I picked up my ibanez rg-170 today and plugged it into my laney tubefusion. The problem im having is that the guitar makes a loud humming noise and you can faintly hear the guitar when playing it. I know its not a problem with the amp because my LTD MC-500 works fine with it. Does anybody know what could possibly be wrong and advise me on how to fix it?

Thanks, Andy.
make sure all the wires are connected, and your grounds are all grounded, thats usually the culprit
