Here’s a pair of Electro Voice N/D 308B & single 408B Dynamic Microphones from the 1990's. The “N/D” series by Electro Voice stood for a change to neodymium magnets (as opposed to alnico), which they claimed had “four times the power potential of conventional microphone magnets”. Today, neodymium magnets are used for most dynamic and ribbon microphone designs, so these marked part of the change from alnico to neodymium. All specs aside, these are nice large diaphragm dynamic microphones that sound great on tom’s, guitar amps, and more. The 308B's are being sold as a pair, and the super-cardioid 408B is being sold as a single. If you’ve been looking for some nice affordable dynamics, these are for you! Grab this pair or single N/D 308B & 408B Dynamic Microphone from Electro Voice!
