In a 3D printed world, it’s great to see old world craftsmanship alive and well! Something so cool about hand made equipment, so much character and it’s uniquely YOURS. Love the vid, Jay!
I've had the fortune to play these necks and they didn't disappoint. Incredible sound and feel difference right off the bat. Truly incredible craftsmanship.
With all respect, I simply don’t think that you can hear any difference. May be someone can explain to me what a good neck is, and then I mean in technical terms.
@@hansmathiasthjomoe4817 fair enough, I’ve thought the same thing about most fancy ligatures and I realized the difference is often most importantly how the saxophone feels to play. It’s been a few years so you’ll have to forgive me for not remembering specifics but my abiding memory involves resonance and openness. Because the necks were different diameters/materials, they felt much more open to play. It also affects the ease of playing of both ends of the sax range. Easier altissimo/overtones or low register. Also, in person the difference was much easier to notice IMO, it was subtle and probably doesn’t come across super well on RUclips.
WOW! I am Blown Away by the rich tone differences those custom necks achieve, RESPECT! I'm a Biophysicist following my family Luthier /instrument building in retirement, I I also Volunteer at our local school to teach the Science of Music Innovation. We have mixing boards and oscilloscopes to quantify the tonal differences of all sorts of instruments, ranging from Irish Uillean bagpipes (played with helium), to a 17th century Maggini Violin, and of course guitar physics from the Doyle Les Paul innovation. I played the Baritone and Alto Saxophone in High school, and have restored my 1950's "The Martin" Alto. I will certainly include these videos to recruit students and teach the joy of creating music with hammers metal leather and wood..wind..(Smile).
I liked the M61 brass you tested best, it was warmer and more expressive to my ear. And on the Yanagisawa I liked the original neck better for much the same reason, the newer neck sounded more pinched and nasal to me.
I started out as a sax player but became a bassoonist. We spend years searching for the perfect bocal (the neck on the bassoon) to match our instrument and the right bocal makes a world of difference. I'm not surprised that sax players are now exploring this relatively easy way to realize the potential of their instruments. Sounds great!
Very interesting. I always heard that after the player, the mouthpiece & the reed, the neck makes a big difference in the sound, but never had a demonstration of this theory. When you tested the different necks the difference was audible (even via the youtube medium)! On the Yani - the KB neck sounds much more alive!
KB neck sounds better for me. When you speak and emphasize points your voice overdrives and becomes uneven and loud. Vocal consistancy through ranges makes a great sound to all of us animals. Thanks for the video. I stopped playing years ago but I think that I will purchase a kb neck.
Wow, I wouldn’t have known that a neck would make so much difference. To me the KB neck sounded so much more ‘rounded’ and less buzzy than the Yani neck. Huge kudos to Kim’s work and well done for a great video Jay.
I have been to Kims shop here in NYC where I live, AWESOME man and a FANTASTIC place, and what’s even better I was there on a Day when Ravi Coltrane was there trying some different necks, he was kind enough to let me get a pic with him. Love going to Kim’s shop.
Got one of these for my old SMK6(50 yrs) and it completely changed the responsiveness and feel of the instrument. Enabled me to keep the instrument for a few more years.
i really enjoyed hearing both the KB Sax neck and the original neck on your Yanagisawa for different reasons and i think the former really expands the range of color on the sax. awesome video and i look forward to seeing more:)
More core, power, articulation and clarity of the overtone spectrum on these necks than anything else out there. Kim has spent years testing and learning and we are now all benefiting from his research.
The M61 Vanguard was the one for me. Seemed to have a more balanced mix of high and low harmonics at the front of the note with a nice amount of weight behind. Then again, it's as much about how it feels on the player's end of the mouthpiece as much as the sound in front of the bell.
Kim is so great! I've been playing on the HH copper Redwood model for a while and absolutely love it. Thanks for exposing such a great product and human being. 😁🙌🏼
I love the sound of both of them .... I’d use a Redwood for a big band situation where you’re competing with the brass and it’s all about the big open sound of the sax .... the Vanguards I’d use for solo performances and have a couple for different styles ... the second Vanguard you played was a stunning neck ! The very focused sound was just brilliant !! The next one was dark and very “jazzy” for a highly responsive sound .... the last one was such a wonderful sound but very focused and really easy blowing .... I’ve not played them but would love to own just one of them .... one day perhaps ....
Great video Jay. People just dont know half of the process which would have included; annealing, cooling, brazzing (soldering),annealing again to take the stresses out of the piece and allowing the hand tapping, the heat monitoring and the precision manufacturing of all the parts, and this is all before the assembly and testing. Engineering meets the arts. As for sound, I would be as well buying one to hang on my wall to admire whilst listening to Jay.
I bought a B-991 from Kim a couple years ago. He was wonderful to deal with and the horn arrived in amazing condition - perfect adjustment and smooth action.
It felt like the necks really improved your playing. It felt more free and even more sexy. Not only did they just sound better off the bat, but after you had played them for a bit you really opened up more than on the stock necks. Amazing.
