Chapter 3 Distortion eects 79
Distortion II
Distortion II emulates the distortion circuit of a Hammond B3 organ. You can use it on musical
instruments to recreate this classic eect or can use it creatively when designing new sounds.
Distortion II parameters
•
PreGain knob: Rotate to set the amount of gain applied to the input signal.
•
Drive knob: Rotate to set the amount of saturation applied to the signal.
•
Tone knob: Rotate to set the frequency of the highpass lter. Filtering the harmonically rich
distorted signal produces a softer tone.
•
Type pop-up menu: Choose the type of distortion.
•
Growl: Emulates a two-stage tube amplier similar to the type found in a Leslie 122 speaker
cabinet, which is often used with the Hammond B3 organ.
•
Bity: Emulates the sound of a bluesy (overdriven) guitar amp.
•
Nasty: Produces hard distortion, suitable for creating very aggressive sounds.
Overdrive
Overdrive emulates the distortion produced by a eld eect transistor (FET), commonly used
in solid-state musical instrument ampliers and hardware eects devices. When saturated, FETs
generate a warmer-sounding distortion than bipolar transistors, such as those emulated by the
Distortion eect.
Overdrive parameters
•
Drive slider and eld: Drag to set the saturation amount for the simulated transistor.
•
Display: Shows the impact of parameters on the signal.
•
Tone knob and eld: Rotate to set the frequency for the high cut lter. Filtering the harmonically
rich distorted signal produces a softer tone.
•
Output slider and eld: Drag to set the output level. This enables you to compensate for
increases in loudness caused by using Overdrive.
