Kessler Custom Artist Series Brass
Kessler Custom Artist Series Euphoniums
Professional Performance, Student Price

Kessler Custom instruments are designed with a singular goal: provide customers with affordable, quality instruments. We achieve this by working directly with factories to manufacture instruments to our specifications and thus eliminate the various middle men involved with the music industry. We then sell direct to the end consumer offering a superior performance level compared to the price. As a custom shop with an emphasis on repair, we know how to work with factories to make this happen and have been doing so for over 20 years. Our line of Artist Series Euphoniums are a perfect example of this experience at work!


At the core of the design of our Euphonium lineup is a true professional bore. Most student & intermediate euphoniums will use a bore based around a design that is easy to play, but fails to allow the player to grow in to the next phase of performance. This then forces the player in to a higher end horn later in order to achieve this. Some might argue that the “ease of play” of these more student based bores are more ideal for younger players, but we have found that simply to not be the case. Yes, students might play the student bore a little easier at first, but they also can play the pro bore with very little effort difference. So why not give them the better design on their first breath?! That answer is simply future sales. If their first horn is too good, what will ever make them upgrade?

We take a completely different philosophy by giving them the proper design tool to start with on day one, note one! Now the only decision is which configuration to go with: 3 valve, 4 valve or 3 valve compensating?


All of our Kessler Custom Artist Series Euphonium models are made side by side in the same facility. This factory partner has exceptional workmanship with tolerances of assembly that are higher than almost anything on the market. Every horn is still completely gone through in our ProShop to ensure that the instrument is in perfect working order and ready to amaze with the first note. We make sure that all tuning slides are fit properly and smooth (though we rarely have to make an adjustment as the factory fit is excellent) and that valves are aligned and free from manufacturing debris like lapping compounds that are commonly left on many horns. We further setup all of our horns with a premium light weight synthetic oil (LaTromba T2 is our favorite) for great action and durability. Finally, each horn is paired with a German CNC precision made 51D mouthpiece.


This is the lynch pin of the whole operation! The lineup of Kessler Custom Euphoniums 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, euphoniums, even student models, are not cheap. The combination of performance and quality at a student accessible price makes our lineup the most impressive value on the market.

Valve Configuration Pros & Cons

3 Valve Euphoniums
Benefits of 3 Valve Models
At the core of all euphoniums is the standard 3 valve design. All euphoniums can share the 3 valve fingerings regardless of the presence & function of a 4th valve. This is often easier for younger students as it is less complex. 3 valve models also are the lightest weight making the horn easier to handle. However, 3 valve models tend to be very basic student models in the industry. Luckily, the Kessler Custom 3 Valve model uses a pro bore & design so that this isn’t the case on our 3 valve!

3 Valve models also are more affordable since they are simpler machines.

Downside of 3 Valve Models
Euphoniums will go sharper in pitch the lower you go. This is due to a “math problem” with the pitch of the instrument. With each note you go lower, for proper intonation, you would increase the air column length by 6% from the previous note. So from Bb, A would be 106% as long as Bb. However, Ab would not be 112% but instead would be 6% longer than A, which would make it 112.36% the length of Bb. G would then not be 118% of Bb, but rather 6% lower than Ab making it 119.10% longer than Bb.

This intonation issue is the downside to a standard 3 valve model. Since each note has different fingerings and tuning slides in each valve, this math problem is accounted for until you go an entire octave with the same fingering. The lower octave is where this systemic math problem catches up with you. This is where 4 valve & compensating systems come in to play.

4 Valve Euphoniums
Benefits of 4 Valve Models
4 Valve models add an additional valve with its own independent tuning slide to address the “systemic math problem” discussed in the 3 valve model. This 4th valve allows the player to utilize a new set of fingerings for the lower register notes in order to get these notes into better pitch. So instead of playing low F with valves 1 & 3  for instance, you can use just valve 4 leaving 1-3 open.

Most “intermediate” models will feature a 4 valve configuration. However, most will still utilize an otherwise “student” design & quality level. Our Kessler Custom 4 valve model uses the same pro bore & overall design of our top end compensating model but in the traditional 4 valve configuration. So if you are used to a 4 valve but want a top end performing horn, you can get that with our 4 valve model!

Downside of 4 Valve Models
4 Valve models obviously have increased cost and weight from their relative 3 valve counter part. The player also has to learn a whole new set of fingerings to really utilize the performance benefit of the horn. So if a student starts out playing on a 4 valve, then they can learn these fingerings at the start of their playing career. However, if they learned on a 3 valve and then switch to the 4 valve, some students will not learn the new fingering and thus never obtain that advantage that their horn can offer. So it is up to the player to learn their instrument!

4 Valve Configurations
4 valve models can be found in two different configurations: in-line 4 or an off-set 3+1 (non-compensating). The in-line 4 valve is the more common as it puts the 4th valve in the row with the other 3. This means the 4th valve is operated with the player’s pinky. There are also models that will place the 4th valve of to the outside edge of the 3 valve cluster in what is known as a “non-compensating 3+1 configuration”. This is specified this way as this is still a 4 valve model, not a compensating model and the fingerings are still the 4 valve fingerings. However, instead of the right hand pinky operating the 4th valve, the player uses their left hand to operate the 4th valve. This can help smaller players operate the 4th valve easier.

Compensating Euphoniums
Benefits of Compensating Models
Compensating models are 100% a 3 valve euphonium. You would utilize the same 3 valve fingerings throughout all the registers. The horn is then equipped with a 4th “Compensating” valve that would be in the 3+1 off-set configuration. This compensating valve sits on the outside edge of the horn and is operated by the player’s left hand. This allows the player to maintain the 3 valve fingerings, but when playing in the lower register, they can add the compensating valve to the fingering. This adds additional length to the air column by re-routing the air back through the valve casings and an extra, smaller set of slides, to “compensate” for the “math problem” of the pitch inherent in 3 valve models.

The weight of the instrument is also impacted on the performance of the instrument differently than the 3 or 4 valve models, giving the horn a little richer core to the sound in the lower register compared to the traditional 4 valve models.

Downside of Compensating Models
Compensating models are the most expensive option. They have an entirely unique valve cluster and so there is less cross-model parts meaning that factories have to make many more parts that are unique to the compensating model. Even the #1-3 valves and their casings have to be larger, unique parts due to the extra tubing employed on the compensating concept. However, the compensating design has become the standard for all top end professional manufacturers due to the superior intonation and response.
