The Distortion effect simulates an overdriven two-stage tube amplifier. Its primary role is to simulate the Leslie amplifier or another amplifier used to feed the Leslie speaker cabinet.
Distortion On/Off switch: Turn on or bypass the Distortion effect.
Type pop-up menu: Choose a tube amplifier model.
Growl: Simulates a two-stage tube amplifier. It closely resembles the Leslie 122 model, the classic partner for the Hammond B3 organ.
Bity: Reminiscent of a bluesy guitar amp.
Nasty: Delivers hard distortions and is suitable for very aggressive sounds.
6550 AB V3: Tube distortion sound modeled on class AB amp head.
6550 AB V2: Tube distortion sound modeled on class AB amp head.
6550 GL: Tube distortion sound modeled on tube amp head.
Tone knob and field: Change the distorted portion of the sound. This has no effect on the dry signal portion. Limiting changes to the distorted signal allows for very warm overdriven sounds that do not become scratchy if you try to get more treble out of Vintage B3.
Drive knob and field: Set the amount of overdrive distortion. The output level is automatically compensated for, so there’s no need for a distortion output volume control. A level of 0 effectively turns off the Distortion circuit.
Note: The Drive knob shown in the Main window is linked with the Drive knob shown in the Effects window. When you rotate either Drive knob, your change is mirrored in the other window. In essence, this is a convenience feature that addresses the same parameter in both locations.
