A three-position dial was turned either all the way to the right for stutter, to the central position for echo, or to the left for warble. During playback, the trigger had to be held down to activate the stutter, held down for a certain length of the recording then released to enable the echo or held down to activate the warble effect. Hitting play mid-way through the echo effect could delete the remainder of the recording. Yak Bak Power Penz The Yak Bak Power Pens combined working ink pens with the Yak Bak toy.
