(See pages 99 and 102.) s Check all of the above points (for when the instrument sound cannot be heard). s Check that the desired effect blocks are turned on (LEDs are lit). s Check that the Effect Mix and Dry Level parameters of the Chorus and Reverb/Delay blocks are set to appropriate levels. (See pages 64-69.) s Check that other effect parameters (such as Depth in the Chorus, or Reverb Time in Reverb) are set to appropriate levels. s The guitar level is too loud (the INPUT PEAK LED is lit continuously). Set all levels appropriately (see page 21). s In general, remember that the parameters within an effect interact with and depend on each other. If you are using more than one effect, try each effect block separately, checking and adjusting all parameters in the effect until you get the sound you want. 114 TROUBLESHOOTING

Even though the GW50 is exceptionally easy to use, it may occasionally not
function as you expect it to. Note that the problems covered here are not
malfunctions of the GW50. (Also refer to the “ERROR MESSAGES” section.)
PROBLEM
POSSIBLE CAUSE AND SOLUTION
The instrument (guitar) sound cannot be heard.
■
Check that all connections have been properly made and that
all levels have been appropriately set (including the INPUT
LEVEL control on the rear panel).
■
Check that the HEADPHONES LEVEL control has been set to
an appropriate level (if using headphones).
■
Check that the Input and Output parameters of the various effects
are set to appropriate levels. (In particular, check the sub
parameters of the Equalizer block effects.)
■
Make sure that the Effect Mix and Dry Level parameters are set
appropriately. When they are set to 0, no sound is output.
■
Make sure that the MIN/MAX Volume function is not active
(and that the Minimum Volume setting is not 0). (See page 48.)
■
If an external foot controller is connected, make sure that it is not
all the way up (at the minimum setting).
■
Make sure that the Tuner mode or MIDI Bulk Dump functions are
not active. (See pages 99 and 102.)
