Edit Parameters
9 Chorus
10 Flanger
11 Phaser
12 Tremolo
These are the standard modulation effects. The chorus modulates a left and right delay to create
a detuned doubling. The flanger uses a shorter delay and feedback to create a modulated comb
filter. The phaser uses modulated all-pass filters to create a different type of swept comb filter. The
tremolo effect is the traditional amplitude-modulated effect.
Parameter 1 (Speed)
– Rate of modulation, 0-99%.
Parameter 2 (Depth)
– Intensity (width) of modulation, 0-99%.
13 Rotary
This effect simulates a two-way rotary speaker cabinet popular with organists (but is very useful
on guitar and other signals). The signal is split into low and high frequencies and modulated
separately and at slightly different speeds.
Parameter 1 (Speed)
– Rate of modulation, 0-99%. Pressing the footswitch will allow you to toggle
between two speeds, and you can set these low and high speeds however you want. (One of the
speeds will be shown with the decimal point, and the other without.) The Rotary effect will ramp
the speed between these values, just like a real rotating speaker.
If you want the footswitch to still act as a defeat, set either speed to “oF” for off, and the Dual
DeltaFex
®
will enter Defeat (Bypass/Mute) mode instead of toggling the speed. (When editing
Rotary, pressing the footswitch will always toggle the speed values to allow you to change the “oF”
back to a real speed value.)
Parameter 2 (Depth)
– Intensity (width) of modulation, 0-99%.
14 Distortion
The Distortion effect consists of a digital distortion followed by a tone section, then an optional
speaker simulator for full-range systems (which removes a lot of the treble frequencies that a
typical guitar cabinet does not reproduce). This effect does have a mix, which is something you
don’t get with most distortion devices.
Tip:
Experiment with running some dry sound along with the distortion to regain some note
definition.
Parameter 1 (Drive)
– The amount of gain, or distortion amount. Range: off, 0-10 (choose off to
bypass the distortion and use the tone and speaker simulator by themselves).
Parameter 2 (Tone)
– This cuts high end as you turn it down, like a tone knob on a distortion pedal.
Range: 00 - 99 (non-cab simulated), then 00. - 99. (cab simulated).
