The Manley Reference Silver Microphone offers a mechanical selector on the rear of the head basket that is switchable between cardioid and omni pick-up patterns. Boasting a mic grade 5670 vacuum tube, Manley IRON® transformers, and a low-noise switch mode power supply, the Manley Reference Silver Microphone is a studio workhorse. 
This microphone is at home in-front of instruments that range from female vocalists, to saxophones, from drum overheads to banjos. Use the Manley Reference Silver Microphone where you might be thinking about a ribbon, and use it with confidence!
