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.
