Main Features
The VGA-7, a V-guitar amplifier with a GK input, affords a new dimension in sound-creation potential, through its
combination of COSM guitars, COSM amplifiers, and effects. Additionally, if offers a memory storage feature, and
stereo output (65 + 65 W).
The two-way speaker system provides 12-inch speakers and horn tweeters in a bass-reflex cabinet, producing richly
expressive sound over a broad range, from powerful lows to sparkling highs.
COSM Guitar
● The pitch and envelope data that the divided pickup
extracts from the guitar’s vibrations are used to create 26
types of realistic tones, ranging from standard electric
guitar to acoustic guitar, and on–to even completely new
dimensions in sound.
● You can switch pickups and pickup position as
appropriate for the type of guitar. For acoustic guitars,
you can select piezo pickup or mic’ed sound.
● The Tuning function (six-string independent) provided
by the VGA-7 allows you to play in open tunings or
Nashville tuning without changing the actual tuning of
your guitar. You can also switch instantly to 12-string
guitar tuning.
Each individual string can also be tuned freely.
● Digital Capo function lets you use hitherto-impossible
“negative” fret settings.
COSM Amplifier
● In addition to classic, solid-state and vacuum tube units,
full-range amps ideal for acoustic instruments are also
provided, giving you a total of twenty different guitar
amp sound simulations.
● Gain/volume/3-band equalizer/presence controls let
you fine-tune your sound even more. All of these
functions are adjusted according to the unique
characteristics of each amp type.
● Speaker Modeling function simulates the characteristics
of different cabinets. You can use simulations of classic
models of speaker cabinets, or combine speakers and
cabinets in new and creative ways.
Effects
● Four kinds of effects are offered onboard: EFX, delay,
chorus, and reverb. All four can be used simultaneously.
You can also use a foot switch to switch each effect on/
off.
● As the EFX, one of the following six can be selected: wah,
slow gear, compressor, tremolo, phaser, or flanger.
● The delay supports tap input, making it easy to set the
delay time. The Delay Hold function lets you repeatedly
play back a recorded phrase.
● Chorus features the richly spacious air-mixed chorus
made famous by the Roland JC series.
Memory Storage Feature
A whole string of settings, calling for things such as a change
in guitar, in the tuning, in the amp, or a different choice of
effects can be stored as “patches” in memory. Then, during
performance, simply call up the patch, and you’ve instantly
selected just the settings you need.
In addition to eighty pre-programmed “preset” patches,
another eighty “user” patches can be programmed with your
own settings, for a total of 160 patches at your fingertips.
Easy Operation
Buttons and knobs are located for easy operation, making
everything from patch changes to sound editing quick and
intuitive.
