Here’s what Fender say:
The Acoustic Junior GO amplifier delivers full, natural, best-in-class performance for acoustic-electric guitar and vocals. This powerful, portable system has two channels designed for instrument or microphone use, each with studio-quality effects. Other convenient features include Bluetooth wireless audio streaming and an onboard 90-second looper perfect for solo shows. And its rechargeable battery means that you can unplug it from the wall and take your music anywhere!
