This section provides an introduction to the characteristics of each of the guitars modeled.
List of Guitar Types
ELECTRIC
ST
This is a solid body guitar with single coil pickups set in
three positions. The characteristically clear and delicate
sound is used in many musical genres.
LP
This is a solid body guitar with two separate humbucking
pickups. This type of guitar features a powerful sound with
good sustain, making it an indispensable sound for rock
music.
HOLLOW
This models the sound of a hollow body guitar with two
humbucking pickups. It features a sweet, boxy tone that is
used frequently in jazz music.
12 STRING
This models the unique sound of semi-hollow body twelvestring guitar equipped with two single coil pickups that was
a favorite of vocal groups in the sixties.
ACOUSTIC
STANDARD
This is the sound of an acoustic guitar with a flat top and
back.
12 STRING
This is the sound of an acoustic twelve-string guitar.
SPECIAL
SYNTH LEAD
This is an analog synth sound that is suitable for lead and
solos. This features a fat tone with a boosted midrange.
“SYNTH FILTER” (p. 16)
SYNTH PAD
This is an analog synth sound that is good for chord playing.
This sound features a wide range and gorgeous tone.
“SYNTH FILTER” (p. 16)
SLOW GEAR
This is an effect that is automatically applied according to the
way the guitar strings are picked to produce a sound
resembling that of a violin being played (see Note).
The VGA-3 processes each of the six strings independently,
allowing the type of performance expression impossible with
a conventional guitar.
(Note)
What is meant by “resembling that of a violin being played” is an effect
whereby the volume is reduced when the guitar is picked, and then it is
gradually brought back up.
POLY OCTAVE
This adds a sound one octave below the source sound.
Octaves are processed independently for each string,
providing a fat sound that is rich in expressive power.
“POLY OCTAVE STRING SELECT” (p. 16)
SITAR
This produces a sitar-like sound.

Troubleshooting
This section explains some things that might go wrong when using the VGA-3, and what needs to be done to correct the
problem.If you think there may be something wrong with your VGA-3, 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
Odd Sound / No Sound When Guitar Is Played
● Is the value for the [MASTER], [GAIN], or [VOLUME]
knobs, or for the [GAIN] or [VOLUME] settings stored
in the memory set to “0”?
➔ Raise the volume to a suitable level.
● Are the [BASS], [MIDDLE], or [TREBLE] knobs set to
“0”?
➔ Depending on the model selected with the Amp Type (p.
17), no sound may be produced when [BASS],
[MIDDLE], and [TREBLE] are all set to “0.”
● Are you using an expression pedal?
➔ There may be no sound produced when the pedal
portion is set to the released position. Try operating the
pedal.
● If controlling the volume with MIDI, was the MIDI
connection disrupted while the volume was set to “0”?
➔ Reconnect the MIDI device and raise the volume, or turn
the VGA-3’s power off and then on again.
Internal Effects Not Being Applied
● Is a foot switch connected?
➔ If the effect has been turned off with the foot switch, you
can turn the effect on by returning the knob to the “0”
position.
Wah Sound Not Produced
➔ An expression pedal (the optional EV-5) is required to
alter the filter used for the wah effect.
Interruptions in the Sound
● Is the noise suppressor effect set near “10” (higher
threshold)?
➔ Make a lower noise suppressor effect setting (p. 25).
The volume level of the instrument connected
to EXT IN is too low
● Could you be using a connection cable that contains a
resistor?
➔ Use a connection cable that does not contain a resistor.
● Is TUNER set to ON?
➔ Turn TUNER off, or set the volume to be used for the
TUNER function (p. 24).
● Is the unit in SYSTEM SETUP mode?
➔ Exit SYSTEM SETUP mode. Depending on the SYSTEM
SETUP parameters, sounds may not be output.
● Is there anything plugged into the RECORDING OUT/
PHONES jack?
➔ Disconnect the plug. No sound is output from the built-
in speaker when anything is plugged into the
RECORDING OUT/PHONES jack.
The COSM GUITAR sound isn’t right
● Is the GK pickup setting correctly?
➔ Check the GK pickup setting (p. 11).
Other Problems
VGA-3 Receives Commands from Foot Controller or
Other Device, But Memories Do Not Switch
● Is the external device transmitting over a MIDI channel
that cannot be received by the VGA-3?
➔ Set the MIDI channel on the external device to Channel
1. Otherwise, set MIDI OMNI MODE in the VGA-3’s
MIDI settings to ON (p. 26).
Tuner Meter Indicator Flashes With MIDI
Device In Use
● Could the external MIDI device have transmitted a
large volume of data all at once?
➔ After the indicator flashes for a short while, the VGA-3
automatically returns to the condition it was in before
receiving the data. Reduce the amount of data that will
be transmitted by the external device, then have it send
the data again.

* Wherever a block contains one or more icons, it means that some of the parameters of that block can be controlled using the external
controller(s) that the icon(s) represent(s).
* An EFX effect is placed either before or after the COSM amplifier, depending on the effect selected. WAH is before, and others are placed
after.
