Michael Beert,

"This cello bow endorsed by Michael Beert incorporates Berg Bow's latest discovery, the use of Stabilized burled Rosewood for the frog, which has faster sound velocity and enhanced sound delivery from the bow, the greatest bow discovery in 100 years! Please read Michael Beert's endorsement below ."

"I have had the distinct pleasure of playing on two bows made by Michael Duff. The first one I used when I performed the solo to Richard Strauss’ Don Quixote with the Rockford Symphony Orchestra. I loved playing this bow as I was able to project all the way to the back of the hall and yet have all the nuances of a fine French wooden bow.  The variances of colors Michael Duff’s bows offer me are almost endless.  "

"More importantly, having soloed frequently with his bows, I know there will always be a consistent sound from frog to tip without any give or slip in the sound. It’s just 100% consistent from one end to the other!"

"Having had such great success with one bow, I dreamed up the perfect bow and commissioned Michael to build it for me. He was fantastic to work with: color, material, weight and balance - all aspects were discussed and agreed upon easily. His use of compressed hardwood for the frog and tip made the sound even more enhanced. In regard to craftsmanship, having played and owned bows from several contemporary makers over the years, Michael ranks as one of the top makers in the world and in my opinion, a bow that every student or performer needs."

"These are bows that I always go to for solo work, chamber music or orchestral playing. Their consistency in any setting is amazing! I cannot say enough great things about my experiences with Michael Duff and I strongly recommend his bows to any serious student and professional as they are a joy to own and play!"

Richard Biaggini,

" I have been the owner of a Berg violin bow for over 10 years. When I was in search for a new violin bow I was fortunate enough to be reintroduced to the wonderful Berg bows."

"As a concertmaster, I was looking for a high performance bow and decided to rediscover the Berg line because of the continuous innovation and advancements that I had heard so much about. Needless to say, I was not disappointed. While all of the bows are of high quality, I found that the Tourte-Voirin was articulate and effortless. Mr Michael Duff, the artist behind the craftsmanship of the bows, invests much research, knowledge, and refinement into each bow. He does not merely attempt to replicate a classic bow. Instead, he rediscovers and improves a classic piece of art through the use of modern science, while adhering to the application of traditional working methods. His experience has allowed him to create great composite bows that retain the qualities of a classic bow while producing better stability, flexibility, and consistency. His green innovations of stabilizing natural hardwood is the perfect example of this. I am continuously impressed by the Berg bows and cannot wait to add another bow to my collection. I highly recommend them to my fellow musicians. "

" I recently became the owner of a Berg Bow and have two students of mine at the Jacobs School of Music at Indiana University who have been thoroughly transformed as players with their respective Berg Bows. "

"What is in a bow? If you put aside the actual recipe of materials and craft in making them, I am referring to the chemistry between speed and weight of the bow arm with the bow, the sense of how it makes contact to the string and the resultant tone singing out from the violin. The bow is a player's communion with an immense language of sound possibilities. It can drive the grammar of articulation to new heights by how its innate balance grips the string and releases it. It can give depth at many expressive temperatures that can fulfill the player's imagination of what is possible and even take it beyond. "

"My Berg Bow has opened up yet another avenue in how a bow can handle in my hands. I have learned to not be surprised what a bow can offer you. The Berg Bow's particular strength is a calm and steady pull right from the time you put it to the string. With this physical sensation comes a fullness of tone production and ease in movement from frog to tip, as though the arm never really cantilevers as it moves to the tip—the contact remains steady and sure throughout the stroke. The spiccato 'sweet spot' is in a comfortable location and produces a buoyant rebound of all varieties of weight."

"It was an effortless musical relationship when I put this bow to the string for the first time and felt the way it coaxed the quality of sonority into being and easily spoke in a variety of articulations. What more could one hope for on a first date?"

Amy Barlowe,

" The gold fleur-de-lis Tourte-Voirin bow you have made for me is exquisitely crafted. Not only is it beautiful to look at, but the balance is wonderful. Its versatility enables it to draw a clean, lively sound with the flexibility I need for early classical and baroque playing, while it can deliver the warmth and color desired for other periods. Thank you so much for all of your care and masterful workmanship!"

