"The Mini-Bullet Edge VC is one of the best mics I have ever played - it has the Husky Black Thunder high impedance element which sounds just great" (Bertram Becher, Harmonica player, specialist and product manager at Seydel)
Still in lockdown repairing this very rare American D22 dynamic microphone. This mic has dual impedance. Behind the tag is a secret connector. Here you can switch from Low to High Impedance. The mic had some connection problems. I replaced all the wiring and set it up for Low Impedance because the owner uses it to connect directly into a PA for recordings.
