Are you running off a laptop by any chance? If so, try disconnecting the power cord and run from batteries. If the humming stops when you do this, it's our old friend the ground loop. This can be fixed by disconnecting the earth pin on the mains plug (the cheapskate way), or by purchasing a ground loop isolator (the proper way). Hope this helps!