With all best wishes,

Uli Widmaier,

"The gold viola bow arrived yesterday and I played it for 2 hours last night.You have outdone yourself. it is an unbelievably sophisticated piece of equipment. It is light, smooth, and elegant, but is has immense bite and power. I have two good viola bows - a Watson and a John Norwood Lee. There is simply no comparison at all. The overtones this bow draws out of the instrument are downright startling. It permits a freedom of movement that I have not experienced before. The bow changes at the frog are extremely smooth, and there is all the power in the world at the tip. I had no idea that my Curtin viola was capable of such sounds. The bow absolutely unlocks the instrument. Also, it doesn't hurt that the bow is drop dead gorgeous to look at. If I were a world-class viola player that is the bow I would covet. Thank you, Michael, for making this dream of a bow for me."

Dear Mr. Duff,

"Thank you so much for my two wonderful Berg cello bows. I use my bows for all types of playing; orchestral, solo, and chamber music. Both bows are superior to my wooden bows. The Berg bows produce more sound and make every style of bowing easier to execute. The Berg bows are also perfect in our tough Florida climate. Their superior performance remains consistent even through sudden changes in temperature and humidity. "

"I am happy to recommend the Berg cello bow."

Dear Michael,

"The bow did arrive this afternoon and I just tried it for an hour or so. It is quite a bow and what stands out right away is its flexibility making dynamic and colour changes very smooth and easy. Allows for more subtlety and range in expression. Next is that it tracks so well and there is not the slightest lateral instability. Third I find off the string and martele bowings much easier. Fourth : it definitely gets more volume out of this violin than any of my other bows. That's my first impression."

"What a great bow. Still much more to explore. Am going to be busy playing the next few evenings. Then off to Ottawa for a course and seeing my luthier Guy Harrison who was also interested seeing the bow , as well as some friends also violinists."

Hi Michael,

"Thanks again for the great bow. It's like driving a Ferrari : sticks to the string when needed and can bring out so many nuances instantaneously with very little effort. Haven't felt like playing my other bows since."

"All the best."

Dear Michael,

"I have been the proud owner of a Berg violin bow for the past 10 years. It has proven to be a very strong and reliable bow throughout many solo, chamber, and orchestral concerts. Recently, I decided to add the Tourte-Voirin bow to my collection and it is impeccable. I immediately fell in love with the bow's ability of having ease and flexibility while also demonstrating strength and balance all at the same time! I am very impressed. Your Tourte-Voirin bow evokes and shapes a vast range of elegant colors from my violin, which adds to versitility in playing. As Concertmaster of Orquesta Sinfonica Nacional de Colombia, I am both honored and delighted to be playing with your prestigious Tourte-Voirin bow in my future concerts and recitals.Your craftsmanship is amazing and it is clearly evident that your artistry has only improved to create such fine and detailed pieces. I will definitely be referring my fellow collegues to you and it is without reservation that I highly recommend your bows to all fellow musicians."

"Michael, I sincerely thank you for your excellent craftsmanship and dedication. I will be in touch with you for future maintenance of your beautiful bow."

"Dear Mr. Duff, I am a proud owner of one of your bows and I have to say I love that bow so much. I refuse to use anything else. I just wanted to touch base with you because I need to get my bow rehaired. At this moment I am living in Taiwan so I will be back in the U.S. in March for a few weeks. Could you please tell me how much it costs to get rehaired? How long do you need to do this? Since my time is very limited, I want to see if I have time this time when I am back in the U.S. Thanks so much for all your help. It is good to see you are coming out with more beautiful designs for your bows. They look breath taking" :)

"Michael Duff creates bows that are the fruit of greatest scientific knowledge, wonderful craftsmanship and, above all, artistic intuitiveness of the highest standing. For many years I have been a proud owner of a Berg bow and play it all the time. The beautiful finish and incredible wood-like appearance of the stick, the elegance of the fittings and, most importantly for a performer, the purity of the sound, the balance and overall playability, make my Berg bow a highlight in my collection. It is one of the best balanced bows I have, a real "extension" of my right arm. I believe that instruments of this quality represent the best alternative to the greatest, yet extremely expensive, vintage bows out on the market. Highly recommended!"

