I just happened to find an old pair of Sennheiser ME40 short shotgun microphones with K6 power supply system. Both of the capsules have their metal grilles missing. Any idea how it affects the sound and are there any replacement grilles available somewhere? Haven't tried them yet. I guess they should work okay for overheads.
P.S. Got home and tried them. The other seems to work fine and the other was dead. One wire was cut, I soldered it and it works now fine, too. Any idea about the grille?
