So I redid the whole board layout and ordered another proto in and it has the same problem :( I can hear the subtle swooshing of the LFO when I turn up the blend and the rate and depth, I think that section is working correctly. I did another trace of the audio using my audio trace and found...

Thanks for taking the time to review everything. I appreciate it. That's wild that JLC can install the incorrect values or wrong orientation - never thought to question it. In this case, I went through and checked C13/D5/D6 and they are oriented correctly. I went through all the LFO section and...

Hi all! First off, this is my personal build and not a PPCB project. If that is not allowed here let me know! I am really stumped on this one. I designed my own layout and circuit board and it has been assembled with SMD components by JLC so I am confident that the component values are correct...

Yup, I should have known better instead of trying to save a few bucks. Thanks for all the help. I will update this thread when the new IC comes in from Small Bear to see if that was the issue here.

https://www.ebay.ca/itm/201401342602 I looked at the "100% Genuine" in the title and the good feedback from the seller and took a chance on it.

The display goes down to 000 when you touch the leads together in the diode setting, similar to the resistance settings. I checked the scratched copper against the pad and no short. I just ordered another IC from a reputable company to try, this time a CA3080e for $7. The CA3080ez I have in...

I have this DMM, any idea if it can detect shorts?

Better angle

I do not unfortunately

There is 9.8K ohm resistance between the circled C pad and the tiny bit of scratched copper next to it. Reflowing the other circled pad didn't help

Nope, just checked. Even took it out of the enclosure to check and still nothing..

Thanks for the reply. 1. Yup, I double checked the caps, all correct! 2. Yup, I didn't have a 92K on hand so I put two 47Ks in series.
