1.2 Control elements

1.2.1 Front panel

1
INPUT is the GX108's 1/4" jack input for your guitar. Use a commercial
1/4" jack mono cable with good mechanical and electrical shielding.
2
The GAIN control governs the degree of distortion produced by your GX108.
+
As high gain settings result in an output signal with plenty of treble
frequencies, it might be necessary to adapt the high-frequency range
with the TREBLE control.
3
The LEVEL control determines the overall volume of the GX108.
4
The BASS control in the EQ section allows you to boost or cut the bass
frequencies.
5
With the MID control you can boost/cut the midrange frequencies.
6
The TREBLE control adjusts the upper frequency range.
7
Use the ON/OFF button to switch your GX108 on or off: the LED located
between the MID and TREBLE controls lights up when the unit is switched
on.
