Tube distortion
This section emulates the tube distortion.
There are three controls in this section:
•
Tube bias
– This controls the amplitude of the odd harmonics appearing in distorted signal. The greater value
of this knob, the more harmonics in the signal.
•
Tone
– This is a cross fade between the output from the fixed Hi-pass filter and the dry signal after the tube
distortion.
•
Brightness
– Number of harmonics that emerge in the tube. This could also be described as the control which
gives a smooth transition between tube distortion and diode clipping distortion.
