Awesome amp I've had for a long time. It holds a charge for quite a while. At least 10 to 20 hours of jam time. You can play your guitar at the same time as singing into your mic. Perfect for busking. Or jamming with friends. You can plug an aux cord to play audio through it. But my old aux cord tip snapped inside. The amp works great, and I can throw in a guitar cable. Comes with charging cable. I can also send more pictures and information through text.
