Topic: flat G on PV series non-AK Loree
My wife is struggling with a flat G on what is otherwise a superb new Loree. She had this problem on a previous LF AK series, which we took to Paul Covey who did some tone hole work and fixed the problem nicely. When I removed the F# key though to look at the G tone hole, on that LF series, I could see that he undercut the tone hole on the bottom (toward the bell) side. It worked, but to me is counterintuitive. If a note is flat, wouldn't you want to undercut it's tone hole on the upper side, effectively moving the hole slightly up the tube? Can someone help me understand why Paul's technique worked?
