Installation Instructions 

  • The ideal placement for attaching the TSE differs with each instrument.  
  • Based on our tests, mounting the TSE between the 1st and 2nd valve is recommended. 
  • The instruction provided on the packaging is only a suggested method for attaching this product to the instrument 
  • Due to the large variety of instruments, we're not able to offer a specific recommendation. 
  • The results of the TSE vary depending on the instrument and its positioning. 
  • Some customers have indicated their use of two TSE units. 


We hope you'll discover the ideal position for the TSE with our instructions and the joy of making music.
