Can someone suggest a metal ligature that will fit a LAW Buzzer? The one I'm using (a two-screw generic) is 'goofy', and the screws end up tweaked at a slight angle. It holds the reed in place, but it's only a matter of time before the threads wear out. I'd like something with one screw (FL, BG, Optimum), but I'm not sure which will fit. Anyone here play a Buzzer and use a metal lig with it?
