Kessler Custom Bass Clarinets

Kessler Custom Bass Clarinets have become hands down the best selling instrument in our store… not just bass clarinet or clarinet, the best selling instruments in our store. Think about that for a second… a bass clarinet?! Bass clarinets should never be a best selling instrument in any store unless all that store sells is bass clarinets!! So what makes this instrument so popular?

The answer is simple… they offer the perfect blend of what most players are looking for: performance, quality & affordability. Let’s look at each one to understand a little more behind this:


Kessler Custom Bass Clarinets offer a performance level more in line with professional models due to the combination of advanced features and acoustic design. On the features, the Kessler Bass Clarinets all offer a double register mechanism which helps to balance the tone & pitch throughout the registers. The double register mechanism is a lifesaver for the instrument and one of the key features that differentiate the Kessler Bass Clarinets from traditional models in this price range.

The acoustic design affords a free-blowing yet rich tone. Combined with our new “Gen 2 Plus” Setup, these instruments give a truly balanced, rich tonal response and even voicing. They have served in every musical environment from the band room to Broadway shows!


All Kessler Bass Clarinets are made in a factory that we have used for over 20 years. The instrument has exceptional tonehole manufacturing to ensure a proper pad seal and reliable performance. The keywork is well crafted and fit to the instrument to provide smooth feel and reliability. The pads are Pisoni leather pads from Italy which are the industry standard for quality and reliability. Furthermore, every instrument is setup in our ProShop to ensure it meets our standards.

The synthetic body gives a light weight while still helping produce a sweet tone. The light weight helps make the bass clarinets easier to handle and improves overall responsiveness.


This is the lynch pin of the whole operation! The lineup of Kessler Custom Bass Clarinets offer a price point that is commonly associated with only entry level student models that do not share in the feature, performance, and in many cases the quality level being offered.

In the end, bass clarinets, even student models, are not cheap. The combination of performance and quality at a student accessible price makes our bass clarinet lineup the most impressive value on the market.

Now with “Gen 2 Plus” Setup!
In late 2021, we began experimenting on a more advanced setup to our Low C Bass Clarinets. While the instruments were already great instruments, we found that some of the most discerning players were seeking even a little more out of our bass clarinet. Our new “Gen 2 Plus” Setup involves more time in our shop of course which led to a small price increase, but the end result is marked improvement in performance in several of the more problematic areas on the bass clarinet.

This new setup includes additional tonehole undercutting & custom key height adjustments to improve tonal voicing and response specifically in the right hand of the instrument helping to further improve the acoustic balance of the instrument. This new setup is standard on all of our Kessler Custom bass clarinet models as of January 1, 2022.

Build Your Setup

Build Your Custom Setup

Your mouthpiece, ligature and reed setup are equally important to the overall performance. For this reason, we allow customers to build the setup that they want rather than building a “stock” mouthpiece setup in to the cost. So you can choose from a wide array of discounted mouthpieces from Backun, Fobes, Selmer Paris & Vandoren as well as ligatures from Bonade, Rico, Rovner & Vandoren.

We also allow you to upgrade to the best bass clarinet cases in the industry, the BAM Trekking cases. The BAM Trekking cases are the most protective and versatile for our Kessler Bass Clarinets. They offer the right support and storage options for any performance level of musician.


Stock Accessories

As the years have gone on, we continue to make improvements to our bass clarinets. When possible, we make these upgrades available to our previous customers. These items are ONLY available to verified owners of one of our bass clarinets.


Financing Available!
