Roland VG-99 Workshop Manual page 6

The phase setting adjusts the divided pickup's phase in relation with
your guitar's normal pickups. If the sound is thin or "hollow" when you
blend your guitar's normal pickup with a COSM instrument sound, try
an alternate GK PU PHASE setting to see if that alleviates the problem.
When the divided pickup sound is played by itself, the GK PU PHASE
setting will have no audible effect.
Roland divided pickups—as well as most non-Roland
9
divided pickup systems—have two onboard switches
for controlling various VG-99 functions remotely from
the guitar. The S1,S2 POS setting allows you to reverse
the control functions assigned to them if you wish. Press
the F6 button to choose the desired setting: NORMAL or REVRSE.
If you've selected GK-3 or GK-2A in Step 5, use the PAGE buttons to go
10
to Page 3 in the display. If not, skip ahead to Step 12.
Use the F knobs to set the distance from the GK pickup to each string's
11
saddle ("1st" indicates the guitar's high "E" string). To determine the
distance, use your measurement tool to measure from the center of
the GK pickup to the point where each string passes over its saddle.
GK pickup Saddle
The saddles on most electric guitars are movable, allowing each
string's length to be adjusted slightly so that it plays in tune up and
down the neck. This procedure is called "adjusting the intonation,"
and it's typically part of a standard guitar setup when your instrument
is serviced by a repair technician. If you have the intonation adjusted
any time after making the settings in Steps 10 and 11, make sure you
revisit those settings and adjust them if necessary.
Use the PAGE buttons to go to Page 4 in the display.
12
Set the input sensitivity for each string. Begin by playing the guitar's
13
first string in open position (unfretted) at the maximum force that
you'd normally play at. Watch the meter in the display, and adjust
the F1 knob so that the meter registers just short of its highest level
at the maximum playing force. Then, play the other strings in open
position one at a time and use the appropriate F knobs to enter the
sensitivity settings for each.
If you've chosen a piezo-type in Step 5, you can adjust the high and
14
low frequency tonality of the pickup's sound. To do so, use the PAGE
buttons to select Page 5 in the display. Then, use the F1 and F2 knobs
to adjust the LOW and HIGH sound parameters. Values in the "+"
range boost the selected frequency, while "-" values cut it.
