Posting out of curiosity as much as to perhaps providing 'the answer' to any other poor soul who finds themselves in my position.

so I typically use 2.1mm jacks on everything.  I bought the eh power adapter per spec for this build and captain obvious here took till now to figure out it employs a 2.5mm jack.  Now a 2.5mm power supply will physically fit into a 2.1mm jack... but ground will not make good connection... occasionally - your experience may vary. 

I don't know if they make this adapter in a 2.1 as well... but just wanted to post in hopes that perhaps someone might find the info as relevant as I am finding it right now.  cheers and thanks for - despite all my troubles - a very fun build.

using LT1054 charge pump, 2n5088, 2n5457, MC78L15ACP, LM1458N, V3207, CD4047BE
didn't really sub anything other than bbd and using two resisters in series to get r5/r4.

not a lot of opportunity for flux connecting two pads together other than a handful of pads that are really tight

I've checked orientation of electro caps.  at the reg I get expected 15v~

I do get clean signal with the chorus knob the right way and flange/vibe switch set right.
I've traced my signal to pin 3 on the BBD.  I checked the jumpers for MN3207 - looks right to me!
checking pins 7 and 8 of the bbd i get some kind of static.  I've swapped out for another mn3207 and same result. 

Q: looking at other posted voltages... it says pin 1 of bbd should be around 15v?  but this is the ground pin... am I missing something?  I see ~0v on mine.
looking at r36 I get correct voltage... depending on the bias setting I get 7v~ and 7v~ at the trim.

I could really use a pic of the tracks... I can read the schem and spot check... but it'd be real helpful in case anyone would be so inclined as to have mercy on my pitiful soul.

edit: solved


hello,
before you ask: yes, I prob bit off more than I can chew.  not a complete novice as I've built quite a bit but def finding this hard since I can't see the traces. 

I know I can't ask anyone to solve it for me... just sort of stuck and was hoping someone might give me an idea of what to check next.

i used the mouser cart for parts and seemed to have all I needed... did have some extra 24k but I may have ordered extra as it seems to be a common value. 
followed the build instructions and checked the dc jack, and regulator before I ever populated chips. 

what I've checked so far...
dbl checked that the mn3005 is oriented correctly to the solder mask.
-15.14 at regulator (-21.7 coming in)
-15.14 at pin 5 of ic6 -6.8 at pin 3/4
dbl checked all electro orientation
dbl checked d1 orientation
signal checked leading up to pin 7 of ic6... plenty of clean signal at pin 7 with level set to 40%

i have a couple of extra xvive mn3005 from smallbear, swapped out chips to check... sm result.  unless I got a couple of bad chips... but I'm not sure what the effect is when you have a bad chip... do you get a high pitched signal at pin 3/4?  i had initially worn a shock band while installing... ensured I grounded myself when swapping.

any help would be appreciated.
