* With some patches, a certain amount of noise may be audible if
you turn the knobs while playing your guitar.
GAIN:
Adjusts the distortion. Turn the knob to the right (clockwise)
to make the distortion stronger; turn to the left
(counterclockwise) to decrease the distortion.
TONE:
Adjusts the tone brightness. Turn the knob to the right to
boost the higher frequencies to create a crisper sound; turn to
the left to boost the lower frequencies and create a deeper
sound.
MODULATION:
Adjusts the spacial effects (such as chorus, flanger, etc.)
Turning the knob to the right strengthens the effect; turning
it to the left reduces the effect.
DELAY:
Adjusts the echo (repetition of sounds). Turning the knob to
the right increases the echo; turning it to the left reduces the
echo.
REVERB:
Adjusts the amount of reverberation in the sound. Turn the
knob to the right to increase the reverb; turn it to the left to
reduces this sound.
LEVEL:
Adjusts the overall volume level. Turn the knob to the right
make the sound louder; turn it to the left to reduce the
volume.
* A dot lights up in the lower right of the Bank display when a
tone is being altered. This indicates that additional changes
have been made to the patch's tone. However, tones that have
been changed are only held tentporarily, and are lost once you
switch to a different tone (Patch Change: p. 11). If you want to
be able to use an altered tone again, carry out the Write
procedure (p. 15) and save it toa User patch.
