I have become curious about claims for freezing my reeds to double the
life. Anyone with personal experience?
Cryogenic Process:
CRR, or cryogenic resonance restoration, is the gradual lowering (1 degree
per minute to -325 degrees)and raising of the temperature of the
instrument. Theoretically, it relieves stress and tension in the metal and
improves the instrument's response and resonance. (Claims to reduce stress
fractures, the main reason for reed breakage.)
"This is a controversial method and the jury is still out as to whether it
actually makes a difference. It has yet to be proven in blind listening
tests." http://www.musicservices.co.nz/brass_temper
