Hi Tatelev,
If you hang on a bit, and look at your previous post asking about reed positions, John Broecker is going to post a diagram of the reed layout for that harmonica. I suggest that, whenever you decide to do some tuning, make a copy of the diagram for your records. You can play each note and determine whether it's out of tune, and by how much. Then you can use that diagram to work through each reed that needs tuning to either bring it up or down to your desired tuning. I've found if I don't keep some type of record as I go, I have no idea what I've done! But ... that happens to me a lot lately, and on many subjects!
