ZenGlory not working

[rpark71]

Hi all,

So I've built a pedal, using a Zen Drive tagboard layout from madbean and wanted to modify slightly so it had a toggle switch to go from Zen Drive using the BAT41 diodes and cleaner clipping, a bit like Morning Glory, using red LED's - a 'ZenGlory'. So I used Gemini, then pedal course version of ChatGPT to verify the new v14 layout (attached, as is original layout from madbean). So built the pedal and power LED comes on, I get bypass sound when pedal on/off, but not effect sound. One of the red LED's is permanently lit, but goes out if with power to pedal, you touch sleeve to metal jacks or enclosure. ChatGPT (DIY Guitar pedal pro v1.3 via Wampler pedal course) has gone through various tests using multimeter and audio probe. The idea was to power this at 18v, which the IC can do, but in testing I've used 9v from isolated power. Here are measurements:

IC voltages: pin 1 4.7v; pin 2 4.7v; pin 3 4.5v; pin 4 0v; pin 5 4.6v; pin 6 4.7v; pin 7 4.7v; pin 8 9.4v

Q1 is S 3.6v; D & G 4.6v
Q2 is S 3.6v; D &G 4.7v

When using audio probe I got guitar signal (not effected) at input, at switch lugs and then it stopped at tag 7 on layout v14. I had got R2 and R7 resistors mixed up, but replaced C3, R2 and R7. I still have same problem. So thought I'd post here for any thoughts, as about to give in. I feel like it might be a ground issue somewhere...it always seems to be a ground issue with my builds!

Any help appreciated.

cheers, Rich
