KB Sax Handcrafted Saxophone Necks


Inspired by the resonant, colorful sound and the tonal flexibility of the legendary Selmer saxophones, the Super Balanced Action and the early Mark VI.

Our necks are handcrafted in our shop in NYC and are custom fit to vintage and modern saxophones.

They were developed in our shop in New York City with feedback from many of the top sax players in the world during a 1 ½ year prototype period, and our R&D is ongoing

A saxophone's neck has a greater impact on the instruments performance than any other part of the horn. The neck is where most of the sound color, intonation, tonal feel and flexibility is created.

By using a KB Sax handcrafted saxophone neck, you are getting a product that has been designed to optimize the performance of both modern and vintage horns from the moment your air enters the instrument.

Our necks are not merely replacement necks. Most players feel they are a clear improvement over their original necks, be it on Mark VI, Yamaha, SBA, etc.

Neck  Models

The KB Sax handcrafted saxophone necks come in two different models: Vanguard and Redwood.
Within these models, there are different metals available, each of which have their own specific sound and response characteristic.




The Vanguard has been developed to have the core focus situated in the high mid-tone area resulting in a slender, highly centered tone with a very resonant quality and a really strong projection. It is very quick responding, has incredible dynamic range and retains the same precise intonation as the Redwood model.

The Vanguard necks are close in sound and tonal response to the later Selmer Super Balanced Action but with the added benefit of precise intonation, easier produced and more stable altissimo range and a sound quality that is very consistent from top to bottom.

We are making the Vanguard in different metals: M-61 brass, hand hammered copper, bronze and hand hammered bronze

We developed a heat treatment method (precipitation hardening/“aging”) for the specific M-61 alloy which allows us to harden the neck tube and bring out the exact tonal color of this metal. The result is a neck with a very smooth frequency curve and a concentration of sound in the high mid-tone area.


Sound characteristic:

The Vanguard M-61 brass is our most mid-tone focused neck. The sound concentration is in the high mid-tone frequencies resulting in a very punchy and direct feeling neck. It is the neck of ours with the most back pressure/least free blowing (a very good kind of resistance - reminiscent of an 86,xxx Mark VI) which makes the articulation feel quick, the tonal feedback feel narrow and shapeable and enables a huge dynamic expressiveness. You experience that all your energy goes into activating a highly resonant and tight beam of sound.

We are using a process of hand hammering the copper neck tube after it is formed. It serves several purposes: It hardens the metal, making it as strong and pull-down resistant as a brass neck and it also give the neck its specific tonal sound and response characteristics.


Sound characteristic:

The Vanguard hand hammered copper has the same mid-tone focused qualities as the M-61 brass. It differs by having slightly less resistance and feeling a little freer blowing. The sound is rich and complex with some added lower mid-tone color, yet retaining the strong resonant projection of the Vanguard line.

We developed a specially timed heat treatment of our bronze (tin-copper alloy) that ensures high tensile strength and resonance.


Sound characteristic:

The Vanguard bronze retains the strong mid-tone core sound and focus of the Vanguard model. It is the most free blowing and "spread" playing in the line. It is brighter than the Hand Hammered Copper although there is a certain warm sizzle combine with the punchy focus that is highly reminiscent of the more focused of the early Mark VIses (like mid 80,xxx).

Hand hammering our Vanguard bronze neck tube compacts and hardens the metal and brings out specific sound and response characteristics.
Sound characteristic:
The Vanguard Hand Hammered Bronze is our brightest neck. The brightness is perfectly balanced out by the rich mid-tone presence. It is the least resistant of the Vanguard necks yet retains the strong core projection of the line. Very powerful and resonant and reminiscent of the best of the mid-period SBA necks.



The Redwood line is our original KB Sax neck and was inspired by the sound and tonal feel of the early Selmer Super Balanced Action. It features a colorful mid-toney core sound that maintains a powerful focus from the bottom of the horn and throughout the altissimo range as well as at any dynamic level.

Compared to the Vanguard line, the Redwood necks are slightly less mid-tone concentrated and feel a little more open and spread. An analogy would be the difference between early Super Balanced Action (like Redwood) and late Super Balanced Action (like Vanguard).

