Topic: Unstable low A natural
Every so often, I will make a reed that in other respects seems excellent, but low A is unstable when attacked with anything louder than mezzoforte: the pitch will start correct then destablize and go flat. Not unlike a reed where E2 will go flat until you cut the tip back. I just finished a blank that is very excellent in all other respects, very responsive and in tune on most other pitches, but when I hit low A hard enough it breaks and goes flat. I have been making my reeds from purchased gouged/shaped/profiled cane for about 12 years now, and only recently and rarely have seen this specific problem. I play a FOX 601. Any ideas out there???