Concert Master of Cincinnati Symphony

"Michael, I am writing this to thank you for the superb Tourte-Voirin model Berg bow you crafted for me several months ago. I am continually stunned by the beauty of the stick itself, but more importantly the amazingly resonant and focused sound it produces. The bow is absolutely reliable in any and all performance situations and its amazing qualities have been noticed by numerous of my colleagues. I can honestly say it is one of the best bows I have ever played…period. Since purchasing the bow in the summer of 2010 and some 30 solo, orchestral and chamber concerts later, it has become my main performing bow and I expect it to remain so for a long time. Thank you for your expertise in crafting such a superb bow…it is the perfect match for my 1845 J.B. Vuillaume violin. I couldn’t be happier!"

"Dear Michael. I am writing to say how pleased I am with the Tourte-Voirin viola bow that you recently made for me. It really is such a "complete " bow with amazing qualities. I feel that there is nothing that it cannot do and I am being treated to a "in-service training course" where the bow is teaching me how to unlock it's secrets. Such stability and smooth legato, combined with instant attack and a reliable spiccatto, makes for a hugely rewarding bowing experience. I get excited every time I take it out to play. Thank you so much, I am your fan for life."

"I like very much the new Tourte-Voirin model Berg bow. It has an old wine sound and dances like the finest etoiles. All the Beaux Arts are contained in this remarkable violin bow. My colleagues at the conservatory say that one would have to pay 40,000 to 60.000 euros in Germany to find a bow like that. It is simply incredible!! Thank you for putting your heart into it Michael."

" The first time I came in touch with a Berg bow was with a violin model. I immediately fell in love not only with the beauty of the work but also with its incredible sound. I had to wait a few years before I could order one. My Delux model is as fantastic and reliable as I expected it to be and has made me the happiest of players. Its sound, clear - powerful and beautiful - and its versatility in all ranges and types of playing makes it the perfect bow for me. I don't exaggerate when I say that this is the best acquisition I have made in my many years as a player."

" I have been the proud owner of beautiful gold Fleur-de-lis Berg violin bow for many years and have been extremely happy with it. However, the new 'Tourte-Voirin' model which I commissioned recently is really astonishing. Its special flexural and sound quality is as good ad most great French bows that I have performed with. It excels in its remarkable steadiness on the strings.

I couldn't be happier with its qualities! It is also a stunningly beautiful looking bow, superbly crafted."

"I have been playing Berg Bows since 1985 and have many of them in my bow collection. The latest model is quite remarkable. I first played it this past summer (2009) and after a few minutes I was in love. It felt completely natural and it was capable of doing anything. Also it looks very beautiful and is superbly crafted."

"I am the happy owner of two deluxe Berg viola bows, one silver and one gold, made for me by master bow maker Michael F. Duff in Bloomington, Indiana.

I consider it a special privilege to be able to collaborate with living masters who create "tailor-made" violas and bows to suit my style of playing and personality.

Michael and I have been "talking bows" for over twenty years. IN the beginning he asked to borrow my fine Sartory and Vigneron bows for analysis and study.

Berg bows are made of special resins molded into bow shape under high pressure and temperature. For the viola bow that I commissioned I was able to meet with Mr. to discuss important details of the hand finishing, for example, weight, balance, and especially the head, which he shaped according to my wishes.

Because of Mr. Duff's mastery each of his bows is made unique. They look just as beautiful as my precious old pernambuco wood bows. Berg bows make a wonderful deep rich sound, and handle all styles of music superbly. I play my gold mounted Berg bow with great pleasure every day."

The sound is very beautiful, and the bow has great balance. It always does exactly what you want it to, resulting in clean crisp articulation. I love performing with it."

"Dear Michael, my Gulli-model deluxe Berg violin bow, which I ordered from you in 2006, is doing wonderfully well. It is far - and I mean FAR -superior to my Sartory, not only in handling but also in sound production. I have completely stopped using the Sartory, and I will probably sell it.

My daughter now needs a really good violin bow as well. There is no alternative to your bows. Therefore I would like to order a deluxe one from you, for her."

