5.4 The Effects Section 53
The Pan knob is used to balance the input signal between the left and right channels. In its
leftmost position, signal will only be fed into the left delay line and one will hear clearly defined
echo first from the left channel and then from the right channel and so on. In its rightmost position,
the behavior will be similar but with the first echo coming from the right channel. These two
extreme position correspond to the standard ping pong effect but a a less extreme behavior can be
obtained by choosing an intermediate position. In particular when the Pan knob is in its center
position, an equal amount of signal is sent in both channels.
The output signal from the Delay module can include a mix of input signal (dry) and delayed
signal (wet). The Wet and Dry knobs are used to adjust the amplitude of each component in the
final output. The amplitude of each component is increased by turning the corresponding knob
clockwise from no signal to an amplitude of +6dB.
5.4.4 Distortion
The Multi-Effect module includes three different types of distortion which are selected using the
Shape selector knob. The Warm Tube effect applies a smooth symmetrical wave shaping to the
input signal resulting in the introduction of odd harmonics in the signal. The Metal distortion is
similar to the Warm Tube effect but is slightly asymmetrical resulting in the introduction of even
and odd harmonics in the signal. The Solid State distortion applies an aggressive symmetrical
clipping to the signal thereby adding high frequency harmonics and resulting in a harsh sound.
The Drive control is a gain knob acting on the input signal. This parameter allows one to adjust
the amount of distortion introduced in the signal by controlling how rapidly the signal reaches
the non-linear portion of the distortion curve applied on the signal. In its leftmost position, the
amplitude of the input signal is reduced by -6 dB; turning this knob clockwise allows one to increase
its amplitude.
The Tone knob is used to adjust the color of the signal after the distortion algorithm has been
applied. In its leftmost position, high frequencies will be attenuated in the signal while in its
rightmost position low frequencies will be filtered out from the signal. In its center position, the
signal will be left unchanged.
The Volume knob is a gain knob acting on the amplitude of the distorted signal. Finally, the Mix
knob allows one to control the amount of dry and wet (distorted) signal in the final output signal
from the Distortion module. In its leftmost position, there is only dry signal in the output while
in its rightmost position one only hears the distorted signal. In its center position, there is an equal
amount of dry and wet signal in the output.
