    I bought a 9V 800mA Power Adaptor from RadioShack for my Electro Harmonix Big Muff pedal and I plug it up and it fits fine and everything but it doesnt give any power to the pedal at all. what could be the problem?
     
  2. Check the jack polarity, most pedals are - negative centre pin and + positive outer. Look on your pedal or in the manual normally will say what it should be.I bet thats your problem,

    If you can solder then after unplugging the whole unit you could re-solder it to be correct polarity at the jack plug.
