Hello Everyone, Having some issues with a Green Bean build. Have everything wired up and experiencing a hum. Like a ground issue but I can't seem to diagnose. I checked all wiring and seems correct. Checked for bridges with none visible. Also, not getting any output. Do you have to use a stereo guitar cable if you are using a stereo jack?
ready to pull my hair out! :)

No stereo guitar cable needed.
It would help greatly if you could post the DC voltages (to ground) for all of the IC pins and the transistor legs. ;)
Some photos could help too.
Usually you don't have to use a stereo guitar cable for a stereo jack.
There are two reasons why you would use a stereo female jack: switching power when male jacks aren't in (see madbean's standarized wiring diagram) or because you've ran out of mono jacks :)

Does is hum when bypassed?
Do you get signal when bypassed?
Have you already boxed it?
Pics are helpful?
Check to make sure you didnt swap your input and output leads.
