The 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, we never forget our heritage. The sounds contained are always natural and realistic, like a super high-gain valve head pushed to the max.
