No, like you stated, I rarely take the reed of my mp. just when I get a new box or 2 I chuck em all in the glass of water and go thru them.
Dazza, you should experiment with this since you have had some interestingly good results… find out why. Do a 5-10 minute soak, 12 hour soak etc to see if there are any differences. I’m by no means suggesting my way of just leaving the reed on is good, and would rather recommend no one do that. I’m lazy that way and the reed really does pop back after a minute of playing so it works for me but there are better ways!
