GFX-3 - 5000-1
■
No sound, or very low volume
• Is the power switch set to ON?
•Are [INPUT] jack and [PHONES/OUTPUT] jack
connected correctly to instrument and
amplifier?
• Is the shielded cable defective?
• Is the GFX-3 set to the mute condition?
• Is the master level parameter set to a low
value?
• Is the expression pedal pushed down?
For some patches, the expression pedal controls the
volume. Set it to a suitable position.
■
Sound is unnaturally distorted
• Adjust level and GAIN parameters of effect
modules.
• Set COMP/ ISO module to OFF.
When a guitar with high output is used with these
effects, unwanted distortion may occur depending
on the DRIVE module setting.
■
High noise levels
• Adjust ZNR parameter. If problem persists, try
reducing GAIN.
If BOOSTER or COMP/ ISO module is used,
try decreasing GAIN parameter of DRIVE
module.
■
Expression pedal on/off switching does
not work properly.
•Try the procedure described in "Calibrating the
Expression Pedal" on page 16.
■
Bypassed sound is unnatural
• The Energize works also in the bypass
condition.
Set the Energize to "oF."
