The C411 PP Condenser Microphone from AKG is a miniature vibration pickup microphone with a MPAV standard 3-pin XLR male connector for acoustic guitar, mandolin, violin, and most other string instruments. Its integrated condenser capsule will reproduce the sound of the instrument clearly and without coloration. This microphone can be attached either on or near the bridge with the included non-marking, solvent-free adhesive pad without changing the balance of the instrument. A microphone bag is included for storage and transport.
