Comes as shown It powers on but there is a short in the cord where you see the black tape. If I move it slightly the power light will go off and on. I have no interest in getting shocked so I have not and will not test further so I am selling as parts or repair.

For sale is a vintage Grass Instruments S48 Stimulator. This unit was pulled from a working environment. As shown in the photos, the device **powers on** correctly, and the power indicator light is bright. All knobs and switches are physically intact and move as they should. I do not have an oscilloscope to test the electrical output, so the full functionality and calibration are unknown. What you see in the pictures is what you will receive.
