One remarkable thing I loved about working with Klaus was his ability to make just the right adjustments to the instrument after my having expressed only vague ideas. The result was a beautiful custom-made horn, crafted to my personal needs and wishes. Klaus has the ability to listen to a particular horn player’s sound and then to analyze the unique interaction between the horn and the individual player. It takes a true craftsman with a lot of patience to produce an instrument that is just right for you. .

I am very pleased with this Instrument! It gives me a lot of assurance and inspiration, and yields beautiful colours and very good projection. The sound carries to the back of the concert hall even when I play very "
This Bb high/F Horn is the ‘complete package’. It meets my personal needs and at the same time has the typical Fehr sound. It is a wonderfully free playing Horn with a beautiful tone and rich colours, both big and bright for the symphony orchestra and slim and very flexible for chamber music and solos. The high F horn flows effortlessly from the sound of the Bb horn, resulting in great agility when playing high passages. The sound is nicely balanced and rich in overtones. Making music with this instrument is a real treat.
15 years ago I tried a Kruspe F horn in Berlin. Its tone fascinated me so much that I decided to buy a single F horn. Now I’ve finally found one that blows just as freely as the old Kruspe. The overtones are perfectly tuned, the valves move lightly and the sound is just as I had imagined it would be. Finally, since the F horn is the direct ancestor of our double horn, I like to use it when teaching!
"Every time I played one of the Klaus Fehr horn I got serious doubts about changing my former instrument, which I really liked during the last 8 years I had been playing on it. I was always afraid I could lose my identity but a few months ago I decided to go for it. I asked Klaus to build a free blowing and a versatile instrument to play in a symphony orchestra, chamber music,... I always like the possibility of changing color on the sound in order to play with strings, brass, winds or just character in music, and Klaus got this really fast. He thought I would have to be back in Sibbe to do some adjustments after a while of playing but that wasn't necessary at all I found the horn I always wanted to have. Its tuning is fantastic and the balanced between all registers just perfect. No matter what your taste is, Klaus is willing to help you find what you are searching for and he really does a brilliant job.
I am freshly enthusiastic about Klaus Fehr’s Bb horn with each passing day. The well balanced sound, very fine intonation and optimal response have made the instrument my dependable partner, and not just in chamber music.I highly value the capable guidance and support Klaus offers, and am sincerely thankful for his superb craftsmanship!
For many years now I have been familiar with the horns of Klaus Fehr (I play on a double horn). For me his instruments have the great capability of sounding noble and generous, but at the same time they offer a pleasant agility in playing. In addition, they possess the stability, strength and power necessary for daily professional use.
I feel that it’s very important to have a similar sound in the Bb side of a normal double horn and in that of a double descant with high F. For the baroque and early classical pieces I use my single high F horn to get a brilliant, clear, and light sound. But here with Klaus Fehr’s Bb/high F descant horn I found the sound I had long been searching for: big, warm, and supple!!! Now I restrict the high F horn to making entrances in the high register easier ...The intonation is extremely good. Sound is even throughout the entire range. The instrument ‘speaks’ with a light touch, and has relatively little resistance for a Bb/high F horn.
“The Fehr horn blends well, never getting aggressive, and the high register remains stable and warm, mixing easily with the woodwinds or even solo violin. For me this is the big plus when compared to the horn I’d played for many years previously. The Fehr horn sound carries through a full orchestra fortissimo, but delicate playing is also heard very clearly in the hall. The most telling comment I received was that it sounds so easy to play.”
Lange tijd heb ik gezocht naar een mooie enkele Bes hoorn, die ik kan gebruiken als aanvulling op mijn dubbelhoorn, met name voor kamermuziek en het klassieke repertoire. De hoorn die Klaus heeft gemaakt overtreft mijn wensen. Het is een heerlijk soepel spelend instrument met een prachtige toon.
Hij voelt in alle registers heel soldide en trefzeker.
Dankzij de prachtig weggewerkte en afneembare F-pomp kan ik ook in het lage register het instrument inzetten.
Zonder deze pomp speelt het instrument nog wat lichter, waardoor de inzetbaarheid zeer groot is.
Ik ben erg blij met de hoorn en mijn dank aan Klaus is groot.
I have known Klaus for many years now, and I was allready a great fan of his horns when he first started developing and building them.
At the time I actually decided I wanted to have one myself, Klaus and I did a great deal of testing and experimenting together in his workshop. Changing the smallest of details in developing the perfect instrument for me. This process eventually lead to the ‘model 1’ in the current range Klaus offers (and wich was first presented in London in 2014 at the annual global conference of the international horn society.)
The former instrument I played was nice, but it somehow always limited me. As a member of the Netherlands Radio Philharmonic Orchestra I play a very broad diversity of repertoire. Therefore I am extremely pleased with this instrument since it makes it possible to play a great variety of different colours. Also I can play much more freely and it speaks so nicely equal in the whole range of the instrument. Furthermore it has such an enormous carrying capacity; both in the strong and most delicate passages.
Changing to this instrument really changed my profesional life and working with Klaus is also a great joy. In my opinion he is the best craftman in his field and in addition also just a really great guy.
The Klaus Fehr Single Bb blends well with double and triple horns, in both orchestra and chamber settings. It sounds easy and the tone is glorious in all registers. I appreciate the ability to manipulate the sound colour according to the requirements of the music. Mr Klaus has also been extremely patient and professional in the entire procurement process.
I met Klaus in July 2016, when i made a trip to Europe looking for a possibly new or any - in good conditions - used horn. Klaus showed me his horns and him and Wiebke were so kind with me. When i played his horns i knew they were just as amazing as him. They fit perfectly in every single ensemble that you can imagine. All the different colors you can get is just countless. Either in orchestra or chamber music, even popular music it will make you feel comfortable because it’s an instrument built for you, and that adapts to your way of playing and not upside down. Klaus Fehr horns are the best definition of quality, without a doubt.
I'm really happy with my new discant horn from Klaus, is very flexible and reliable, exactly what I need to perform in the high register. Soon I'll get also a big double horn for the regular orchestra playing and I'm sure will be as good as this one. Thanks a lot Klaus!

In 2013 heeft Klaus Fehr een hoorn voor mij gebouwd. Mijn eerste ervaring op het podium was Brahms hoorntrio. Ik was meteen verliefd op die hoorn. Na nog wat aanpassingen heb ik jarenlang met plezier in het orkest gespeeld en kreeg altijd veel positieve relaties van collega's en toehoorders. Klaus kun je rustig een hoorn fluisteraar noemen. Een Top vakman!
