Vox AmPlug2 AP2-BS Bass Headphone Amplifer

With amPlug 2, the crucial analog circuit has been drastically improved, and each model now provides three modes. Guitar types provide multi-effect functionality, and a rhythm function has been added to the bass type. A foldable plug mechanism that rotates 180 degrees and an auto power-off function are additional features that contribute significantly to improved convenience and ease of use.
The amPlug is the simplest way to get serious sound; occupying virtually no space, it's an ideal choice for any guitarist or bassist.
