mono (2 conductor) ¼” cable and press down on the expression
pedal, just like on a separate wah-wah pedal. For this to work, the
EXP SWITCH parameter within the EXP PDL function must be set
to WAH. The fourth way in which the WAH function is turned on is
by recalling a Preset with this WAH parameter set to ON.
2. WAH FREQ (500 Hz to 3084 Hz): The wah center frequency. A
wah-wah pedal is a peaking filter with user variable center
frequency inserted in the signal path. A classic Cry-Baby wah
pedal will have a typical frequency range from about 1000 Hz to
2800 Hz, so the range available here is greater. This frequency
can be adjusted by turning the VALUE knob, but the usual method
is to connect an expression pedal which has a linear potentiometer
(pot) to the EXP. PEDAL jack on the rear panel with a ¼” stereo
cable (3 conductor with ring-tip-sleeve or RTS plugs). The EXP
PDL1 or EXP PDL2 parameters must be set to WAH FREQ, and
the corresponding EXP MIN and EXP MAX parameters can be set
the minimum and maximum frequency values you want to sweep
over. This allows you to limit the range to equal that of a classic
wah pedal if you wish. But the MIN and MAX values you set will
only be reached if the pot in your expression pedal sweeps from 0
ohms to the full maximum resistance of the pot within the pedal,
which often is not the case. So the actual MIN and MAX values
you reach may cover a slightly reduced range. See also the
EXPRESSION PEDAL Function.
3. WAH LEVEL (0 to +10): Controls the level near the center
frequency of the wah. Since the wah filters off frequencies away
from the center frequency, the audible level will typically go down
when the wah is switched in. This allows you to boost the level
back. Clean presets will require more boost, while higher gain
presets will require less because the increased harmonic content of
the distorted signal will tend to fall within the passband of the wah
filter.
F) TREMOLO Function
A tremolo works by simple amplitude (volume) modulation of the signal. It
has a MONO output.
1. TREMOLO (OFF or ON): Turns it off or on. The tremolo can also
be turned on or off by pressing the switch marked
PHASER/TREMOLO, if the P/T SWITCH parameter within the
Switch function is set to TREMOLO or PHA+TREM.
2. TREM DEPTH (0 to 100): Controls the depth, which is the amount
of amplitude modulation.
3. TREM RATE (1 to 127): Higher numbers give faster rates. The
rate can also be controlled by pressing 2
nd
, then pressing twice
