Phaser Section Controls
The Phaser section provides control over the effect’s center frequency and number of phaser stages (or Poles).
Center
The Center control lets you change the frequency center (100 Hz to 10.0 kHz) for the phaser poles.
Poles
Select the number of phaser poles (stages): 2, 4, 6, or 8. The number of poles changes the character of the sound. The greater the number of poles, the thicker and squishier the sound.
