The London Precision Model combines the slimmer Precision model outer geometry with our New London interior classic British bullet chamber design. As opposed to the heavy New London which accommodates a hard rubber alto ligature, the London Precision Model accommodates a standard metal tenor ligature such as the Selmer 404, (we recommend the Marc Jean Model 893). It is machined from Brass, meticulously hand finished and has a hard rubber bite plate. The obvious question of “how does the performance compare to the New London can best be summed up by the comments of a customer who insisted on trying both: “I cannot part with either the London Precision or the New London. They are the 2 best mouthpieces I've ever played. Although similar, they are also different from each other. The New London is less bright than the Precision, but still free blowing and sooooo easy to play. I can play most any style with it, but I feel it is best for jazz. The Precision is a bit brighter but has a certain "character" to its’ sound that is easy to hear but difficult to describe in words. Short story, I'm keeping both!” This mouthpiece now includes a ligature as well. The London Precision Model is finished in Rhodium plating or 24K Gold as an option. Available in sizes 7, 7* ,8 and 8* and custom sizes are also available upon request. As with all our pieces, they are extensively hand finished and some variation of “brightness” or “darkness” from profile adjustment can also be specified upon request.
Note: fulfillment time for any of our mouthpieces may take up to 4-6 weeks.

Sounds great. In retrospect I would have gotten a slightly smaller tip opening, maybe a 7* or **. The plating is a bit discolored which surprised me after only a few months. Love my HR London Model as well. I have been playing your mouthpieces for years. Thanks, Ted. LL
I have been playing a Hard Rubber New London and decided to try the metal Precision. It is a fantastic mouthpiece, blowing similarly to my HR but with more colors and very reed friendly I am playing a 7* using BSS red #3 Thanks for the awesome craftsmanship.
All Ted Klum mouthpieces are always fantastic, this one also.
I want to say "Thank you"

Ted Klum has raised the bar for bullet chamber mouthpieces. My King Super 20's have never had the low end response as they do now with the London Precision. I can whisper and be sultry and then I can blow hard and feel that the bell is going to implode! The tone is fat and thick when I hear and imagine that way and when I feel I want brightness and edge, it's there too. I.have some power pieces that I like but when it's time to go up against the LP, it seems that the Precision has an overdrive gear. The altissimo is blood curdling and It's easy for me to "slot" the pitch. I was fortunate that my sax buddy JB loaned me one of this two for a week because he knew I was wasting time and money buying vintage metal Bergs that never measured up to what I was looking for. I sold 3 mouthpieces to pay for my London Precision, I'm trying to figure out which of my five remaining tenor sax mouthpieces I'm going to keep for a backup.

Absolutely fantastic! Versatile, can be used in any musical genre! Easy to play across the instrument's entire range, perfect tuning, fast response, extremely rich sound! You can whisper delicate ballads or achieve great sound power with amplified guitars. As stated in other testimonials from other buyers, this is the best tenor mouthpiece I have ever played, among the dozens I have tried over the last 20 years! Thank you very much, Ted!
I've been playing tenor saxophone for years, and I've tried countless mouthpieces in search of the perfect fit. Finally, I've found it in the Ted Klum London Precision Model. This mouthpiece has completely transformed my playing experience.
The tone is simply incredible. It's rich, warm, and full of character. I've never been able to achieve such a beautiful sound before. The mouthpiece is also incredibly responsive and easy to play. It feels like an extension of my own body. The versatility is amazing. I can play everything from ballads to bebop with ease.
If you're looking for a mouthpiece that will take your playing to the next level, I highly recommend the Ted Klum London Precision Model. It's a game-changer.
Thank you Ted for your amazing work.
This is the BEST Tenor Sax mouthpiece I have ever played on, and I have owned and played on many. Thank you for offering such Precision made mouthpieces Ted. My only regret is that I have not purchased one sooner. This mouthpiece does everything that anyone could possibly look for in a mouthpiece and it does so effortlessly. This has truly been a joy for me to play. This one can do it all. A very versatile mouthpiece.I also appreciate the fact that you were able to brighten it up a little for me. Very responsive to many reeds too.
Thank you again Ted!
Absolutely the best tenor sax mouthpiece I have played in 20 years. It has it all for you to perfrm in all musical genres. A unique and priceless piece of craftmanship.
Hi Ted
I received my new London precision mouthpiece on Friday and already took it to a gig the next day and allI can say is WOW!!! what a fat sounding piece, the altissimo was effortless and the high notes were fat also. I have been one mouthpiece guy for a long time but this one changed it for me, very happy customer here and thanks for the speedy delivery.
My mouthpiece search is finally over, the London precision tenor is everything you would want in a mouthpiece- Fat, easy on the altissimo, the bottom is big and fat, I just can`t describe how awesome this mouthpiece is, I`m one mouthpiece guy, the London precision just took my sound to another level, Thank you Ted!!!!
Just want to say "thank you," to Ted Klum for this gorgeous new mouthpiece. It arrived yesterday & I really haven't been able to stop playing it! I'd been using his Tonamax .118", model since 2013, played that with both Pat Martino and the NewLight project with Liebman/Perla/Nussbaum...
and this new London Precision Model? I asked him to make me a .120" (or a size 9 in Link terminology) Mind you, I've only had it for 24 hours 'n change... but?!!!
Ted has created something unique, here. It has the Bullet chamber / a gorgeous baffle, and this curved "duck bill" beak area for the teeth (very comfortable) all cool characteristics one would associate with a Berg Larsen. A different kind of shank than any other mouthpiece I've ever seen. It's actually not really like any Berg Larsen I've ever played! This gorgeous piece of Brass still possesses all of the flexibility in tonal qualities I've loved about my Links... along with this direct focus and power.
Gotta play one and feel what I'm talking about. But a .120" tip piece with a fresh new out of the box #4 reed? And the horn vibrates like crazy in your hands - while the sound is not bright. It's dark, and very present.
I'm not really a video on social media guy, but will try to grab some footage of me using this new Mouthpiece with Gene Perla and Bill Goodwin, tomorrow night.
And once again, Thank You, Ted Klum @ Ted Klum Mouthpieces, LLC
