Apart from other features, this is what drove me to it
Unleash your inner pop star
Keep everyone entertained – with two microphone inputs, you and your guests can go head-to-head singing along to your favourite tunes. Alternatively, add a rock and roll layer by connecting a guitar to one of the inputs and using the system as a guitar amp. Enjoy three modes: Clean for a clear sound, Overdrive for a distorted guitar sound, and Bass for your bass guitar. And when you’re finished, the unit has two microphone holders, so you can store your mics safely.
