This recently updated amplifier from Roland works well for most instruments and voice. It is light enough that it can easily be carried as a portable PA for walking tours or to amplify your instrument to busk. It now comes with iCube Link, the Roland app that connects to your iPhone or iPad. The Microcube is especially great for guitar players with it's many built in effects and amp sounds to chose from. It comes with the power supply and also works with batteries (not incl).
