If You Think There Might Be a Problem (Troubleshooting)
This section explains some things that might go wrong when using the VGA-7, and what needs to be done to correct the
problem.If you think there may be something wrong with your VGA-7, please check through the following first.
If these suggestions don’t fix the problem, then go ahead and contact the store you bought it from, or your nearest Roland Service
Station.
■ Trouble with the Sound
The sound isn’t right.
● Is the divided pickup setting correctly?
→ Check the divided pickup setting. (p. 15–19)
● Is the selector switch on the GK pickup set to
“GUITAR”?
→ Set the select switch to a setting other than “GUITAR.”
There is no sound when the guitar is
played.
● Is the divided pickup connecting correctly?
→ Check the connections are correct. (p. 12)
● Is the SYNTH VOL on the GK-2A set to “0”?
→ Raise the volume to an appropriate level.
● Are [MASTER], [GAIN], or [VOLUME] on the VGA-
7 set to “0”?
→ Raise the volume to an appropriate level.
● Are [BASS], [MIDDLE], and [TREBLE] all set to
“0”?
→ Depending on the amp type (p. 28), there may be no
sound if you set the [BASS], [MIDDLE], and [TREBLE]
equalizer settings all to 0.
● Are you using the expression pedal?
→ If the expression pedal is returned (toward yourself),
there may be no sound. Advance the pedal (away from
yourself).
The pitch isn’t right.
● Is the guitar in tune?
→ Tune the guitar. (p. 21)
● Is the VGA-7 out of tune with other instruments?
→ Adjust the Standard pitch setting. (p. 20)
●
Have you set TUNING or CAPO for the COSM GUITAR?
→ Set the TUNING of the COSM GUITAR to NORMAL,
and turn CAPO off.
The volume fluctuates from one string
to another.
● Are the Sensitivity settings for all strings correct?
→ Adjust the settings if necessary. (p. 17)
Onboard effects are not applied.
● Is the effect turned “OFF”?
→ If an effect is turned “OFF,” that effect will not be
applied. Turn the effect “ON.”
● Are the effect levels high enough?
→ An effect is not applied and only the original sound is
heard when the effect level is at the lowest setting. Set
the effect level to an appropriate value.
Depending on the guitar being used,
hum may be audible.
● Is the output jack on your guitar connected to the
NORMAL GUITAR input jack on the GK-2A?
→ You should be sure to make this connection even if the
guitar sound is not to be output. For more details, see the
Owner’s Manual for the GK-2A.
