Failure to launch

Hi folks,

I put together my pedalshield a couple days ago, and have yet to get it working.

With the guitar and amp connected and usb power I can't get any bypass at all. No matter the switches, dials, or sketch, nothing is getting from the input to output.

I loaded the sine wave and metronome sketches, and have almost no output. With the amp turned all the way up I can hear the tone behind a lot of static. It changes frequency as it should, though. I can barely hear the metronome at max volume, but the led responds appropriately. The tone does not go away when I hit the footswitch, but there is a lot more static on one of the settings.

When I went to install the footswitch, it didn't fit in the pcb holes. It was close enough that with some bending I was able to get it mounted. It is from mouser, I pulled the part number off the pedalshield BOM.

With USB power, nothing connected I am getting
U1
1 1.6v
2 1.6v
3 drifts from .4-1v usually around .8v
4 -4.5v
5-7 1.6v
8 5v

U2
1-3 0v
4 4.5v
5-7 0v
8 -5v

U3 (power)
1 5v
2 0v
3 0v
4 -1.8v
5 -4.5v
6 1.4v
7 2.8v
8 4.9v

I've been over the board several times, checking components and resoldering. I'm a mediocre solderer, but I can't find any shorts or opens and have touched up the suspicious ones. I wonder if my footswitch has a different pinout than the one shipped with the kit? The center 3 leads are common, and connect to either the left or right 3. From the trace it seems like the switch never directly connects the two jacks for a "true bypass"?

Any advice or feedback welcome, thanks for your time.

Thank you very much, I think my switch is oriented the wrong way. Right now it is switching left and right instead of up and down. I'm not sure why it didn't fit properly, but it looks like I forced it onto the board the wrong way. I'll pull it off and see if that does it and report back.

Haha, yup. Problem solved. In my defense, the switch didn't fit either way to start with.. not sure if it's the Mouser # I think. It took forever to desolder. I added wire between the board and the switch, I'll mount it in a slightly larger enclosure.

Thanks for the help all, this thing is awesome. Can't wait to explore the possibilities.
