The concept behind Marshalls’ revolutionary Valvestate™ technology was to emulate the performance of a Marshall valve power stage without actually using power valves. By providing the warmth, feel, responsiveness and sheer musicality of a valve amp without involving the cost and weight, Valvestate™ has placed this classic valve- like sound in the hands of thousands of musicians the world over.
By harnessing the technology used in Valvestate and adapting it for use with bass guitar we have created Bass- State™ - a revolutionary new concept in bass amplification.
