Effects And Parameters; Distortion Block; Overdrive/Distortion (Od/Dst); Compressor (Comp) - Yamaha GW10 Owner's Manual

This section briefly explains each of the effect types and their parameters. For
information on how to select effects and edit them, see the sections SELECTING
EFFECT PROGRAMS (page 24), CHANGING THE EFFECT TYPE (page 25)
and EDITING EFFECT PARAMETERS (page 26).
OD / DST DRIVE

COMP SENSE
The Distortion block features the following
effects: Overdrive, Crunch, Distortion, and
Compressor.

Overdrive/Distortion (OD/DST)

Drive
Determines the intensity of the Overdrive,
Crunch or Distortion sound. The higher the
value, the greater the distortion.
HINT For best results, set the Drive parameter
roughly between the 12:00 and 3:00 positions.
Type
Determines the type of distortion effect: Over-
drive, Crunch, or Distortion. Overdrive recreates
the warm, natural sound of a tube amp being
overdriven. Crunch is a rich distortion effect
ideal for power chords and Rock'n'Roll. Distor-
tion is a hard, more metallic distortion sound,
and is excellent for screaming lead lines.
The positions from minimum to roughly 10:00
correspond to Overdrive, from about 11:00 to
1:00 corresponds to Crunch, and from about 2:00
to maximum corresponds to Distortion. Within
each effect is also three separate settings: Low,
Mid, and High.
Crunch

Overdrive M

A definite change in the sound can be heard
when crossing the "line" between two separate
types or settings.

Output
Determines the output level of the Distortion

This should be set to an appropriate value

to avoid sudden jumps or drops in level when
switching the effect on and off.

Compressor (COMP)

The Compressor 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 Compres-
sor limits signals of widely varying loudness to a
dynamic range more suitable for use with the
other effects. For this reason, compression is
effective on guitar in smoothing out the level
differences caused by uneven picking technique.
Sense
Determines the threshold level of compression.
Compression is applied to signal levels above the
Sense point, while signals below this point are
unaffected. The minimum setting virtually
allows the entire signal to pass without being
compressed (minimum compression), while the
maximum setting applies compression to the
entire signal (maximum compression).
Attack
Determines the amount of time it takes for
compression to begin after an input signal is
detected. Longer attack times (when dial is
turned toward maximum) let through more of the
natural attack of the input signal.
Output
Determines the level of the Compressor sound.
Settings past the 12:00 position are used for
boosting the overall signal to an appropriate
level, since compression effectively lowers the
level of the sound.
