GRBass comes from the mind of the Italian musician and engineer Gianfranco Rizzi. His amp heads, cabinets and combos were all desgined with one philosophy in mind: pure sound. This new and exciting line will be hard to resist for the modern bass player that looks for compact yet powerfull amplification that respects the pure sound of his instrument.
