ANALOG EFFECTS
Every Program has a set of analog effects whose signal routing order is always fixed. These analog
effects include Compression, Distortion, and a 7-band Graphic Equalizer.
Compression: Every Program in the GSP-2101 Artist has a dynamic range compression circuit
specially designed for use with guitars. Compression does exactly what its name implies; it com-
presses the dynamic range of a signal. It does this by turning signals down as they become louder.
After it makes the adjustment to the level, it boosts the overall signal back up. This can be used
to increase sustain, and tighten up guitar signal, and is particularly useful on clean sounds.
Parameters of the GSP-2101 Artist compressor are as follows:
Effect On / Off
: Turns the Module on or off. When Modules are turned off, their
Parameters are not displayed. To see the Parameters, you must turn the Module on.
Compression Ratio
: Controls the amount of gain reduction for a given input signal
level. This means that if RATIO is set to 2:1, every 2 dB increase in input level results
in a 1 dB increase in compressor output. Likewise, if RATIO is set to 5:1, every 5 dB
increase in input level will result in a 1 dB output level increase. The higher the RATIO
setting, the more compressed the output signal becomes. Ranges from 1.5:1 to infini-
ty:1.
Threshold
: Sets the minimum input level at which the compressor will engage. As
THRESHOLD is lowered, the compressor engages at lower input levels, causing the
apparent output level to decrease. Ranges in 5 dB steps from -30dB to -45 dB.
Output Level
: Adjusts the overall output level of the compressor. Ranges in 6 dB steps
from -6 dB to +6 dB.
Distortions: The distortion section of the GSP-2101 Artist is capable of producing six distinctly
different types of distortion: three are tube-driven (using 12AX7’s), and three are solid state.
Any one of these distortions is available in every 2101 Program.
Tube Distortions: We’ve provided you with two completly separate gain controls in the tube
section.
The first gain control adjusts how hard the guitar signal hits the first 12AX7 tube. This control
is very useful in compensating for different pickup strengths from your guitar. If one of your
guitars provides a very strong signal, you will hear more distortion than guitars with weaker pick-
ups. Use the first gain control to help match the distortion sound between the two guitars.
The second gain control adjusts how much gain is applied to the signal feeding the second
12-AX7 tube (the signal being the result of the first 12AX7 tube). This is where distortion really
starts to build. Thousands of tonal possibilities are available by using different combinations of
Gain1 and Gain2. Low Gain1 and High Gain2 settings produce more dynamic type distortions
while, the opposite provide more tones with more natural edge. Using high settings for Gain1
and Gain2, offer more than enough distortion for most applications.
The 2101 gives you three types of tube circuitry to choose from. Saturated tube offers tight, all
out gain possibilities. Distorted tube has less gain overall, and is a little looser in the bottom end.
It also has a little darker natural tone overall.
