SECTION FOUR
About the Effects
The effects included with the VGS50 may require an explanation as to what they do
and what the different parameter adjustments mean. For this reason we have
included this section detailing the different effects and their parameters.
Effects Definitions
Compression -
A compressor is a tool used to limit the dynamic range of an
instrument. In other words, it sets a boundary for how loud the instrument will be
able to get. The nature of limiting the dynamics of an instrument tends to provide a
smooth, even texture to the sound of the instrument.
The VGS50 has three different compressor settings: Low, Medium, and High. These
different settings are determining the threshold of the compressor. The threshold is
the strength that the incoming signal must be before the compression will begin.
Distortion - Distortion is one of the most common effects in music today. What it
is basically doing is adding so much gain to the signal that it deforms or distorts the
wave form. In other words, distortion will make the incoming signal so strong that it
“squares off” the top and bottom of an otherwise rounded wave.
The VGS50 has 8 different distortion types to choose from: American Stack, Classic
Combo, British Stack, Overdrive, Grunge, Clean Valve, Blues Valve, and Saturated
Valve. Some of these distortions use the tube and some use transistors to achieve the
distortion. The distortions using the tube will be indicated by a lit Tube icon (9).
EQ -
An Equalizer is used to enhance a particular range of frequencies. It will either
boost, or cut specific frequencies in your signal. It can be compared to the tone
controls of a home stereo. The “High EQ” is the treble control, the “Mid EQ”
adjusts the mid-range frequencies, and the “Low EQ” is the bass control.
Noise Gate - A Noise Gate is like the name implies. It is a gate that will shut when
you are not playing, and open when you are playing. When the gate is closed, it will
not allow ambient noise to come through. A noise gate uses a threshold, which is
the level of volume that a signal must be in order to open the gate. If your guitar
signal is not strong enough to cross the threshold, the gate will not open, and no
sound will be heard. The gate on the VGS50 is also used for volume swells. When
you have selected the gate to act as a volume swell, you can strum your guitar, and
the sound will fade in.
Chorus -
A Chorus is an effect that adds thickness to your guitar signal. It is
splitting your guitar signal, adding a short delay to half of the signal, and then
changing the delay time at an even pace. This results in the pitch of the delayed
signal fluctuating slightly, giving the illusion of two guitars playing together.
