Kessler Custom 2nd Gen Low C Bass Clarinet
Affordable Performance & Quality
The Industry Standard for Value: the Kessler Custom Low C Bass Clarinet has earned its place as the single best-selling instrument in our entire shop. It is rare for a specialty instrument to outsell trumpets, flutes and saxophones, but this bass clarinet is the exception to the rule.
Why? Because we this isn’t a ‘cheap’ instrument, it instead offers a professional platform accessible to everyone. By prioritizing the perfect blend of Performance, Quality, & Affordability, we deliver an instrument that defies industry norms.
Gen 2 Evolution
We are relentless in our pursuit of improvement. While our bass clarinets have received glowing reviews for years, the instrument you buy today is even better than the one reviewed in years past. We have continued to refine the Kessler Custom platform with significant upgrades to ensure it remains the market leader in performance value. Some of the notable improvements since the 2nd Gen platform launched include:
- Enhanced “Gen 2 Plus” Setup: (Standard since January of 2022) We refined our setup process to specifically target the voicing across the break. While this process is more labor-intensive for our technicians, it ensures your instrument offers professional stability and response immediately out of the case.
- Custom Alloy Neck: (Standard since January of 2023) We upgraded to a new neck design featuring a specific alloy blend chosen for its acoustic properties. This heavier-mass neck produces a richer core tone and significantly improves clarity in the upper register. This neck is exclusive to Kessler Custom bass clarinets and is not found on any other model on the market.
- Premium Protection: (Standard since January of 2023) We ditched the generic “student” case for a custom-designed, professional-grade case. It offers superior impact protection and storage, so you can transport your instrument with pride and peace of mind. While other brands have since adopted this case style, we were the first to bring it to market, setting the new standard for protection.
Best of all, we achieved these upgrades without the massive price hikes seen elsewhere. Unlike competitors who have raised prices significantly over the last few years, we have maintained our commitment to affordability. We have no plans to change that. Even after the tariff instability of 2025, we fought to keep our increases as small as possible, absorbing much of them ourselves. As tariffs came down, so did our price to customers. In an economic landscape where everything else is getting more expensive, the Kessler Custom Bass Clarinet offers you more value than ever before.
Mouthpiece, Ligature & Case Add-On Options
Build Your Custom Setup
The mouthpiece and ligature are the “engine” of your instrument – crucial for overall performance. Instead of inflating the price with a generic stock mouthpiece you will likely replace, we give you the freedom to choose the professional setup that is right for you immediately.
You can bundle and save on a wide array of top-tier mouthpieces from Backun, Fobes, Selmer Paris & Vandoren as well as various performance ligatures to ensure your new bass clarinet plays its best from the very first note. If you need advice on any of these customized mouthpiece, ligature or case options, always feel free to give us a call!

