SECTION ONE - Introduction
A Guided Tour of the GS30
Front Panel
Program Footswitches - These switches provide access to the GS30 user presets. They are also
used to bypass the GS30, access the Tuner, and perform various functions
for the Learn-A-Lick feature.
2. Bank Footswitches - These two switches are used to advance or reverse the currently selected Bank.
The Bank Up switch is also used to access the Learn-A-Lick mode.

3. Edit Section - These columns and buttons are used to select, bypass, and edit each specific effect group.
The effects which are currently active within a preset are indicated by a lit LED. The button
at the bottom of each column will select the effect group within the indicated column.
Successive presses of the same button will advance to the next type of effect within that
group. The currently selected effect will be represented by a flashing LED. The effect
groups include Compression, Wah, Expression Pedal, Amp/Guitar Modeling, Tone and
Gate, 10 Modulation/Pitch Shift Effects, Delay, and Reverb.
4. Parameter Section - This column represents the various aspects of the Mod/Pitch, Delay, and Reverb
Effects which can be fine tuned to suit your application. When any of these three
effect groups are selected, the associated parameter LEDs will light indicating
that you can fine tune these aspects of the selected effect. The parameters are
selected with the button at the bottom of the parameter column, and the
selected parameter will be indicated by a flashing LED. Successive presses of the
parameter button will advance to the next available parameter. Once the desired
Parameter has been selected, the current value will be shown in the display (7),
and you may adjust the value of the parameter with the Data Wheel (9). The
Parameter LEDs also serve as sharp and flat indicators in the tuning mode.
5. Tuning LEDs - The In Tune LED works in conjunction with the parameter LEDs while you are in Tuning
mode. Once the Tuner has been accessed, the Display (7) will show the note being played
and the parameter LEDs will indicate whether you are sharp or flat of the displayed note.
Parameter LEDs above the In Tune LED indicate that you are sharp and need to tune
down. Parameter LEDs below the In Tune LED indicate that you are flat and need to tune
up. Your note is in tune when the In Tune LED is the only one lit.

6. Speaker Simulator - This button is used to engage or disengage the Speaker Simulator. The LED will
light when the Speaker Simulator is engaged.
7. Display - The Display serves four functions. In performance mode, the Display will indicate the Bank and
Preset that is currently active. In edit mode, the Display will show the status or value of the effect
or effect group being edited. In Tuner mode, the display will show the note played. In Learn-A-
Lick Mode, the Display will show the status of the function, and the selected play back speed.
8. Store Button and LED - After editing a Preset, your modifications must be stored in order for the
GS30 to remember the changes that you made. When you change any
aspect of a Preset, the Store LED will light indicating that you need to use
the Store button to save the change.
9. Data Wheel - This knob is used to select the Preset in performance mode, and to increase or decrease
the value of a Parameter in the edit mode. It is also used to change the tuning reference
in Tuner mode.
0. Expression Pedal - This pedal can be assigned to control one of 9 different Parameters in real time
for each Preset. As you rock the pedal back and forth, the value of the assigned
Parameter will change giving you expressive control over the effects.

Rear Panel
