I have a seltction of old Ribbons. BM5 BM6 BM7 + BM4, and I use them, professionally, every weekend at a venue in Viborg where I work as a sound-engineer. I have the luxury of being able to confiugre 3 x mono or 2 x mono + 1 stereo. Visiting soundengineers are generously offered the use of them, and I haven't yes met one who didn't end up being soooooo envious. Nothing produces that sound when put in front of a guitarcabinet or suspended over a drumkit. To protect them from any damage, I've inserted a D-powerplud from renowned mic-manufacturer Røde. It boosts 20 dB and filters out phantompower. Two more pictures will follow.
