Here's a Shure Commando Model 430 Controlled Magnetic Reluctance microphone from the early 1960's. This microphone has a crunchy sound that has become popular with harmonica players. Aside from harmonica, these make great effects microphones when an old, dirty sound is wanted. I'd recommend this one for effects on vocals, guitars, drums, rooms, or anything else that needs a vintage color added. This one has been wired up for XLR and is ready for use! Grab a dirty effects microphone from the 1960's from Shure!
