A transmitter plugs into the instrument like the end of a cord, and a receiver plugs into the pedal board or amplifier like the other end of the cord.

Advantages*no cost to buy regular or rechargeable batteries*extremely simple operation*no need to set up a bulky wireless receiver on your amp/pedal board

I carry it with me like a virtual cable because it has no bulky receiver they needs to be plugged in

However, the receiver that I received does not hold charge - after a full charge it would drain out without any usage after a day

The receiver is completely dead and will not hold a charge

There is no body pack transmitter to fumble with and no bulky receiver to plug in and mount on top of your amp or pedal board and plug in an ac adapter to power it

My receiver seems to burn its battery faster than the transmitter

But then again, you have to carry a bulky receiver with you, plug it into a power outlet and into the amp

Easy to use, compact, no need for AC power supply or bulky transmitter or receiver

Instead of all these elaborate and complex wireless body packs and space consuming and complex receiver boxes, this system is so simple, I cannot believe it.
