I have two KSM32 microphones, manufactured several years apart. The grill screens are different. Is this correct?
The KSM32 grille has changed since it's introduction. Around 2002, Shure shifted to a more "coarse" grille (but not as "coarse" as the KSM27) to "visually differentiate" the KSM32 from a KSM44. There are no sonic differences; the change is purely cosmetic.
