10-stage phaser
The Analog Custom Shop Phase Shifter is a 10-stage phaser, which can result in some deep sounds with deeper, more resonant effects or subtle harmonic sweeps.
A/B SWITCHES: These two switches can be set in a total of four combinations, which are shown next to the switches themselves – 90, 180, 270, and 260. These settings indicate the intensity of the phasing. The 90 position creates a subtle phase while the 360 position creates a much more resonant, deep phasing sound.
RATE: Turn this knob to adjust the rate of the effect (how quickly the phasing occurs).
BYPASS SWITCH: Step on this switch to turn the effect on or off. This pedal features a true bypass switch, meaning your signal won't be colored by the pedal's circuitry when the effect is off.
