A great vintage microphone can define a record. A poor one can become an expensive ornament. Here's what to look at before you buy.
The capsule is the heart
Most of a condenser microphone's character lives in the capsule. Ask whether it is original, whether it has been re-skinned or replaced, and by whom. A professionally serviced capsule isn't a problem — an unknown history can be.
Valves and power supplies
Valve microphones depend on the right tube and a healthy power supply. Check that the supply is the correct type for the microphone, that the cable is present and in good condition, and whether the valve is original, a matched replacement or a modern substitute.
Noise, hum and consistency
- Listen for excessive self-noise, crackle or hum.
- Check each polar pattern if the microphone has more than one.
- Gently tap the body and listen for intermittent faults.
Cosmetics versus function
Scuffed paint and worn badges are part of a working microphone's story and rarely affect the sound. Dents to the head basket or evidence of moisture inside are different — ask directly.
Ask for a recording. A short sample of the microphone on a voice tells you more than a photo ever will.
Paperwork and provenance
Serial numbers, service receipts and previous studio history all add confidence — and value. Where provenance is known, a reputable seller will share it.
