Chapter 4 Introduction to Effects and Parameters
In this chapter you will find detailed descriptions for each of
the GS-10’s onboard effects, and the parameters used to
control them.
The sound being input to each effect is called the “direct
sound,” and the sound modified by the effect is called the
“effect sound.”
* Setting values for gain– and volume–related parameters in the
effects too high may result in oscillation.
PREAMP/SPEAKER (Preamp/
Speaker Simulator)
COSM technology plays an indispensable role in simulating
the distinguishing characteristics of various guitar amps in
the “Preamp” section, and is also used to simulate various
speaker sizes and cabinet constructions in the “Speaker
Simulator.”

To derive the maximum performance from the GS-10,
be sure to make the correct setting for INPUT SELECT
(p. 19), the one that’s most suitable for your setup.
You may not be able to achieve the expected effect if
this is not set correctly.
* Depending on the type of bass guitar you are using, you
may not be able to achieve the intended effect if the input
level to the GS-10 is excessively high. In such cases, lower
the volume or tone of your bass guitar.
