1st octave low hand is sharp

In my quest for good tuning I’ve been fiddling with my reed and decided to ask the maker for a new one. Turns out, this new one plays almost exactly the same way. The bottom notes on the first octave are sharp. D, E, F #, G, A. With some tape, they come in nicely but it mellows out the low hand considerably. What’s the deal? Is it the reeds, the chanter, or my anal retentiveness? :confused: How about carving?

Who is the maker?The chanter should really go back to the w/s so that a suitable reed can be made for it or the chanter rectified.Do not even think of carving yet :boggle:
