A Detailed Description
In this chapter we discuss what each parameter does and how the controls work. While Character has a fixed
number of model types, there are an infinite number of combinations in conjunction with the Drive control.

Figure 6.1: Character Block Diagram
The block diagram above illustrates the overall structure of the processing system provided by Character. This
diagram does not indicate the metering blocks.
Now lets examine the various processing blocks indicated in the diagram.
Drive
The Drive control applies ±24 dB of gain to the signal before it goes to the modeling section. This allows you
attenuate the signal for a subtle effect, or boost to get a more dramatic effect.
As gain is changed before the modeling stage, the inverse gain is applied after. For example, if you set the
Drive control to +6 dB, the gain is boosted 6 dB before the model and cut by 6 dB after. This allows you to
“push” the modeling section with no increase in output level. You may also hit the model with less signal by
setting the Drive control to a negative value without loss of overall volume.
You may still experience in increase in signal level when using positive Drive gain with some models; you
can use the Output Gain control to correct this.
Please note that the Drive parameter may have a greater range than you need for a given model.
Character Model
Each Model represents a digital “copy” of an analog device; some models are made from measuring a device
with different combinations of settings. The most effective way to utilize Character is to listen to how each
model affects your sound rather than relying on the name alone.
• None: No modeling is applied.
• Transformer: Applies the harmonic distortion signature of a transformer-coupled input.
• Valve: A tube-based EQ input stage.
• FET: Model of a solid state (transistor) front end.
• Soft Sat: Tube-based EQ with saturation.
• Boutique Tube: Hand-made tube mic pre.
• American Transformer 1: A variation of the “Transformer” model.
• American Transformer 2: Second variation of the “Transformer” model.
• California Tube Mic: American designed tube mic pre.