Uli Widmaier

Eduard Melkus of Baden Austria

"Michael, Your new Tourte-Voirin model Berg violin bow arrived today-it is a wonder-a true fairy bow, it dances over the strings. It produces the sweetest sound from my violin. Should I refer to it as “ He” or “She”? I prefer “She – I find her like a ballet primadonna – a Margot Fontain of bows, or a Nureyev, in which case I shall I shall use “He”. The mail took me by surprise, but what a pleasant one! I have never experienced such a delight in meeting a new bow and have played many fine bows over my career. As you know, for over twenty years I have performed with only your bow, which I bought in Exeter, England. Meeting the new one today was such an inspiration that I at once tried all sorts of sophisticated bowings, and it worked immediately on all. I can’t stress too much “His” beauty, this is evident with all of your bows. Did I tell you that the distinguished German violin maker Schade from Halle (the famous Handel city) did not believe me when I told him your bow was not pernambuco wood! Back to “His” or “Her ’qualities – she is like a younger sister to my older Berg bow, dancing over the strings and giving fun, joy and pleasure. Michael, I have never in all my life written anything like this, not about any bow, or violin, but with your surprise parcel I became really enthusiastic and had to write from my soul and heart. I have already decided to go on playing and concertizing , just to enjoy for a longer time my new love! THANK YOU! God bless your hands and your genius. "

Ever your Eduard

David Matheu Haskell - Bell of Spain

Former student of famous violist Rivka Golani

"Michael I performed an orchestral concert with my new bow just ten minutes after receiving it. I really think it is an excellent bow, able to bounce clearly and escape fast from the string. It produces a deep and earthy sound, a "paste" sound we violists would say. Many thanks for your excellent work. The final result is much better than I ever expected. "

David Matheu Haskell

Yohei Nakajima

"Thank you very much for the new bow I received it last week, and I absolutely love the bow. It has fantastic flexible control and any bow strokes are easier and more brilliant, and can create many more different color in sounds. I just love the bow.

Also good news,, I won a chamber music competition (in String Trio) yesterday with the new bow! It made a fantastic sound and created wonderful music.

I will recommend the bow to all my friends, musicians,,, "

"The Berg Bow is fully equal to the bows of the French masters, both in appearance and performance quality. I have played my Berg Bows under all conditions; orchestral, chamber music and solo concerts. They have excellent balance, fast response, very clear articulation and well focused, big sound. It is of great merit that one can choose a Berg Bow with the weight and resilience to satisfy personal preferences."

Peter Schaffer

Emanuel Borok

Soloist & Concertmaster,

"I have had a Berg Bow for many years and have enjoyed playing it as Concertmaster. I cannot deny that one of the pleasures it gives me is to see the expression on people's faces, when I tell them it isn't pernambuco. Not to mention the sense of security, safety, and increase of zeal I get when I see the notation, 'col loegno,' in my orchestral part."

Igor Ozim

Soloist & Professor of Violin,
Hochschule, Koln, Germany & Conservatoire, Berne, Switzerland

"The Berg violin bow is particularly good at all off string bowings, like staccato or ricochet, due to its clean articulation. It is fully equal to a fine French bow. I have been playing my Berg Bows with my Stradivarius violin in my concerts in preference to three magnificent F. Tourte violin bows."

Igor Ozim

Gerald Fischbach

Director, International Workshops & Professor of Music,
University of Maryland

"The Berg Bow is an extraordinary breakthrough. Mr. Duff recently sent me two bows. One reminds me of a fine Voirin in the way it embraces the strings; the other one is more Pecatte-like in its articulation and feel. I bought the "Pecatte". Both exhibit an almost startling lack of idiosyncrasy in response. The bow arm is liberated from the continuous little compensations for a shiver here, a thin spot there, that we've come to expect to deal with, even with the finest bows. This is not a bow you have to get used to; it inspires confidence and relaxation. From the first stroke you understand that it will do what you ask it to. The Berg Bow offers a highly centered, clear voice of great integrity & expressiveness. I enjoy working within its world of sound and especially appreciate the easy strength of its voice in the upper quarter, where so many bows thin out in sound."

Gerald Fischbach

"My Berg violin bows are the bows of my dreams. They have no performance limitations, responding immediately with their bigger brighter sound, which is equal from the frog to the tip. I find that their reliability engenders greater relaxation and freedom and therefore improved sound making and left hand technique. I have put my fine gold mounted Sartory away forever because it no longer satisfies me. Now I play my Berg Bows in recording sessions and in concerts all over the world."

