Wireless specifically designed for use with bass.

The Nady U-33B UHF is a wireless mic system optimized for use with bass guitar. It includes the U-33B receiver and bodypack transmitter. The receiver operates on single frequencies in the wide-open, uncluttered UHF 470-510MHz band and features Nady's DigiTRUE Diversity circuitry for maximum range and dropout-free performance. Unique companding circuitry delivers enhanced headroom of an industry best 120dB. A front-panel squelch control allows easy adjustment for clear reception. Bass Boost control allows dialing in the precise boost and presence desired.

The wireless bodypack transmitter features a flexible rubber antenna, a locking jack for the instrument cable, a mute switch for silencing the system with the receiver on, and a battery status LED indicator. The Nady bass mic system operates on 3 AAA alkaline or NiMH batteries.
