About us

Who we are

Tenor Madness is a professional woodwind repair shop that specializes in top end vintage and modern professional model saxophones. With almost 75 years of combined experience, Randy and Shirley Jones, Thomas Helmer, and the rest of the TM team have put Tenor Madness on the map as one of the premiere saxophone repair shops in the country.

For the past 21 years, 90% of the repair work at the shop has been performed on vintage and professional model Conn and Selmer saxophones. This experience has provided Tenor Madness with unique insights on saxophone repair and setup. Tenor Madness is driven by a shared passion for bringing out the very best in every instrument that comes into its shop. Every last detail of each instrument is painstakingly addressed in a patient and thorough fashion.

Tenor Madness is located in Waterloo, Iowa.
