Abstract: A motorized string tuning apparatus is set forth for the tuning of string instruments by the tensioning of the elongated filaments associated therewith. A portable motorized unit with an axially disposed shaft emanating therefrom rotatably engages and tightens the aforenoted string instruments for tuning purposes. Associated therewith are a plurality of illuminating lights for application in dimly lit environments and further including a counter means enabling a user to gauge the rotations of the device avoiding over-tightening of the aforenoted filaments.
