<div class="">Honestly, I can’t think of any. If everything else fails, you can still use a motorised pot, as someone else already wrote. Even if the control is not done by a potentiometer (say, a moveable record or playback head in a tape echo), you could
still use some sort of mechanical servo.</div>
