Question - No signal on output?
On some specific user presets there is no signal in the
output, although the Input VU-meter shows that signal is
entering the unit.
Answer
This can occur if you set the Insert loop to "on" without
having anything connected to it. Please set the insert
loop to "off".
Question - G-System directly into a combo?
Is it possible to use the G-System straight into the front
end of a small combo guitar amp without the use of a pre
amp?
Answer
Yes this is possible, if the amp is used as a "power amp".
If you need to use the drive of the combo, the pre-amp
section of the combo should be inserted in the Insert
loop of the G-System (loop 5) to take full benefit of the
post effects of the G-System.
Question - How do I adjust the Input level?
What is the proper way to adjust the input level on my
G-System? Should the meters be almost clipping?
Answer
You should leave some headroom (around 3dB) on the
Input meter to avoid internal DSP overloads.
A DSP overload can happen anytime though, depending
on how much you boost the signal inside the unit. If you
boost the signal too much internally, the LEDs will light
up, even though the input is not too loud.
You should be careful not to overloading the DSP. In
analog equipment, overloads can produce harmonic
distortion, which can make the sound "warmer". In digital
equipment overloading just degrades the sound and
creates loud clicks!
Question - Global bypass?
How can I bypass the G-System?
Answer
There is no Global Bypass parameter in the G-System.
But you can assign an 'empty' preset to any
customizable switch. The factory preset B9-5 is an “all-
bypassed” preset.
Question - Control of several GFX01
Can one single G-System board control several GFX01
(the 1 unit processing module that is mounted under the
G-System board itself)?
Answer
No, this is not possible. The G-System board can only
control one GFX01 unit. However, via MIDI the G-System
can send certain MIDI messages to other MIDI
compatible devices.
Question - Volume Min value
My expression pedal is set to control the Volume
parameter and though the Min. parameter is set much
higher than 0, the “heel-down” position is still equal to “off”.
Answer
This is intentional and how most people want the Volume
control to work. If you need a minimum value different
from “off” in “heel-down” position, we suggest you use a
volume/expression pedal with an adjustable minimum
value.
