Here's a 1970's Altec 626A Electret Condenser Microphone in NOS condition! This microphone has a nice smooth sound that unlike some other Electret condenser microphones doesn't get too bright. This microphone runs off of a battery - I'm including a supply of batteries for this microphone that should last a lifetime. I'd recommend this microphone on acoustics and even vocals! These don't come around too often, especially in NOS condition. Grab this lesser known vintage condenser microphone from Altec!
