The FireBall™ dynamic instrument microphone is designed for harmonicas (both diatonic and chromatic) and beatbox. Clear, accurate, and capable of handling SPLs in excess of 140 dB without distortion, the FireBall™ is ideally suited for both live stage and studio recording applications. The FireBall™ microphone has a smooth, uniform frequency response of 50 Hz – 16 kHz, and a cardioid pickup pattern for isolation and feedback control. It is lightweight, compact, and comfortable to hold. The FireBall™ is manufactured with a precision machined aluminum body, steel mesh grille, and a unique three-stage marbled anodized finish. Because the FireBall™ cardioid instrument microphone is a low impedance microphone, when using with a guitar amplifier, a quality, low-high impedance transformer (see T50k) is required. Designed, machined, assembled, and tested by Audix in the USA.
