Circuit diagram and schematic for manually operated phase pedal

[recordbuff]

Could someone put a link for a schematic and circuit diagram for a manually operated guitar phase pedal. One that does not oscillate and is just controlled by depressing a foot pedal with a variable resistor? Thanks in advance.
