Rocktron Zombie Rectified Distortion - Manual (Page 11)

3. Turn the ZOMBIE on and adjust your BASS and TREBLE to get you close to
the desired sound.
4. Now slowly turn the STARE control and notice the change.
5. You may want to adjust the BASS and TREBLE to compensate for this change.
NOTE: STARE CONTROL: The STARE Control has a very pronounced and
noticeable effect on the perception of the distortion. A little goes a long way. This
control actually changes the symmetry of the wave form..... A guitar produces sine
waves. A SINE WAVE is like a circle that has been cut in half with one half going
up and the other half going down. The half going up is know as the positive
excursion and the half going down is called the negative excursion. The STARE
Control allows the negative portion of the wave form to become larger than the
positive portion. This creates more harmonics to be produced as it drives
the tube. If you turn the STARE Control full counter clockwise the distortion will
be symmetrical. Both positive and negative portions are equal size. As you turn
the STARE control clockwise the negative portion will begin to increase in
size, this causes the negative portion to begin distorting before positive portion
thus creating asymmetrical distortion.... This is what gives the auditory impression
of a more in your face sound emanating from your cabinet.
Please experiment and have fun raising the dead with the ZOMBIE......
