MIC MORSEL: THE VANISHING BUFFALO
In this case, the "BUFFALO" is the full-sized Rochelle salt piezo-electric crystal element.
I bet you're relieved that you won't be trying to 'cup' a Bison -altho that would be a great photo-op... What I'm referring to is the dwindling number of full-sized crystal elements in the realms of Lord Microphone. I'm seeing a greater proportion of players opting to replace failing crystals (MC-151's and R7's) with more dependable elements. Yes, stability offers advantages, but be aware that the significant differences in impedance between these various units should be considered and adjusted for.
More (more than a morsel) to come...
