HUSH THRESH
GLB OFFSET
You may find that the HUSH is not even needed for tones created with the Clean American voicing
or the Texas Blues voicing when using a low gain setting. As you move into a higher gain Texas
Blues setting or the Vintage British and Mega Drive voicings, the gain rises and so does the noise
floor. The higher the Gain parameter of these voicings is set, the more noise you'll hear. Before
turning on the HUSH and adjusting the HUSH threshold, make sure you have the preamp gain and
EQ settings the way you want them for that preset, then engage the HUSH.

To properly set the HUSH THRESHOLD:

Set the Threshold level so that your signal remains open during the quietest notes or decay's that
you'll be playing, yet shuts down tight when you mute your strings.

Using different guitars:

It is also important to note that if you switch guitars during a performance and those guitars have a
different output level, you should quickly use the INPUT LEVEL control on the face of the unit to
set a proper input level for each guitar. This will allow your preset HUSH Threshold settings to
work the same for all guitars. You may also use the GLOBAL OFFSET to fine tune the HUSH
Threshold settings for all presets.

The HUSH parameter determines whether the HUSH
current preset. (Off, On)
The HUSH THRESHOLD parameter determines the level at which downward
expansion begins. For example, if the HUSH THRESHOLD was set at -20dB and
the input signal dropped below -20dB, downward expansion would begin. (-90dB
to -27dB)
The GLOBAL OFFSET parameter allows you to globally (all presets) adjust the
®
HUSH expander threshold. This means that if this parameter is altered from 0dB
to +3dB, the expander threshold will become 3dB higher for all presets. This
feature is useful when switching from a quiet guitar with passive electronics to a
noisier guitar with active electronics, as the guitar with active electronics would
require a higher threshold level in all presets. (-10dB to +30dB)
