Marshall JH1 Jackhammer

 This metallic monster boasts two modes (Crunch n Lead), each of which is loaded with ungodly gain plus all the tonal control you need to push your guitars sound straight over the edge. From cranium crushing crunch and scooped, modern metal mayhem to savage, slamming solos, the JH-1 is the most extreme distortion pedal on the planet.
If you want the earth to move - you need a Jackhammer! HM Government Warning: Use of this pedal will add unsurpassed brutality to your tone. Definitely not for the faint of heart
