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.)

Check that the Input and Output parameters of the various effects
are set to appropriate levels. (In particular, check the sub

adjusting all parameters in the effect until you get the sound you
want.