BAM Case Upgrade
Our standard case (introduced in 2023) offers a secure, custom fit and is crafted from premium materials. However, we also highly recommend the BAM Trekking Series bass clarinet cases for customers. The BAM Trekking case offers great fit & protection overall to the instrument but is a little smaller & lighter case with a much larger external storage pouch. So we offer customers a generous discount when you bundle the BAM case with our low C bass clarinet at the time of purchase!
- BAM Trekking: $470.00 Upgrade – click here to view –
While BAM makes several cases, we ONLY recommend the Trekking model. The other models, such as the Hightech are great cases, but can put additional pressure on the register mechanism on the top of the body, thus putting it out of alignment. The Trekking case is molded differently and does a better overall job of supporting the instrument.
Stock Case Dimensions
The stock case measures 33.5″ x 9″ x 13″. With the bass clarinet inside of the case, it weighs 18.8 lbs.
Additional Information
Professionally Setup
Every Kessler Custom low C bass clarinet we send out to a customer is not released from us unless it has been completely setup in our shop first. This is because the setup on any low C bass clarinet is of the utmost importance! Sometimes, a clarinet (regardless of who the manufacturer or the price point is) comes in needing 20 minutes of adjustments and then the very next one can require 2 hours!
This is why we perform our setup (in our www.ClarinetRepairs.com ProShop) on your clarinet before delivering it to you. You trust us with your purchase and we want to make sure that you are rewarded by giving you your new low C bass clarinet set up flawlessly!!
Pads
Our 2nd Generation Bass Clarinets utilize a premium Pisoni made Lucien Deluxe Leather Pad. Our standard finished models utilize a traditional white leather version of this pad with metal, domed resonators.
International Order Information
Shipping a bass clarinet internationally poses a few unique issues that make it sometimes prohibitive. The main issue has to do with international customs inspection as the bass clarinet crosses in to your country’s borders. During this process, customs inspectors may open up the package to inspect that the contents of the package match the invoice declaration (so that they can make sure to collect the correct amount of applicable taxes). The issue is not in the inspection, but rather the re-packaging AFTER the inspection.
We take great care to pack our instruments for safe transport, but these inspectors are not required to re-package the instrument in the same manner. When re-packaged incorrectly, the risk of damage to the instrument in shipping greatly increases. The stock case that we released in Jan 2023 is now capable of international shipment and is actually our recommended model. However, we also can recommend the BAM Trekking case for international customers if they prefer, but there is a little more risk with the BAM case.
So for these reasons, we can only accept an international order if the customer is willing to accept the following terms:
-
- International Customer accepts full responsibility for any subsequent damage.Â
There is no way for us to properly solve damage / repairs for international customers due to the shipping costs internationally. Inside the BAM case, the most likely damage is the left hand F/C lever getting bent. This is a fairly inexpensive and simple repair for most technicians. To date, we have seen no damage in the stock case that we introduced in January 2023 - International Payment must be via Bank Wire Transfer
We unfortunately cannot accept international credit cards or PayPal accounts (excludes Canada). So any international order for our bass clarinet must be made via a Bank Wire Transfer. - Additional Import Taxes
Customer is solely responsible for any and all taxes, fees and other costs that are due as a result of international importation. These costs are calculated before delivery, by the delivery company. We can usually estimate these fees through our UPS software for you once you provide us with you shipping address and details of what you want to order. Please note though, these estimates are non-binding as we have no control over that process. These estimates do tend to be accurate as they are provided by UPS and UPS is who acts as the importing agent for you.
- International Customer accepts full responsibility for any subsequent damage.Â
Please note that accessories from Vandoren (mouthpieces, reeds or ligatures) and Selmer Paris (mouthpieces) cannot be included with an international bass clarinet order (due to manufacturer restrictions). If you would like to proceed with an international order for our Kessler Custom 2nd Generation Low C Bass Clarinet, please use the form below.
WARNING: This product (or finish option) can expose you to chemicals including Nickel, which is known to the State of California to cause cancer. For more information, go to www.P65Warnings.ca.gov.

Fingerings
Our Low C Bass Clarinet uses standard fingerings but obviously has additional keywork. Here are the additional keys and their function. Please note, when playing any of the key options for Low D, C#/Db or C, we recommend also using the Right Hand Pinky Eb so that you do not have all of the keywork weight and spring tensions being reliant on the one lower key.

First off, I want to say I really didn’t expect a $2000 instrument to play at the level of a Selmer. However this is exactly what Kessler and Sons has created. The altissimo register is very easy and clear, the clarion register is very smooth and resonant, and the chalumeau register (low notes) is very controlled. This instrument can be played very quiet or extremely loud while maintaining that sweet bass clarinet sound. It has the professional features of a double register key and an extended range to low C which both perform flawlessly. If you want to save A LOT of money but dont want to sacrifice ANY quality, I highly reccomend this isntrument!

I have had my Kessler Low C for three months now and I love it! I had my professor do a set up on it and there were a few minor leaks but nothing serious. Fixing those leaks did not change the amazing playability of this instrument! The chalumeau range beefy and the clarion register is very smooth. The finish is not the best but this is only cosmetic. I like the worn look so there is a plus for me actually! Overall, if you’re looking for a solid playing instrument whatever level you are because nobody really wants to pay 13,000 on a bass clarinet, this is your instrument.

The instrument was well packed and no damage was apparent from shipping. Corks did need quite a bit of greasing before the instrument could be put together. The instrument is smooth across all of its register and resonates well. Intonation is really good except on anomaly— the Low E which I have to lip up to bring into tune. Definitely would recommend over any Plastic Low E Flat Bass Clarinet, which are similar in price brand new.

