart!  You have no idea how much you have poured into my husband.  You have opened musical … Read more

Just a brief note to compliment you on your teaching skills and in particular for the honesty of your lessons.  I am a returning alto sax player in my 50’s and I was looking for a no nonsense, straight to the point kind of guidance. I had intended to email you with a few questions regarding the use of the bis key but then I noticed that there was a lesson on that specific topic and after viewing it,  all my questions were answered. I once took a group lesson with a well known professional sax … Read more

Your material is great! I got your New Altissimo Lesson 6 months ago and I have learned more from that than in all my 44 years of playing! I appreciate your down to earth teaching method and I really appreciate the heart that you teach with. I have been a subscriber to your lessons for the past 6 months and I have learned a great deal. Over that period of time I have had some questions and you have never failed to respond. Thanks! I have already recommended your lessons to a number of players in… Read more

I must say again how much I appreciate all your material. Including the video tutorials. It help keep me focused and knowing what to aim for. And your laid back teaching style appeals to me too. 

Thanks

I want to let you know that your instructional material is transforming my playing.  It is an immense pleasure to learn and play now, and I can’t tell you how grateful I am. The instructional material I got from you is by far the best of any I own (and I have over 100 books, DVDs, and what not). I literally can’t thank you enough! Deric

I am enjoying your style of teaching, and you’ve done a great job with the videos….good sound quality and well constructed lessons.  Balances the more guitaristic material found on the majority of guitar based programs.  Jazz vocab is what I’m all about at this point in the journey.   I especially dig the fact that you’ve studied with Bergonzi…helps me see his voluminous output in a more  bite sized way.

I’ve been having ‘ online’  lessons with Steve for a few months now. Being a teacher myself I had had some reservations with the idea at first and the practicalities of it .  Let me just say that my playing has taken a huge leaps forward while studying with Steve and continues to do so.Steve studied with some renowned player/teachers such as Bergonzi and Garzone– this in itself is invaluable but Steve teaches from his own books, which cover a a vast amount of  jazz language.

Never really had lessons before just kinda worked things out on my own. Was in a rut but your lessons are really helpful in opening melodic possibilities. Ur an awesome resource to the saxophone community. Thanks for sharing.

Hey Steve, My name is Jason Freese and I play keyboards and sax in the band Green Day.  I grew up taking sax lessons from Eric Marienthal when I was a kid and got out of it for a long time. I ran into you on youtube while searching for sax stuff. I bought a whole bunch of your lessons and have been loving it! Thanks! Here is my wikipedia so you can see the albums I’ve played on….Thanks again. It’s sparked my interest in practicing again.   Jason

I just started looking at my lessons and I have to say, dude you are awesome.  I ABSOLUTELY will learn from you!  I started the tenor about 1 ½ yrs ago and have since picked up an alto, and more recently a soprano.  I spend most of the time on the tenor, followed by soprano, and have only gotten to the alto a few times.  I think I’ll be sticking with tenor.  I’m having a great time and hope one day to play well enough to get regular gigs.  I’ve been playing keys for about 35 years (… Read more

I have been a member of Neffmusic for more than a year now and have enjoyed every minute of it! I have not only been going thru the Dominant Bebop Scale lessons and book (OUTSTANDING!) but the mouthpiece reviews, solo clips and transcriptions are very interesting. Steve approach to beginning and intermediate improv have given me many new pathways to teach my high school jazz ensemble students. Congratulations Steve, great product!

Hello Steve,

I just want to say thank you so much for your unbelievable work, it is just mind opening, thanks for sharing it.

Thank You Steve. I think that I will be busy for years. Thank You for your great contribution to jazz music. Your books, more than teaching “how to play jazz”, actually teach “how to speak jazz”. I wish I found your methods years ago.

Hey Steve! I hope you and your family are well.  I’m just writing to say thank you so much for all the resources you have made available to the saxophone community. I have been using your material for many years and I always come back to it… in fact I just took a break from practicing to write this…( reviewing “CreatingModern II-V-I Lines with simple pentatonics”.) I am, and continue to be, one of your raving fans! Blessings to you and your family this holiday season! Wishing… Read more

I’m an experienced player in the pop/soul/funk areas of music and, previously, classical.  Over the decades I’ve been playing, I’ve always felt that I could do what I needed in those styles of music.  However, recently I began to feel limited by my use of the same old licks. When I discovered Steve Neff’s website, and heard the audio examples based on the exercises in his books, I realized they were what I needed.  I purchased all of them and have been working on them since.  It’s very hard work… Read more

I feel very lucky to have come across Neffmusic and that feeling will remain with you as you search through a treasure trove of learning materials on offer, you will quickly find the lessons that you are suited to. You will instantly recognize the unparalleled quality of Steve’s teaching … Read more

Steve,  Just want to say thanks for all you are doing for all of us. I’ve learned more from you than anyone else in my 40 years of playing.

If you can give some tips on One Note Samba, Ceora, and Wave… that would be cool.  I really like learning how you apply your concepts to actual songs!

Have a great year,

Kevin Ledbetter

I've learned more from you than anyone else in my 40 years of playing.

Hello Steve, I’m getting so much out of your lessons and books, amazing how much one may think one knows, there is always a new frontier or new way to view something you think you had somewhat down. You have taken it all to a new level and am so grateful. Your lessons are so down to earth and understandable and clear!  Thanks so much Steve! Cheers, Eddie

For anyone living in remote areas away from live jazz sax teachers, Neff is the way to go. In fact this is a great resource for anyone seriously interested in mastering the sax. I’ve never been disappointed in a lesson.
