The Cool Note process has been hailed as the greatest advancement for brass instruments in the last 50 years. By treating the instrument at sub-zero temperatures, inherent stresses within the structure of the brass called "residual stresses" are released. Brass instruments respond to this gentle process providing increased tonal quality, volume, and lower or higher register.

By treating the instrument at sub-zero temperatures, inherent stresses within the structure of the brass called "residual stresses" are released. This allows your instrument to play and sound the way it was designed to perform. Here's what professional musicians have to say about "Cool Note"..

"The richness of overtones made my trumpet seem larger than ever. Another improvement was the absence of "flat spots" over the range of the horn at all dynamic levels. A side benefit of the easier response was that I felt less fatigued after a show. My newly cryo'ed horn and mouthpiece is now capable of whispering like a kitten or barking like a big dog!" Mark Curry - 24 kt Gold Plated Shilke S-32 Trumpet Performer Flamingo HIlton in Reno, Nevada Owner-Sound Sleeve Performance Products

"A rounder more pleasant-resonant tone and the process mellowed by Bb and C. I liked the overall sensation of the trumpet and I wasn't as tired at the end of rehearsal. Several people complemented me on my sound, especially the conductor! The valves feel even better and smoother than before. The double high G finally is focused on my Bb, before it didn't seem to exist. Now I can play both my Bb and C trumpet without heavy caps, or tape to try to deaden it, yet it feels very resonant in my hand and to my ear." Ken Anistrum-Trumpet Principal Trumpet "New Philharmonic" Chicago, Il

"We noticed the horns treated had a darker and rounder sound. The process expanded the registers (high, medium, and low), and made the horns freer blowing, along with improved pitch centering" Scot Stewart - Director Madison Scouts, Madison Wi
