Appendices TROUBLESHOOTING Even though the GW10 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 GW10. PROBLEM The instrument (guitar) sound cannot be heard. POSSIBLE CAUSE AND SOLUTION • 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 and the Foot Controller). • Check that the Output parameter of the Distortion block is set to an appropriate level. • Make sure that the Tuner is not active. (See Tuner operation step #5, page 41.) The effect sound cannot be heard or is nearly inaudible. • Check all of the above points (for when the instrument sound cannot be heard). • Check that the desired effect blocks are turned on (LEDs are lit). • Check that the Mix, Depth and Range parameters of the Chorus and Delay blocks are set to appropriate levels. The sound is too loud or the effect sound is abnormal or unexpected. • The guitar level is too loud (the INPUT PEAK LED is lit continuously). Set the input level of the GW10 and the output level of the guitar appropriately. (See pages 13, 14). • 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. • If there is too much distortion or noise, check: • That the Drive and Output parameters of the Distortion block are set to appropriate levels. • That the Equalizer gain controls (Low, Mid and High) have not been set too high. • That the Mix parameters of the Chorus and Delay blocks are set to appropriate levels. • That the Noise Gate settings are appropriate. • Also check your connected amplifier. If you are getting too much distortion, check that the GW10 is connected to the clean channel and not to the distortion channel. 42 Appendices
