Voodoo Lab has several options but doesn"t specify eventides.
You can power an Eventide Stompbox, like TimeFactor or
PitchFactor, using a special “current doubling” cable. This is a
parallel Y-cable used to combine both outputs 5 and 6 to double the
available current. Set switches 5 and 6 both away from NORMAL
and use a current doubler adapter (not included) with the red
5.5 x 2.5mm barrel cable.
