NotesFor more than 50 years, the Marshall name has been synonymous with genre defining distortion tones. Initially, the way to get classic Marshall distortion was to naturally overdrive one of our valve amps by cranking it up to full volume. As time went by, Marshall Master Volume heads allowed for even more extreme levels of distortion, as the preamp valves were driven harder. The first generation of Marshall pedals simulated the various types of valve distortions in convenient, cost-effective stomp boxes. The Jackhammer is the next evolutionary step in Marshall distortion pedals. The JH-1 contains our most outrageous distortion levels to date. The Contour control allows you to not only scoop out the mids, but also choose the frequencies at which the scoop occurs, allowing you to tailor your sound to your individual requirements. Although the Jackhammer has more aggression and gain than any other Marshall pedal, we never forget our heritage, with the JH-1 producing natural and realistic tones.
