Gemini GMU-G100 Wireless UHF Guitar System (512 to 541.7 MHz)

$ 49.95

The Gemini GMU-G100 is a wireless UHF guitar system featuring a plug-on transmitter and plug-in receiver, allowing the musician to roam freely without being encumbered by wires at a distance up to 164' away from the receiver.

Each component is powered by a rechargeable lithium battery and uses a standard 1/4" TS plug. Simply plug the transmitter into the guitar's 1/4" jack and the receiver into a 1/4" input on your PA speaker, amp, or mixer. The transmitter and receiver pair automatically upon powering up; if interference is present, simply press the SET button on the transmitter to switch to a new frequency.
