When we stopped by the local shop yesterday to check out their tuners, my wife said one of the store reps suggested to her that I “draw a line” on the cork of the MP so that, each time I put my MP on the cork, I would be “in tune”. I’ve never heard of anyone doing that, but I told my wife I don’t think that’s good advice because I don’t think it would be a very reliable way to go about it. Weather can effect our reeds….can’t it also effect the Sax being in tune from day-to-day (if it’s too cold, too hot, etc.) Maybe I’m wrong, but that was just my thought about that kind of advice. It’s been VERY hot and humid here lately…wondering if that has also effected some of my reeds?