Good review. I like how you describe your reaction rather than asking us to "hear" the difference. To me, the important part is how the player has to adjust or not adjust that is important. Most people can force about any sound to a degree, it's the ease of getting the sound by the player that matters. You summed it up right at the end.
I feel that.....before all of these new necks.....Coltrane,Getz,Gordon, Brecker,Hawkins,Webster,Young, Cárter, Parker,Desmond,Sims,Konitz, Hodges,Henderson.....all of them... sounded.....marvelous...!!! I believe that all of these variations on the same...including these new necks.....,is a way to pursue the eternal sax business
Your Yani sounds richer to me with the KB neck. Your Mk VI with the original neck has that true Selmer sound, but the Vanguard M61 in brass takes it up a notch.
Jay and KB . . . from what I can tell, two true masters of their craft who are willing to spread their knowledge and joy about the sax and music to the world. You guys are great thanks for sharing as always!
That tune always reminds me of an old boots Randolph recording my dad loved. You are right about sounding like your self on different gear. If you feel the improvement, that is enough. And yes the KIm B is CRAZY good on tenor.
Kim Bock has dedicated his career to making awesome saxophone necks that improve the sound of the original necks. He can also adjust your original neck to make it sound better. I have many saxophones that he restored for me, and they all play amazingly well.
As a brass TW01 owner I really appreciated hearing the subtle but notable differences with your bronze TW02. No doubt, the KB necks are a vast improvement and add some nice responsive, open and varied character between the redwood and the vanguard. What I find interesting is the tone of your KB necked TWO2 is closer to my brass TWO1! I wish you could compare the brass and bronze Yany models side by side.
Hi the yani with KB is really so much better, it opens the sound up in all directions, and it adds so much more colour to it. That sizzle is there, the depth, projection.... amazing
Great video! Thanks for show us the work from this good master. All combinations sounds really good, hard to decide without feeling the differences by blowing.
This is a fantastic episode! Thanks for the attention to detail you put into it. I’ve been considering one of these for a few years and this video certainly has answered many of my questions and given a amazingly clear closer look at them. Well done. Great work!
Wow, your Yanagisawa is so much more with this new neck... It has been 2 years since I acquired a KB Sax Redwood wrought copper neck for what was a very, very rough vintage tenor I was getting restored at the time. Kim's neck helped transform a dodgy intonation horn into an astonishingly great professional player! Not only were intonation tendencies corrected but the tone and altissimo just opened up making the horn a real joy to play. I'd like to point out that the remote purchase process was a breeze. After a quick discussion about the horn and my setup, Kim recommended two necks, 3 days later I had the tenon measurement tools in hand and by week 3 the mail delivered the 2 pre-fitted necks for evaluation.
The neck is very important. Haven't played a KB neck, but will consider one for my alto. I can say that a Phil Barone neck absolutely transformed both the intonation and the power of my tenor Mk VI (57,xxx,ca.1957). The horn had always been sharp down low, and flat up high, but not so with the new neck. It's beyond anything I would expect, and consistent with various mouthpieces. My excellent tech (and great player) Tim Kochen, in Houston, recommended looking for another neck because my original seemed "dead" to him. So happy he did.
Jay, I cannot say that I really heard a difference when you play these two necks on the Yanigasawa, but you mention that it's fun, so it is definitely worth it. I would like to add that you sound amazing playing both. When you played the various necks on the Selmer, I could tell the difference. Either way, it's always fun hearing you playing and I hope you'll make more videos of you just playing. Your playing is pleasure to the ear.
I felt the difference was much more distinct on the Selmer VI than the Yanigasawa, a better stock neck perhaps. Intriguing the difference produced by a seemingly simpler part of the instrument compared to mouthpieces or the many variables in body shape and materials. A fascinating review, thanks.
Thanks Jay. The sound on the KB with your Yani was free... I love it. I play a SA80ii Tenor and everything else is Yani in my study. I want a Tenor, but I've played the Selmer for 28 years, so it's hard to change. But I want to try one of these necks.
Great Video, great work! This Video just shows the amazing mastermind development of a very important part of the sax, yet a very "underrated" part. The Vanguard necks absolutely work for you, Jay. I do think, that every sax player has to evaluate the progress he or she would make by upgrading - especially in this price range - but the difference is there. It is custom, it is cool, it is KB. Amazing work over there in NYC! Thanks for the Introduction to this stunning brand. Video quality reached a very high level, looking forward to be one out of 200k subscribers ;) Greetings from germany
Hello , c'est vraiment excellent et oui on entend une différence; c'est flagrant ! je préfère le kb sax et concernant le selmer MVI , le son que je préfère c'est avec le premier bocal kb sax que tu as essayé ! Merci pour ces videos d'artisans et de constructeur; c'est vraiment enrichissant 😉
I purchased the tenor neck and waited 4 years for the alto neck....both AMAZING...intonation is greatly improved....the alto neck has a little more resistance than my previous neck, BUT.......that doesn't mean it's a negative.....AMAZING necks....

