Hey guys, I built two pork barrels side by side. One works and one doesnt. I checked Transistor voltages of the one that doesnt work and they are all fine, compared to voltages posted by other successful Pork Barrel builds.
IC voltages all look good except:
pin 7 of the 4558, is 1.5V
pin 7 and 8 of the MN3007 is 3.2 volts
Im wondering if the 4558 is affecting the MN3007 or vice versa. Either way I get bypass, but no effected signal.
Any help would be great.

Just noted that the VB side of C6 gives me VB....4.6V The other side of C6 gives me the 1.5V that I am seeing at pin 7 of the 4558. Hmmm wondering if my C6 cap is bad?
Pulled C6 out...tested the cap on my cap tester and nope value is good...110pf is what it measured out to be.
Any thoughts guys???
Have you checked via audio probe to verify you are getting signal into pin3 of the MN3007 and out of 7&8?
If you are getting dry signal out when the effect is engaged then this is the first place I would look.

I have not used my audio probe as of yet. Just checked voltages, but I will do some probing and report back. Thanks for the help.
