Ha that was the first pedal I built too! IIRC while my internal trimmers look to be similar as far as position I think my JFET one is closer to the middle of the adjustment. Originally I tried adjusting by going off the extraneous phasing sweep that goes on while the pedal is on but no one is playing. On mine that noise is a bit louder then I wish it was. Adjusting that way was a mistake, I redid it strumming guitar in stand and making adjustments. Just got a scope and will check it with that at some point. Good job!
