JH 1 Jackhammer

Flexible overdrive/distortion pedal from Marshall

The Marshall JH-1 JACKHAMMER Guitar Effect Pedal, Ultragain Overdrive. Create your own truely awesome, extreme Marshall distortion tones.

The Marshall JH-1 JACKHAMMER delivers the extreme distortion effects you crave. Since Marshall began in 1962, the Marshall name has been synonymous with high quality distortion tones. Initially, 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 the Marshall Master Volume heads allowed the generation of more extreme levels of distortion as the pre-amp valves were driven into overdrive. Marshall's 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. The JH1 pedal contains Marshall's most extreme distortion levels to date, combined with a Contour section that allows you to not only scoop out the mids, but also choose the frequencies at which the scoop occurs. This means that you can tailor your sound to your own individual requirements. Although the Jackhammer has more aggression and gain than any other Marshall pedal, thay never forget their heritage. The sounds contained are always natural and realistic, like a super high-gain valve head pushed to the max.
