Operation
Connect the guitar to the CG-series amplifier input using a good quality 6.3mm mono jack lead. Otherwise, if effect
pedals are to be used, plug into these first (unless they are to be used in the effects loop) and plug the output from
these to the input of the amplifier.
Connect the amplifier to the mains using the appropriate mains IEC lead supplied
If any external effects are to be used in the effects loop, connect the Send/Return jacks to the input/output of the
unit(s) and power up ready for use
Set VOLUME, GAIN and REVERB controls to the minimum (fully anticlockwise) position
Turn the BASS, MIDDLE, TREBLE and CONTOUR controls to the mid-way position
Switch on the POWER and switch the channel to CLEAN (make sure the DRIVE switch is off for CG-10). For CG-60
and CG-30, this can be achieved by plugging a footswitch into the 6.3mm FOOT SWITCH jack and pressing the
switch
Increase VOLUME for the clean channel and play a note, ensuring that the guitar’s volume and tone controls are
turned up. Continue increasing VOLUME until the required signal level is achieved
For CG-60, adjusting the left-most BASS and TREBLE controls adjusts the tone for the clean channel
Switch the CHANNEL or DRIVE switch to the overdrive channel or effect and turn up the GAIN to the desired drive
level whilst adjusting the VOLUME to balance the output level to suit. Note that higher gain and lower volume can
give more distortion.
Adjust BASS, MIDDLE and TREBLE controls to achieve the desired tone. On the CG-60, the CONTOUR control adjusts
the response curve of the mid frequencies
Turn the REVERB control up to the required level to introduce the internal spring reverb effect to the sound.
Plugging a line level source into the AUX twin RCA input mixes it with the guitar’s signal without adding overdrive or
tone shaping to the AUX signal. This may be a playback device, such as an mp3 player or CD player or even a drum
machine to play along with.
Plugging in a pair of headphones to the 6.3mm TRS Phones jack will allow silent practice by muting the speaker
output.
Before switching off or removing power, turn down the VOLUME controls.
When not in use, switch off and disconnect from the mains
