The FireBall 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 mic 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 grill and unique three stage marbled anodized finish.Because the FireBall is a low impedance microphone, when using with a guitar amplifier, a quality, low-high impedance transformer (see T50k) is required.
