Genz Benz's latest portable head moves one step forward from the competition. It offers the same clean sound that most Class D amps produce, but the 3 Valve preamp and Gain-Volume preamp design allows it to sound like a tube driven head. Amazing! If you always wanted a small and lightweight head but were not convinced because of the somewhat "cold" sound, this one does the "warm" thing perfectly too. If you push the Gain button, it will get into classic tube distortion. Now you can have it all.
