Cgs synth

Basically the grinder is exploiting exactly what you DON'T want in a typical
servo system (such as the feedback of an op-amp. It causes the op-amp to
overcompensate, then overcompensate in the reverse direction etc,
effectively causing a high pitch ringing on the output wave. If you have an
oscilliscope, it can help choosing a chip.
