Error on the board, the notes on v3 point it out, it it's in the empty hole between tr1 and tr2 it grounds it.

Okay, thanks.  Just found that on the GPCB Forum.  It wasn't in the PDF I downloaded (or the schematic).

It's weird that you're getting 7.1V on your regulator and ICs.  Test your voltage either side of D4 and either side of R28.

Are you playing it boxed or attached to a test rig?  I built my original test rig with the Beavis Board-style voltage sag, and that control has bitten me on the butt more than once.
I learned from building gpcb boards, BOMS and directions are subject to change without notice, you have the check the website.

Note: If you have an V3 board and not V3B then you will need to run a single jumper wire along the backside of the board. That's it.
Connect a jumper from the 5V output pad of the voltage regulator (IC3) to the extra center pad for the trim pot.
the IC3 pad is marked "O" for Output, top right pad as viewed from the top, top left as viewed from the back of the board.

Got a working board if you want it.  You could trouble shoot from it and end up with two of them.
That'd be cool. I'm pretty sure at this point though, I just need to reflow, Those eyelets are so small.

your voltage regulator is only seeing 7 volts, if its from a battery maybe the battery is kaput?

looks like your trying to run this puppy at 7v.
it might not run at 7v?
It's a regulated 9v power supply.

Why are you jumpering between IC3 and TR1 on the back of the board?

What do you write in google to get artwork like that, couple of your latest built makes me think of Tool-ish stuff.
Something like that, yeah. What I do is google the name of what I'm building and look at art work. I've had this one for sometime now, just like the last one. If you come across neat stuff anywhere, save it.

Mine is an etched board in a 1590b. I have a love hate relationship with those. I don't like the power being next to the I input jack.

Built to stock, enjoy!

I need to start using smaller boxes! I wouldn't use priority express unless they were paying, wow

I thought it was to give it a different sound, there were a few different ways to build that one. I dont know what the differences were though.

Some of th eother wah pedals you can remove the Q trimmer and resistor. I've done this on a couple.

There's a hotcake overdrive that you can build to bluesberry specs. I've done that one, is it the same? it's tiny with only a few pieces.

With smaller pedals, first class is usually an option.  I generally pay a couple more dollars for priority, though.
Not even a dollar more for express, it;s like .50 here. I always use express to make sure I can track it.

I'm officially stumped, I built the swaw and it wont quack.. I get clean signal, but there a nice little shock if I touch the pots and my strings.

Jimmy, I'd love too.  Don't have have the tools or the skill set:) maybe when my kids are out of the house. 
I watched a kid shape the back of a neck with hand tools (time lapse photography) on YouTube.... Talk about skill.
I know with pedal building, I enjoy the process as much as the final product.  I imagine guitar building would be the same.

I'm Cool leaving that to the pros. I will just buy blank bodies and necks.

I wouldn't think so, usually whine is a power issue, or so I once read here.
