The FireBall V, with a cardioid pickup pattern for isolation and feedback control, is equipped with a VLM™ diaphragm for natural sound reproduction with an exceptional transient response. Designed for harmonicas (both diatonic and chromatic) and beatbox, the FireBall V has the added feature of a volume control knob. The Fireball V has a wide frequency response of 50 Hz – 16 kHz and is lightweight, compact, and comfortable to hold.Because the FireBall V is a low impedance microphone, a quality, low-high impedance transformer (T50k is required when using a guitar amplifier). Designed, assembled, and tested by Audix in the USA.
