The outfit of the perfect restored instruments is unique too…But the highest riches of this professional piano-builder is living in his head and heart.

The Glimmer of enthusiasm comes over to his customers, they feel immediately the origin musical genius…Generally he is not only a specially marvellous expert in his line of business, he is the top of all. I would wish, he restored pianos would be declared as a “protected national inheritance”, defending this all over the world important culture inheritance for the next generations.”

Robert Goldberg, Israeli concert Pianist

Purpose: to endorse and recommend Jens-Uwe Witter as an outstanding piano rebuilder, technician, and tuner. My relationship to Herr Witter: I have known Jens-Uwe Witter for nearly two years, during which time I have found him to be highly competent, extremely motivated, and a friend destined for success in the United States. His drive to improve and expand a once small business in Bavaria has rewarded him with a large and impressive rebuilding shop and display studio, which must include at least two hundred pianos of all ages. He possesses an intense commitment to quality workmanship, and an ear for listening to the needs and wants of his customers. I have been in his shop many times, and him in my house, and I recommend his services without reservation. My qualifications and interests: I have played classical concert-level piano and cello for 18 years. I own three pianos (two concert grands, one upright) of two brand names. Jens has worked on one of my grand pianos in Germany, and I was impressed and very pleased with his results. A recreational musician now, I am a Captain in the U.S. Army, currently serving as an Attack Helicopter (AH-64) Pilot and Company Commander. Jens has an intense drive to generate a successful business in the United States. I write this letter for him because I truly believe his workmanship to be outstanding, and I find dealing with him to be nothing less than a pleasure.

Robert Willis, Captain in the U.S. Army, Pilot and Company Commander

“... is diligently renovating old pianos ... Jens-Uwe Witter’s world is the music ... Enough work for the music enthusiast whose hobby ... is also his profession ... Mechanical precision work is as important as the sensitive tuning of pianos. The necessary tools are delicate brain surgical instruments, hammer, crowbar and the biggest open-ended spanner. The smallest screw the piano builder is dealing with is one and a half millimetres, the biggest one is 20 centimetres."

News paper, Franken-Umschau, 29.09.1995



For some years now I watched the activities of the handicraft enterprise "Witter’s Piano Service". Mr. Witter established himself as successful craftsman and is well-known as demanded piano technician and tuner. I am convinced of his reliability and of the quality of his work. For many years now Mr. Witter has been tuning and regulating my grand piano to my greatest satisfaction. Even more positive is that the abilities already mentioned are combined with a special interest and a friendly and warm personality turning to other people with attention and interest. Due to my experiences I may recommend Mr. Witter with pleasure."
