  ------------------my response------------------
I certainly may be wrong, but in my experience, getting a hum and or
picking up the radio is a sign of an open ground or lack of grounded
shielding in a mic cable.  The effects box probably has a shielded ground
and is handling things.  Check all of your cable connections at both ends
and make sure you have no broken connections.
