When it comes to compact bass amplifiers, the Roland Cube-30 Bass is in a class all its own. This powerful and lightweight amp combines a 30-watt/10-inch speaker with DSP modeling to crank out a range of popular bass amp sounds. There’s also onboard compression, 3-band EQ and digital effects—making the Cube-30 Bass an incredible value. This is a used amp in excellent condition. Would be perfect for Bass or Keyboards.
