It's ready to play! And it has a useful MUTE function; just short click the transmitter's POWER button when you want to stop playing for a short time.

Stay Charged, Stay Tuned!

There's also an optional Cable Tone simulation to get your tone with the cable capacitive effect without using a cord. Cable Tone simulation makes your sound as natural as using a high-quality cable. Press the receiver's power button (short click) to activate the Cable Tone, the LED indicator will change to ORANGE color.

This is a very helpful item.I have never used this type of system because I was afraid that it will fail during the show and/or the gig and make a fool of myself on stage. but I have it as a gift and I had to use it and the truth is, I was surprised because it lasted all night and it didn't turn off and/or it stopped working. With all the confidence I can recommend it to any guitarist without fear of making a fool them selfs on stage.I am very happy with it and every gig I use it, I thanks the good friend who gave it to me.