10/10 would agree that the Vanguard Hand Hammered Bronze sounds nicer than the WO2 Bronze Yanagisawa. Beautiful work!
To you...the player.
Have you tried the comparison with an audience that can't see which neck you're playing?
I liked the M61 brass you tested best, it was warmer and more expressive to my ear. And on the Yanagisawa I liked the original neck better for much the same reason, the newer neck sounded more pinched and nasal to me.

Wow. KB neck really adds a lot more power and character
Just like the boston sax shop reeds, now the poor guy is gonna have orders piling in for weeks! Love the video!
KB neck surprisingly sounds so much better than the Yanigasawa neck! It's got some sort of spiciness, some sort of sizzle that adds depth to the sound
Just like any hobby the attachments are neverending!
At first I was expecting this to be some kind of factory. Fascinating! Craftsmen are few and far between.
Very interesting. I always heard that after the player, the mouthpiece & the reed, the neck makes a big difference in the sound, but never had a demonstration of this theory. When you tested the different necks the difference was audible (even via the youtube medium)! On the Yani - the KB neck sounds much more alive!
glad it was easy for so many to hear the differences.
This sounded like one of those traveling segments on discovery channel. LOVE IT!!!

i am thrilled. the KB neck truly sounds rounder and more interesting than the Yanagisawa orginal neck
That 3rd Vanguard the brightness of it is incredible, thats the sound i choose for my Yanagisawa Tenors and Alto saxophones
The Bronze hammered neck makes the tone come alive. More rich sound, wonderful improvement
Redwood sounds amazing
Got one of these for my old SMK6(50 yrs) and it completely changed the responsiveness and feel of the instrument. Enabled me to keep the instrument for a few more years.
i have one... amazing... and Mr KB customer service is stellar
i really enjoyed hearing both the KB Sax neck and the original neck on your Yanagisawa for different reasons and i think the former really expands the range of color on the sax. awesome video and i look forward to seeing more:)
Thank you for this wonderful visit in the factory, what a treat! Wish it was longer. Blown-away by the No-Testing philosophy!!! 🙏
I’m impressed how much of a difference it made.

I own 2 of them and prefer them to my sba necks.

Wow! What amazing craftsmanship. Superb video, Jay. I personally liked the sound of the M61 brass; so powerful and rounded.
The sound comes from the internal dimensions of the neck (99%) and the material (1%).
I bought a B-991 from Kim a couple years ago. He was wonderful to deal with and the horn arrived in amazing condition - perfect adjustment and smooth action.
The KB Hammered Bronze neck sounded really great on every note. Keep the KB!
Wow that sounds much better. Amazing difference. Glad you shared the process with us.
KB is my favorite
It felt like the necks really improved your playing. It felt more free and even more sexy. Not only did they just sound better off the bat, but after you had played them for a bit you really opened up more than on the stock necks. Amazing.
Great video Jay, fantastic to see Kim working metal in this way. The different tone they all made to your stock MKv1 neck is astounding.

Your Yani sounds richer to me with the KB neck. Your Mk VI with the original neck has that true Selmer sound, but the Vanguard M61 in brass takes it up a notch.
yeah I almost ordered the M61 neck but didn't want a dark neck on my already dark WO2 horn
What a true craftsman and genius. I really dig this kind of content man. Thank you

Jay - FWIW . . . the M61 Brass was the best by far to my ears.
A KB Neck has been on my MVI upgrade wish list for some time. Now after hearing your demo I'm even more anxious to get one. Thanks Jay.
I definitely prefer the sweet sound coming out of the KB SAX neck
Oh yeah-big difference on the Yanigisawa. I am tempted. I have the same horn. Thanks Jay!
haha, I'm sure you'd dig this one. I'll let you try it next time I'm around.

Vanguard Bronze without a doubt, beautiful sound.
The Selmer with the first Vanguard (after the Redwood) and the last Vanguard sounded the best to me. I agree the last Vanguard sounded darker.
That vanguard m61 brass was a beast! So interesting to hear the differences between these thanks Jay

The neck can make a massive difference in the feel and sound of a horn. Both sound good. KB seems to have more fluidity, an edge and a higher ceiling.
Your original Yani neck sounded kind of lonely yet the KB neck sounded more joyful and sunny.
I prefer the sound of the KB Sax neck to the original neck. You seem to enjoy playing more as well.
Perfectly dark in the lower register and equally bright in the upper registers. Sound definitely fuller and cleaner.
