The buzzing noise could be caused by a grould feedback loop. This occures when the amp is plugged into one power socket and the guitar's amp is plugged into a drifferent power socket.
Try to use a power board, plug in all your devices into this power board and plug the power board into a power socket.

MAKE sure you have it connected to a three wire circuit that has the ground. A lot of these style amps will buzz if they are left ungrounded.
Also search for sources of buzzing light light dimmers.
Further, power supply electrolytic filter caps are suspect.

SOURCE: Buzzes and feedback
Make sure the "ground lift" option is used on the direct box.
DO NOT UNDER ANY CIRCUMSTANCES use a headphone output jack as the output of this unit. The headphone jack is for HEADPHONES that have no return to ground. Use of this as drive to a sound board is sure to cause problems and in some cases can fry these amps due to the circuitry.
The cable used to go to the direct box should be very short and high quality.
You should source the power for this unit from the SAME source and receptacle as your sound board if at all possible.

This sounds like a broken ground wire or trace within the unit if an IDENTICAL pedal does not act the same AT THE SAME SETTINGS.
Sometimes a circuit trace gets broken on the board inside pedals and can cause this.
Since an identical pedal doesn't have the problem, service is required.
If you know electronics you can open the pedal and look for obvious problems.
HINT: Use a bright LED penlight to "candle" the circuit board to look for cracks.
Look for broken solder joints... this can take an experienced eye to spot.
A distortion pedal NORMALLY is very simple circuitry.
