Variable controls:
Rate
Adjust the speed of the phaser. From once every 100seconds to 100Hz.
Symmetry
Adjusts the shape of the control waveform. Fast rise-slow fall, Slow rise-fast
fall and anything in between. With the knob pointing to the middle the
waveform will be symmetrical. Check out the examples below:
Resonance
Adjusts the intensity of the phasing effect. This will go all the way to self-
oscillation, watch out!
Lower
Adjusts how long the phaser stays at the bottom of the waveform. From not at
all to 2 seconds. Think of it as freezing the frequency of your guitar at the
bottom of the phasing. Here is a triangle wave example:
Upper
Adjusts how long the phaser stays at the bottom of the waveform. From not at
all to 2seconds. Think of it as freezing the frequency of your guitar at the top
of the phasing.
Here is a triangle wave example:
