I just bought a Boss Metal zone MT-2 and set it up to how it said on the boss site to get the right heavy metal sound i want, but when i turn the pedal on the buzzing in the back ground is really loud! :'( when i turn the level up half way the buzzing in the back ground just takes the piss, it actauly overpowers the guitar. How can i stop the buzzing without loosing the effect? Do i have to set my amp's equalizer up to go with the pedal or anything?

Please help me, Jowin
