GUITAR COMBO GTX30/GTX60
Control elements 5
Front panel2.1
The {1} INPUT socket is the 1/4" connector for your guitar.
Please use a standard 1/4" guitar cable.
CLEAN channel2.1.1
The {2} CLEAN CHANNEL LED lights up when the channel
is active.
The {3} VOLUME control determines the volume of the CLEAN
channel.
The {4} BASS control in the EQ section boosts or cuts the bass
frequencies on the CLEAN channel (GTX60 only).
The {5} TREBLE control adjusts the treble frequencies on the
CLEAN channel (GTX60 only).
Press the {6} CHANNEL button to switch between the CLEAN
and OVERDRIVE channels. The channel LED lights up when
the channel is activated. You can also switch between chan-
nels using the footswitch sold with all models.
OVERDRIVE channel2.1.2
The {7} OVERDRIVE CHANNEL LED lights up when the chan-
nel is active.
The {8} GAIN control determines the amount of gain applied
and hence the degree of distortion in the OVERDRIVE
channel.
The {9} BASS control in the EQ section boosts or cuts the bass
frequencies.
Use the [10] CONTOUR control for additional, highly charac-
teristic adjustment of the midrange, so as to easily create
traditional as well as ultra-modern guitar sounds.
The TREBLE control adjusts the treble frequencies.[11]
On the GTX60, the controls + {9}, (10) and (11) are only
effective on the OVERDRIVE channel since this amplier
has a dedicated equalizer for the CLEAN channel (see
also {4} and {5}).
The [12] VOLUME control adjusts the volume level of the OVER-
DRIVE channel.
FX section2.1.3
The [13] FX LED lights up when the effects processor is active.
Use the [14] FX PRESET control to select one of 16 effects.
Preset FX
1 - 4 Reverb
5 - 8 Delay
9 - 12 Chorus
13 - 16 Flanger
EffectsTab. 2.1:
The [15] FX LEVEL control adjusts the mix ratio between the
original and the effect signal.
The [16] TUBE push button activates and deactivates the VTC
Virtual Tube Circuitry.
Connectors and POWER switch2.1.4
The [17] CD IN connector allows you to connect the output
signal of a CD player, tape deck, or CD/MD walkman.
For example, you can play back music CDs or CDs ac-
companying a guitar tutor while practicing. This connector
can also be used as a LINE OUT output. In this case,
the guitar signal has no speaker simulation applied to it
and can be routed to an external amp. This will not mute the
built-in loudspeaker of the GUITAR COMBO.
The [18] LINE OUT/PHONES jack is for headphones connection.
Internal speaker simulation is applied to the headphones
signal in order to produce an authentic signal. The built-in
loudspeaker of the GUITAR COMBO is muted when this
connector is used.
The headphones output signal can also be routed to a +
mixing console or other sound reinforcement system. To
do so, connect the headphones output with the line input
on the mixing console. Use a standard cable with 1/4"
TS connectors. If hum problems occur, you may want
to insert a DI box, such as the BEHRINGER ULTRA-DI
GI100 or DI120.
At extremely high volume levels some headphones tend +
to produce distortion. Please turn the volume down until
the distortion is no longer present.
Use the [19] FOOTSWITCH jack to connect the 1/4" TRS plug
of the footswitch supplied with the unit. The footswitch has
three functions: to switch between the two channels, to turn
the FX on and off, and to activate and deactivate the tuner
(GTX60 only).
The [20] POWER switch turns your GUITAR COMBO on and off.
It should always be in the OFF position when connecting the
unit to the mains.
Please note that switching the unit off does not mean +
that it is fully disconnected from the mains. To discon-
nect the unit from the mains entirely, pull out the mains
connector. Before installation, please make sure that
the mains connector has not been damaged. If you do
not use the unit for an extended period of time, please
disconnect it from the mains.
Chromatic tuner2.1.5
The [21] TUNER push button activates and deactivates the
integrated tuner. You can also activate and deactivate the
tuner by keeping the EFFECT push button on the footswitch
pressed (GTX60 only).
The [22] DISPLAY shows the note played. A dot indicates that
the note played is a semitone higher (F. = F# (F sharp), G.
= G# (G at), etc.). The green LED lights up as soon as the
displayed note is in tune. Pitch variations above and below
the desired pitch are indicated by two LEDs on each side of
the green LED. The brighter these LEDs glow, the greater
the deviation. The reference tone A at 440 Hz serves as
standard pitch.

The [26] SPEAKER OUT jack (1/4" TS connector) is used to
connect to a loudspeaker. The minimum impedance is 8
Ohms (GTX60 only).
The [27] FX RETURN input is used to connect to the output of
an external effects unit with a shielded 1/4" TS connector
(GTX60 only).
The [28] FX SEND output is used to connect the input of an
external effects unit with a shielded 1/4" TS connector
(GTX60 only).
