Smart bluetooth for acoustic/electric guitars

A Bluetooth transmitting device that you connect to the mono jack of your guitar, that then transmits to a bluetooth receiving device (that can be independent or the Bluetooth receiver in your phone or tablet). In this way you can play your guitar with no wires and you can listen to your headphones (or connect a Bluetooth speaker) and in this way hear your guitar is amplified, so that you can record yourself on your device or perform live with no cables to worry about. The signal should be stable and be able to transmit for longer distances, hence smart bluetooth.
