EFFECTS AND PARAMETERS

EFFECT SECTION
EFFECTS AND PARAMETERS
This section briefly explains each of the effect types and their parameters.
For information on how to select effects and edit the main and
sub parameters, see the sections "Selecting an Effect Type,"
"Editing Parameters" (page 44), "Selecting Effect Programs"
(page 51) and the "MEMORY EDIT MODE" section (page 53).
Note: The characters that appear in parentheses after certain effect and parameter names
in this section indicate those names as they appear in the LCD. For example, the title
"WAH + EQ (WAH, WEQ)" indicates that either WAH or WEQ are shown in the LCD.

COMPRESSOR

The Compressor block is especially effective
for guitar since it smooths out the "peaks"
and "valleys" in the sound. Compression
"squashes" the dynamic range of the signal,
making loud signals softer and soft signals
louder. Normally, the Compressor should be
put before the other effect blocks since it
limits signals of widely varying loudness to a
dynamic range more suitable for use with the
other effects. For this reason, compression is
also effective on guitar in smoothing out the
level differences caused by uneven picking
technique.
— Range: 1 ~ 14
Determines the amount of time it takes for
compression to begin after an input signal is
detected. Longer attack times (higher values) let
through more of the natural attack of the input
signal.

COMPRESSOR
— Range: –6 ~ –42 dB
Determines the threshold level of compression.
Compression is applied to signal levels above
the Sense point, while signals below this point
are unaffected.
— Range: 0 ~ 200%
Determines the level of the processed sound.
Settings above 100% are used for boosting the
overall signal to an appropriate level, since
compression effectively lowers the level of the
sound.
SETTING THE OUTPUT PARAMETER—In
general — for this effect and others —
set the Output parameter so that the
HINT
level of the sound is constant,
even when switching the effect on and
off. If the Output parameter (and the
Input parameter on other effects) are
set too high or low, you may get
unwanted sudden jumps in the level of
the sound when turning the effects on
and off, sometimes resulting in over-
loading of subsequent effects.
