I just bought a Boss MT-2 Metal Zone Pedal second hand for like 2800Rs. I couldn't test it in the store, they didn;t have the cables. My guitar is in my room near college, i;ll be going there today afternoon. I just hope to God it works. I tried connecting an adaptor and the check light didn't light, and when i tried a 9V battery i didn;t light as well, but i think the battery is almost dead. This is my first pedal. Please guys just temme that the check light will only light when the input and output of the pedal are connected. I know this is a metal effects pedal, but what kind of equalizer setting should i set it to play rock, like bryan adams (SUmmer of 69). Anyone who owns this please help me out, and how does the polarity of the adaptor go, the inscription is faded on this pedal, the negative is inside rite? Can i use a normal variable adaptor on this? PLease help me out, asap.
