Between its four channels, this combo has the flexibility to handle instruments with piezo transducers or magnetic pick-ups, plus microphones for both vocal and instrument reproduction. Its 2 x 50 Watt stereo configuration gives you enough power to perform on stage with superb clarity, while the provision of a balanced line out allows direct connection to an external PA system for larger concert venues. English The built-in digital effects add an entirely new dimension to the range of sounds available.
