sound while channel two is well-suited when strong distortion is required. The Drive knob is used
to adjust the amount of distortion in the sound. The sound becomes more and more distorted as the
knob is turned clockwise. The
Mid knob is used to set the amount of mid-range frequencies in the
sound. In its middle position, the sound is not modified, mids are cut or boosted by up to ± 12 dB
by turning this knob to the left or right. The Level knob is a gain knob which is used to adjust the
overall volume of the amplifier. Note that the effect of this control on the frequency response of
the amplifier is different for each channel.
The Low and High parameters are used to boost or cut low and high frequencies respectively
by up to pm 18dB by turning the knob from its center position. These controls have a similar
behavior for both channels. Additional control on the frequency response is obtained by using the
Bite control which is switched on or off by clicking on the Bite LED just before to the channel
selector. This parameter boosts high frequencies while cutting some low frequencies for a brighter
sound.
The low-cut (or high-pass) filter is used to remove from the output sound of the instrument
frequency components below the cut-off frequency. The cut-off frequency of the filter is increased
by turning the knob clockwise. when this knob is in its leftmost position, the filter has no effect on
the sound.
The spring reverb is turned on or off by using the spring LED in the top right of the section
labelled Spring . The Mix knob is used to set the amount of wet signal in the mix, turning the knob
clockwise increasing the amount of reverberation in the signal.
Finally, the speaker cabinet is switched on or off by clicking on the LED in the upper right
corner of the cabinet section of the module. This part of the module simulates the effect of both
the speaker and the cabinet on the frequency response of the amplifier module. The back of the
cabinet can be open or closed using the
Type selector. Opening the back of the cabinet allows waves
to travel from the back of the cabinet and interfere with those traveling from the front part of the
cabinet resulting in a more colored sound.
5.4.11 Tremolo
The Tremolo module is used to modulate the amplitude of the sound. The Rate knob is used to
control the speed (frequency) of the modulation while the Depth knob controls its amplitude. The
waveform knob is used to change the shape of the waveform used to modulate the sound. In its
leftmost position, the waveform is a triangular and as the knob is turned clockwise it changes to a
smoothed square wave. The
stereo button is used to switch between stereo and mono mode. When
the button is in its on position, the module is in stereo mode and the output signal from bounce
with a 180 degrees phase difference between the left and right channels. In mono mode (button
switched
off ) the signals in the left and right channels are the same.
