?With this top quality guitar wireless transmitter receiver system， you can walk anywhere without a long cable and have fun with audience.

Features:
This is a guitar wireless transmitter receiver system， for walking freely when performing.
The longest distance in open reaches about 60m / 200ft， and the ideal distance in open is about 40m / 130ft.
Using UHF 600-870 MHz band and the latest high frequency filter of the RF to avert frequency interference.
PLL system， preset 16 non-interfered channels.
Automatic frequency scan feature searches for available frequencies.
Special design commanding circuit， strongly improve S/N ratio.
Using surface amount technology for PCB， more stable function.
Twice mixer high frequency circuit design， very strong sensitivity.
The?receiver can powered by DC 9V or 3V AA batteries.
One plastic foam-padded box for protecting and carrying convenience.
