Hello my name is John. I restore, recondition vintage microphones for display, prop and functional use. This microphone has strong output and is in above average cosmetic condition. The 548 series is getting harder to find these days.The microphone has the typical wear from age and use on the chrome body and upper capsule. I replaced the old broken down foam on the capsule and in the screen. " John's vintage microphone gallery".
