I got this so I could play my acoustic guitar with some effects pedals. It doubles as a speaker for my PC. That lets me use it to amplify my midi software instruments too, and I can do both at the same time. For reasons I cannot fathom, the Bluetooth function is useless to me, because the playback (i.e., from phone) is intermittent. But I can amplify wired input from PC and input from instrument at the same time, and like I said, I love the sound, nice and punchy. The thing looks good too, I chose it in part because it doesn't look like a speaker. Unfortunately I have to ding the workmanship on the fact that the pin fell out of one of the hinges right out of the box, and I snoozed on returning the unit to Thomann to have this fixed. The problem doesn't affect function except for opening and closing the lid, which I have to do gingerly. Also, the controls inside the lid are not firmly secured to the frame, so when you press a plug into it, it gives under the pressure. Just add a screw to make this thing solid, for crying out loud.