This is a great instrument. I was looking for an inexpensive way to get a Low C bass clarinet, and the Michael Lowenstern review convinced me that this instrument was worth a try. Wow! I’m blown away at the quality of the Kessler Cstomer Low C Bass Clarinet , and will likely be letting it replace my Selmer Paris bass clarinet (to low Eb) entirely. It’s exactly as Lowenstern said — maybe better! Highly recommended.

I’ll be frank, this instrument is fantastic! It’s great for those who are beginning the Bass Clarinet. I’ve played on this instrument for a while and it sounds amazing! I already got the fingering down as it’s 99% similar to the Soprano Clarinet (Bb Soprano Clarinets usually don’t go down to low Eb or C). Literally, for anybody who is new to the Bass Clarinet, if the sound isn’t great it’s YOU, not the instrument. Came very quickly (that said I do live in Arizona), and was well packaged. At first, like most instruments, it does require a MEGATON of cork grease to assemble the middle piece, but that’s my only gripe about it. Definitely worth a buy!

I played bass clarinet in High School 20 some odd years ago. My father gave me a Yamaha YCL-622ii BC as a graduation gift. It was a lovely instrument, but it soon stayed in my closet gathering dust as my passion for music faded. Eventually, I sold it so I could buy a house (As you may know, those Yamahas could cover a nice downpayment). 20 years later, I picked up the bass clarinet again thanks to my girlfriend’s encouragement. I was borrowing horns she had access to and playing in our local community band, but I was missing something. I was missing the feel and the resonance of a low C Bass Clarinet.
On YouTube, I see Michael Lowenstern’s review of this Kessler Custom Low C Bass Clarinet, and I’m like “There’s no way this horn could be a little over two grand and sound this good.” I showed my girlfriend the video to see if this would be a good investment (She is the professional, I trust her judgment) and she was like “Wow, that sounds really good. If you get it, I’m going to have to borrow it!”
Pound for pound, this is a wonderful instrument at its price point. The clarion register is the best I’ve ever heard on a horn I’ve played. It comes out effortlessly. The lower register sounds meaty and tone wise, it’s stellar. I initially bought a Yamaha 4C mouthpiece for this (Since I had it with my YCL-622ii, I figured it would be OK), and Dave Kessler personally recommended that I try the Clark Fobes mouthpiece instead. Of course he was right. This bass clarinet is the best value for your money if you want to explore what a Low C Bass Clarinet can offer you or if you are a doubler. You can’t go wrong with the price point coupled with the excellent customer service.

I had bought Kessler’s bari sax previously and was blown away by the quality, tone, and ease of playing. Michael Lowenstern (if you don’t subscribe to his YouTube channel yet, go now…I’ll wait…) posted a review of the Kessler Custom Low C 2nd Generation. When he did a blind side by side test against his custom Privilege…just wow.
I own a competitor’s low C, which plays fine after over $1000 of overhaul (rods had too much play among other issues). The Kessler’s sound has a darker solid core, an even range from the low C to the altissimo G, and is free blowing. And the price is right. :)

I am extremely amazed at how well this instrument plays! The chalumeau notes are nice and beefy. The clarion notes are very smooth! The altissimo notes are amazing!! The keys are sturdy and well thought out. I highly recommend this horn!

Last week I received my Kessler Custom Low C Bass Clarinet – 2nd Generation!
As I’m not a clarinet player (been playing the soprano saxophone exclusively for 30 years and a bit of alto!) it took me about a week to get used to it’s fingerings and start playing decently in the clarion and altisimo registers and produce a good sound that I can enjoy.
My impressions so far?
I love this instrument!
It has a gorgeous and powerful sound and it looks great! It can play loud but it can also whisper.
The keys and mechanism are solid and working smoothly and without being noisy.
And as for my experience dealing with Dave Kessler was excellent from the very beginning. All his recommendations were spot on. The man knows his stuff and that was the reason I decided to buy from him, oversees with import taxes and extra shipping costs involved. Definitely worth it.
Overall I’m very happy with this instrument and I think it was the best choice considering it’s price.
The only “side effect” I’m having is since I got it I almost stopped playing my beloved saxophones and exclusively playing daily now this beautiful bass clarinet!

This bass clarinet has gone beyond my expectations. The tone is absolutely wonderful and the lower register is unbeatable. I was skeptical at first due to the price, but when I received the instrument, I was blown away immediately. It is a joy to play, and easy to play with a solid tone.
