For musicians who want more precision in their strength, we offer sub-measures (Light, Medium, Strong). The Strong being harder than the Medium, and the Medium being harder than the Light. It’s not a difference in tone.
A musician who plays the number 3 and who likes only the strong reeds will be able to choose a box of strength reeds 3 Strong. Thus, all the reeds of his box will suit him and he will have less losses. All the reeds in his box will have the same strength.
