Troubleshooting
If there is no sound or other operational problems occur, first
check through the following solutions. If this does not
resolve the problem, then contact your dealer or a nearby
Roland service station.
Troubleshooting Problems with
the Sound
No sound/volume too low
❍
Are the connection cables broken?
→
Try using a different set of connection cables.
❍
Is the GT-8 correctly connected to the other devices?
→
Check connections with the other devices (p. 13).
❍
Is the connected amp/mixer turned off, or the volume
lowered?
→
Check the settings of your amp/mixer system.
❍
Is the OUTPUT LEVEL knob lowered?
→
Adjust the OUTPUT LEVEL knob to an appropriate
position (p. 14).
❍
Is Tuner set to On?
→
When the volume is set to “Mute” in the Tuner mode,
even the direct sound will not be output by setting the
Tuner to “On” (p. 77).
❍
Is each effect set correctly?
→
Use the “Meter function” (p. 75) to check the output level
of each effect. If there is an effect for which the meter
does not move, check the settings for that effect.
❍
Is “FV: Level” or “MST: Patch Level” specified as a pedal
assign Target?
→
Move the controller to which it is assigned.
❍
Is the power to the external device connected to the
SEND/RETURN jack off, or is the volume of the device
turned down?
→
Check the settings for the connected device.
The volume level of the instrument
connected to INPUT and RETURN are
too low
❍
Could you be using a connection cable that contains a
resistor?
→
Use a connection cable that does not contain a resistor.
Patch does not change
❍
Is something other than the Play screen shown in the
display?
→
On the GT-8, patches can be selected only when the Play
screen is displayed. Press [EXIT] to return to the Play
screen (p. 14).
No change in preamp tone even after
switching patches
❍
Has the GT-8 been set to “System” (p. 71) in Preamp
mode?
→
When the GT-8 is set to “System” in Preamp mode, the
preamp settings do not change when patches are
switched.
To make different preamp settings for individual
patches, choose the “Patch” setting in Preamp mode.
Unable to change parameters with the
knobs or PATCH/VALUE dial
❍
Are you using the Internal Pedal System (p. 61) in
Assign?
→
When the Assign Source is set to “Internal Pedal” or
“Wave Pedal,” the effect parameter set as the Assign
Target changes automatically.
If you want to be able to change the parameters
manually with the knobs and PATCH/VALUE dial, first
switch off Assign to deactivate the Internal Pedal
System.
❍
Is “INPUT LEVEL” (p. 60) set as the Assign Source in
Assign?
→
When “INPUT LEVEL” is set for the Assign Source, the
effect parameter set as the Assign Target changes
automatically according to the level of the input from the
guitar (the playing dynamics).
If you want to be able to change the parameters
manually with the knobs and PATCH/VALUE dial, first
switch off Assign.
