Even in the past, professionals were enthusiastic about Kühnl & Hoyer instruments!
Excerpt from the letter from Horst Fischer to Kühnl & Hoyer in 1982:
In my 30 years as a soloist in the most famous big bands at German radio stations, I blew all the trumpets that existed on the world market. This instrument from Kühnl meets all my expectations. Good response up to top C, light in weight and very good workmanship. I wish all trumpeters who play this wonderful instrument a lot of joy and success.
Sincerely yours, Horst Fischer
