Current Lover Calibration

Hey all I'm building a 2015 Current Lover, and I'm having a difficult time with the calibration. I've followed the instructions in the build guide thus far, but I'm having a hard time finding a good spot on the bias trimmer. I'm getting either no flanging at all or noise. The build guide references a "chirping" sound at the extremes, but what I'm getting can only be described as an earsplitting squeal. I can crank the volume down and just let it squeal without blowing out my ear drums, but there's no place within the range of the clock trimmer that I can eliminate that noise. If however I skip ahead in the process a bit and adjust the T1 trimmer clockwise I can eliminate the squeal, but then the guitar signal is distorted (I'm playing a fender with humbuckers) I tried to replace R1 with a larger value, but that hasn't cleaned up the sound at all. I know that the clock trimmer is supposed to be important to the calibration process according to the build guide, but it seemingly has almost no effect. I've tested the voltages at all of my IC pins. I'm in the right neighborhood on all but the 7th pin of IC5. The build guide says that pin should be at 7.8v, but I'm reading 0. I took a look at the circuit diagram and the way I'm reading it  it doesn't even look like pin 7 is connected to the circuit. The indicator LED is also lit up even when the pedal is disengaged. Is that normal? Those are my only two clues that something might be wrong with my build, but I don't know what to make of them. There might be nothing wrong for all I know and this is just how the pedal sounds when you play high output humbuckers through it (I don't have a guitar with single coils). I've got a picture of the build, but it's too big to attach and I'm embarrassed to say that I can't figure out how to get it into the post. Any help is appreciated. Thanks
