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
Troubleshooting
No output and no Power light
Check POWER switch is on and mains lead is connected properly
Check mains fuse hasn’t blown
Power LED lit but no Output
Check that GAIN, EQ, VOLUME and guitar controls are not turned fully down
Check that headphones are not left plugged in
Change jack lead to check if faulty, also for Send and Return jacks
Check battery is OK in effects units in the Send/Return loop
Output too distorted
Reduce GAIN & EQ controls and increase Master volume to compensate
Check that overdrive channel is not selected instead of clean
Output very quiet
Check that GAIN, EQ, VOLUME and guitar controls are not turned down
Unplug effects from Send/Return loop to check if they are cutting signal level
