I was using my LowDown Studio in rehearsal the other day, as I have regularly for the past three years, and when I unplugged the power cord from the wall the third prong came right out.  The cable still functions without the ground prong, but I'd like to get a replacement power cable.  This should be easy enough given that it's totally removeable from the body of the amp, but I can't locate this part in the store.  Please let me know how I can acquire an intact power cable so I don't get struck by lightning and die.

Cheers,

Sam
