Boss Audio Systems GS-10 PREAMP/SPEAKER Preamp/ Speaker Simulator, On/Off Effect On/Off

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.

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.
