Hi Dayo007,
as far as I can see, the Bluetooth unit of all Amplifi models is only receiving audio (from your iPad), not sending it. That means, you can send playback jam tracks from the iPad to the TT while editing sounds at the same time via Bluetooth. But to get the sound (both guitar and jam tracks) you hear on your headphone over your hifi system, you will need to connect a cable (or two if you want to have stereo).