Isidor Saslav

"My Berg violin bow is absolutely amazing, astonishing and incredible. This bow is an absolute godsend - I can't imagine a better one made by anyone. The sound that this bow draws in the upper quarter without any extra trouble or pressure has to be experienced to be believed. It effortlessly produces a beautiful focused tone which is even in quality from the frog all the way to the tip. It has exemplary quality in the special bowings and delights and astonishes the performer constantly."

"I have been performing with my Berg violin bow for some years now and I can highly recommend it. It excels in spiccato, sautille, ricochet and in cantilena as well. In the former bowings it jumps effortlessly while in cantilena passages it is very steady on the strings."

' I am delighted that Michael Duff of Berg Bows has recently begun to release his viola bows after years of design and experimentation. I find that they compare with fine pernambuco bows costing much more. In fact it is rare to discover a modern bow which brings out the best in the finest modern and old instruments alike. The Berg viola bows succeed admirably. Bravo to Mr. Duff for adding these beautiful bows to his eminently successful bows for violin and cello.'

"It is a pleasure to use my Berg Bow. Although Berg Bows are commended especially for their playability it is the sound of the bow that makes me love it.

William Conable

"I want to tell you how excited I am about the bow I bought. Things that had been difficult to control before, just popped out so clean and easy I couldn't believe it. Last week, I played a recital and many people who have heard me play for years raved about my sound - including the head of the voice department, the opera director and the band conductor. Our violinist has been talking all week about how wonderful the bow makes me sound. I have made the Berg Bow my first bow and put my Tourte in the box."

William Conable

Warren Davidson

Concertmaster, Recitalist, Teacher

"Adding my voice to Csaba Erdelyi's and others: the Berg is not only the best composite bow available, they sound better than any other bow I have tried. At the International Viola Congress , I did some blind taste tests against bows by Emile Ouchard ($15K!), Tubbs, and some contemporary makers. and in every case listeners chose the Berg as making the best sound. The Berg is not something to try if you want a great composite bow - it's what you should try if you are looking for a great bow."

Warren Davidson

Alan de Veritch

Past President, American Viola Society

"Ever since I became aware of the Berg violin and cello bows in the mid-1990's I have been pressuring Michael Duff to produce a viola bow. It has been worth the wait! The new Berg viola bows are just what the doctor ordered. Rarely have I had the good fortune to play a bow that virtually has it all....and this is it. How unique it is to have a stick be warm and sensitive at one moment and powerful and articulate the next. Not to mention it's affordability. I am looking forward to years of camaraderie with my new Berg bow and plan to encourage my students and colleagues to give the Berg bow serious consideration as well."

Alan de Veritch

Adam Gruchot

Concertmaster,
The Kristiansand Symphony Orchestra of Norway

"The gold mounted bow you made for me looks fantastic. All of the praise from your distinguished list of clients is true, so it is hard to add to that!

Its balance is amazing. The sound is big, clear, and I cam make many different colors and nuances with it. When I desire to produce special kinds of articulation it responds immediately and easily. In fact it seems to be ahead of me, anticipating what I desire, so I am much more relaxed playing solos. Also, I found that playing chords, especially in fugues of J. S. Bach, it gives me a wonderful relaxed and secure feeling. I don't have to resort to extra pressure or attack on the chord to get a balanced sound in every voice. I have never had such a feeling with any other bow. This is the best bow I have ever played. Thank you Michael for your masterful work. My wife will order one too!"

Adam Gruchot

Victor de Almeida

Principal Violist,
Cincinnati Symphony Orchestra

"In excerpts ranging from Bach to Bartok, my deluxe Berg viola bow crafted by Michael Duff speaks clearly under incredible pressure and scrutiny. It is resilient and reliable for playing excerpts of every style, every bow stroke, every dynamic – natural and unnatural. It responds clearly and does everything I want it to do. In passionate orchestral solos such as. Ginastera and Kodaly, I am very satisfied with the immense power of the bow that allows me to dig into the string all the way to the tip. It can withstand the abuse of even the most vulgar playing and permits an enormous range of sound: a quality necessary for exaggerating everything for the sake of leading an orchestral section. The bow also allows me to achieve the other extreme of playing incredibly, even unnaturally softly (if only for the sake of demonstrating that capability) without losing clarity: a characteristic that many Pernambuco bows at three times the price wouldn't be able to perform."
