Editing the Guitar Amp and Compression Settings
Black Box provides 40 highly accurate and dynamic guitar amp models based on the most popular classic and modern amps in
existence. We even throw in four bass amps, a few custom amp designs of our own, a fuzz tone and octave fuzz, plus a clean mic
preamplifier. This represents a tremendous library of cherished guitar tones from which to choose, and will definitely allow you to
find the sound you need for your songs.
Black Box also provides an audio compressor. This is useful either as a note sustainer or as a limiter, reducing the level of loud notes
and increasing the level of soft notes. It is placed in the signal chain just before the amp modeling.
To access the amp model and compressor settings, press the Amp key. The lower part of the screen will display the following four
control parameters: AMP, DRIVE, AMP BASS and AMP TREBLE. Here is a description of those four settings plus a couple of others:
Amp
This knob (#1) is used to select one of 40 guitar amplifier models.
Amp Drive
This knob (#2) changes the Amp Drive (0-99), which affects the amount of distortion in the signal. On most amp models, a setting
of 0 is a clean sound and higher settings give increasing levels of distortion or overdrive. The amount of overdrive depends on the
amp selected.
Compression (Shift: Amp Drive)
This permits the level of drive to the compressor, adjustable from 0 to 99:
<
CMP 0 (no compression)
<
CMP 99 (maximum compression)
This is a Shift parameter. To view or adjust it:
1) Press the Amp button and select column 2.
2) Double-tap the Amp button to enter Shift mode.
3) The screen will show the current Compression value. To change it, turn rotary control 2.
Use lower values to gently limit peaks. Use higher values to sustain your guitar notes, similar to increasing Amp Drive but without
the distortion that overdriving provides.
Amp Bass
This knob (#3) lets you control the amount of bass. The knob’s range and frequency follow that of the modeled amp and therefore
vary depending on the amp selected. The control range is from 0 to 99.
Amp Mid (Shift: Amp Bass)
To adjust Amp Mid, select Amp Bass then double-tap the Amp button. (See the “Additional Shift Parameters” section below.) This
lets you control the amount of midrange. The knob’s range and frequency follow that of the modeled amp and therefore vary
depending on the amp selected. The control range is from MID 0 to MID 99.
Amp Treble
This knob (#4) lets you control the amount of treble. The knob’s range and frequency follow that of the modeled amp and
therefore vary depending on the amp selected. The control range is from 0 to 99.
Amp On/Off
Hold the Amp button for one half second to bypass amp modeling entirely. When bypassed, the Amp Off icon will appear in the
LCD. Hold it again for one half second to re-enable amp modeling; the Amp Off icon will disappear.