We make the Redwood in C-69 brass and Hand hammered copper.

The Redwood C-69 brass has a weighty and round core sound. Your air is channeled into a tight yet robust tone feel that makes the horn feel quick and compact in the lower range while maintaining the strong and present core sound without changing character as you move through the palm keys and up throughout the altissimo range.


Sound characteristic:

There is a great clarity and direct presence in the Redwood C-69 brass. It stays incredibly round and centered at all volume levels and while it is a focused neck it has a multidimensional or layered sound quality. It has the most core-weight resistance of the Redwood line which enables great tonal formability.

As with the Vanguard, for the Redwood Hand Hammered Copper we are using a process of hand hammering the copper neck tube after it is formed. It serves several purposes: It hardens the metal, making it as strong and pull-down resistant as a brass neck and it also give the neck its specific tonal sound and response characteristics.


Sound characteristic:

Compared to the Redwood brass, the Hand Hammered Copper is a more complex sounding neck with the dominant core sound being slightly darker. There is a smooth brightness with warm undertones. Where the Redwood brass has a very straight and direct sound column, the Hand Hammered Copper is more complex and rich sounding.


Our necks are sold in different brass alloys, in copper and bronze. Upon completion, we add a coating of a special wax. The wax can be reapplied if you wish to retain an unlacquered raw/bare look. If no additional treatment is done, the neck will over time take on the natural patina of the given metal.


We also offer a clear lacquer finish on any of our necks to preserve the raw brass, bronze or copper look. Additionally, we offer all models in various platings (gold, silver, brushed silver and others). Please contact us for more information.

Custom Fit

KB Sax handcrafted sax necks custom fit gauges
KB Sax handcrafted saxophone necks custom fit gauges

  For US customers:

To ensure the best possible fit when you try a KB Sax handcrafted neck, we have designed a set of tenon receiver measuring gauges. They are sized in 0.001” (one thousandth of an inch) increments. When ordering a neck, simply tell us the brand, model and serial number of your saxophone and we will send you a set of three measuring gauges, 0.001” apart. With these gauges, you can then measure the exact size of your tenon receiver and notify us which one fits best. Once we receive the gauges back from you, we will ship you a neck that has a tenon specifically sized to your horn. There is no shipping charge for the shipping and return shipping of the tenon receiver gauges.

  For International customers:

When ordering a KB Sax handcrafted neck, please tell us the brand, model and serial number of your saxophone. It is helpful if you can have the tenon of your current neck and/or tenon receiver on your horn measured by a professional. At this point in time, we do not ship our tenon receiver measuring gauges to international customers. We will send you a neck for your saxophone based on the information you provided us with, but you may have to have the neck fitted by a professional in your area to ensure a perfect fit.


Neck Making Process


The KB Sax handcrafted saxophone necks are made in a unique and innovative way.

Traditionally, a saxophone neck is made by forming a metal sheet around a mandrel to create a conical tube. The tube is then bent over a form to give it the specific shape of a saxophone neck. Some parts of the metal are stretched much more than others, resulting in a neck which has varying wall thickness.

The KB Sax handcrafted necks on the other hand, are made by stamping out the two halves/sides of the neck, which are then silver soldered together to create the neck tube. This results in a neck tube with a much more uniform wall thickness throughout. We believe this is part of the reason these necks sound and feel so resonant compared to other necks.

KB Sax handcrafted saxophone necks

By maintaining tolerances of +/- 0.002” (two thousands of an inch) throughout production, we ensure consistency in quality and sound. By keeping all the production in house, we have 100% quality control and we play test each neck extensively to ensure it meets our standard.

“I was shocked by the focus and power of these necks when I first tried them. Paradoxically, they felt both wider and more directed than my Mark VI neck. I must have played nearly 20 necks that first day, and every one was better than the neck I'd been using. I haven't looked back!”

“The KB Sax 'Redwood' neck is one of the best necks I've ever played. There's an ideal blend of high/mid/lows with a warm emphasis in the mid range that produces a wonderful array of colors. Lovin' it! Home run!”
