Since they began in 1962, the Marshall name has been synonymous with high quality distortion tones. Initally, the way to get classic Marshall distortion was to naturally overdrive one of their valve amps by cranking it up to full volume. As time went by their Master Volume heads allowed the generation of more extreme levels of distortion as the pre-amp valves were driven into overdrive. Their first generation pedals simulated these various valve amp type distortions in convenient, cost effective stomp boxes. The Jackhammer is the next step on from previous Marshall distortion pedals.
