Troubleshooting

This section explains some things that might go wrong when using the VG-88, and what needs to be done to correct the problem.
If you think there may be something wrong with your VG-88, 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. 14, 18).
There is no VG sound when the guitar is
played.
❍ Are the audio cables and the GK pickup connected
correctly?
Make sure the connections are correct (p. 14, 15).
❍ Are the VG-88, guitar amp, mixer, and other equipment
switched on?
Make sure the power is turned on for all equipment.
❍ Is [VOLUME] on the VG-88 set to "MIN"?
Raise the volume to an appropriate level (probably
somewhere near the midway point).
❍ Is the selector switch on the GK pickup set to
"GUITAR"?
Set the selector switch to "MIX".
❍ Has the volume function been assigned to the
expression pedal and others?
If the volume function has been assigned to the
expression pedal and others, and the pedal is in the fully
returned position (toward yourself), there will be no
sound. Advance the pedal away from yourself.
The GK pickup's select switch does not switch
the signal
❍ Is the SYNTH VOL knob set to a setting other than
"MASTER LEVEL" or "PICKUP LEVEL"?
Set it to "MASTER LEVEL," "PICKUP LEVEL," or
"MIXER LEVEL" (p. 67).
The pitch isn't right.
❍ Is the guitar in tune?
Tune the guitar (p. 17).
❍ Is the VG-88 out of tune with other instruments?
Adjust the Standard pitch setting (p. 17).
❍ Has COSM GUITAR Pitch Shift been set?
Set an appropriate value for COSM GUITAR Pitch Shift
(p. 39).
The volume fluctuates from one string to
another.
❍ Are the Sensitivity settings for all strings correct?
Adjust the settings if necessary (p. 20).
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/GK-3?
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/GK-3.
The volume level of the instrument connected
to GK IN or GUITAR INPUT is too low.
❍ Could you be using a connection cable that contains a
resistor?
Use a connection cable that does not contain a resistor.

■ Other Problems

"BATTERY LOW" is displayed when the power
is switched on.
The internal battery for saving Patch and system
parameters is almost out of power. Replace the battery
soon to prevent parameters from being lost. Contact
your nearest Roland Service Station or the store where
you bought the VG-88.
Patches aren't switched when a Program
Change is received from an external device.
❍ Are the Program Change messages being received on a
MIDI channel other than the channel set for "MIDI
Channel" on the System MIDI screen?
Send the Program Change messages on the same channel
as the one set with "MIDI Channel."
❍ Is an invalid Bank Select being transmitted?
Make settings so that a Bank Number MSB that the VG-
88 can use is transmitted.
