The Marshall JH-1 Jackhammer is a downright gnarly distortion pedal aimed at players looking for crushing high-gain metal tones. With an absurd amount of gain on tap and a sweepable Contour control for scooping and shaping the midrange, the JH-1 gets into Master Volume Marshall amp distortion territory and then takes it a couple steps further. But the Jackhammer's no one trick pony. Flip the Mode switch over to "OD" for dynamic overdrive and crunch sounds that most high-gain dirt boxes can't touch. Dual-concentric pots allow for a total of seven controls on this compact, sturdy pedal, saving precious space on your board.

    Much bigger than I though it was going to be, used primarily the OD part of the pedal and played it at my worship service twice. Sounds stupid good and interacts really well with my Blues Driver. I initially wanted a Friedman Brown Eye, but Alas, I have three kids and a wife I must keep happy and…

    As mentioned several times in numerous forums and reviews online, I felt the OD was better than the distortion. For switching from a clean to a distorted tone, though, that might mean clicking 2 buttons (OD channel on the amp with OD on the pedal), instead of just switching to the distortion on the …
