New sweep, Up-down stair step.

 Something like linear sweep, using a triangle wave, except the voltage raises and falls in steps. The effect is similar to a hack box, except the sweep does not reset and start at the beginning of the band.

 The following voice is from  Step/Linear sweep box #1.
 
 "native spirits"
 
 You can hear the thumping that is from the steps.
