Can't say 100% verified yet, the mode switch and controls work.

I was able to calibrate the 0.45v, but the speed switch didn't seem to be working. The LED ramps up as it should, but the resistance on H11F1 pins 4-6 doesn't change. Will get back to it asap.

But, the delay itself sounds great.

Note: apparently the input of the PT2399 will be overdriven if the voltage at pin 7 goes above 2v. That's the reason for the added green LEDs on pin 7, to keep the voltage at pin 7 below 2 volts. I mention it because on mine, the LED on the rightmost PT2399 is lighting often. Curious if anyone else experiences the same. ( I'm using a Tone Zone humbucker)
