Dynamic instrument microphone designed for high-volume sources, the FM1 provides precise close-miking of guitar cabinets and drums in live and studio contexts. It uses a supercardioid pickup pattern for strong off-axis rejection and a flat 50 Hz–15 kHz response, handling up to 130 dB SPL without distortion. The 300 Ω balanced, low-impedance output and compact side-address form factor support close-in placement, with a mic clip included for secure mounting. Its rugged build and compact size enable reliable use in both stage and studio environments.
