Re: Sax Sound Issues
from a personal dislike of rovner ligatures, I say you should get a different one. Rovners, in my experience, dont actually put pressure on the reed, but the sides of the mouthpiece instead, which is obviously not ideal for holding on the reed. Try a BG ligature. they solve this by having a metal plate in contact with the reed.
I highly doubt its the mouthpiece or the horn(s), It could be reeds warping a bit, fine-grain sandpaper is your friend here. Check for flatness by setting the reed on a piece of glass, or something else reasonably sturdy that you know is machined flat, put one finger on one side of the stock, another finger on the other side, and try to rock the reed back and forth. if it does move, its warped. If its warped, using sandpaper or a file, carefully rub the reed back and forth, checking every so often to make sure you done knock more off the reed than what you need to.
