Main features
A new dimension of sound-
creation made possible by
three core sections: COSM
Guitar, COSM Amp, and multi-
effects
The COSM GUITAR section allows you to change the
guitar’s pickup and body. The COSM AMP section permits
the accurate simulation of distortion, amp head, speakers,
and mic placement. Finally, the versatile multi-effect section
lets you put the finishing touches on your sound.
Simply by pressing a single pedal, you can switch to a
different guitar, change the tuning, re-connect your amp, or
change to a different effects setup.
COSM guitar technology has been further developed to
allow the production of sounds that could not be made on
any previously existing instrument.
The vibrations from the guitar captured by the divided
pickups are analyzed to detect pitch and envelope, and are
used to create sounds that are totally new, yet have a natural
playing feel.
Your playing can take full advantage of the characteristic
nuances provided by guitar performance techniques such as
picking position, dynamics, and vibrato.
In addition, you can also use performance techniques from
which pitch cannot be detected, such as muting, harmonics
and brushing.
The COSM guitar section contains a mixer section that lets
you freely control the inputs of the normal pickup and the
divided pickup, so that you can create sounds that combine
both pickups.
Rich expressive potential
COSM guitar, COSM amp, and multi-effect parameters are
saved in each patch. When shipped from the factory, the VG-
88 contains 160 PRESET patches. In addition, 100 new USER
patches of your own creation can be stored in internal
memory.
The VG-88 contains a high-quality multi-effect unit.
Parameter settings for each effect can be modified and stored
individually in a patch.
The COSM guitar section provides a polyphonic pitch shifter
that allows you to specify a different amount of pitch shift for
each string. You can play VG sounds at a different octave
than the guitar sounds, or use open tunings without
physically changing the actual tuning of your guitar.
A four-band equalizer allows you to make detailed
adjustments to your tone.
Global parameters
The patch parameters of the VG-88 can be adjusted to
compensate for the environment in which you are playing.
Reverb depth, low-frequency and high-frequency tone, and
noise suppressor sensitivity can be adjusted globally without
changing the settings of each individual patch.
Easy operation
The VG-88 features the same all-in-one pedal effector-type
design that was so popular on the VG-8 and GR-30. There are
no complicated connections to make, and setup is quick and
easy.
The display consists of a two-digit LED and a full-graphic
LCD. The two-digit LED and the LED's for each number
pedal make it easy to distinguish patch numbers, even on a
dimly lit stage or when changing sounds from a standing
position. The 160 x 64 pixel LCD allows easy and visually
intuitive parameter-editing.
Operation is consistent and logical, so that you can
experience the power of the V-Guitar system immediately.
EZ Edit function (p. 26)
Starting with preset sounds, you can easily create new
sounds by adjusting four parameters.
Broad range of expandability
MIDI connectors (IN, OUT)
You can control the VG-88 from an external MIDI device. The
VG-88’s parameter settings can also be transmitted to an
external MIDI device and saved.
GUITAR INPUT jack
A normal pickup can be plugged directly into the VG-88.
GUITAR OUTPUT jack
If desired, you can output just the normal pickup sound of the
guitar.
SUB EXP PEDAL/SUB CTL 1, 2 jacks
An expression pedal or a control pedal can be connected to
these jacks. A connected pedal can be used for controlling
parameters.
Built-in EXP pedal and CTL pedal
The function of the built-in EXP pedal and CTL pedal can be
specified for each patch. For example, the EXP pedal can
function as a wah pedal in one patch, and a volume pedal in
another patch.
