Building guitarpcb.com D’lay pedal

Hi all

My first post on a forum so I’m not sure if this is in the right spot...


Building a D’lay pedal from guitar pcb.com:

http://www.guitarpcb.com/PDF%20Files/DLay%20v2%20BuildDoc.pdf

Just wondering if the hole with VB on it (next to the 7805 voltage regulator) is supposed to have anything in it?

I’ve seen that some people doing mods to the pedal seem to use that to power another circuit; but in this case I only have the main circuit board (not doing any mods).

Finished it and no sound, just wonder before I go through more troubleshooting, if I would be supposed to have this VB connected to something. It’s not mentioned in the build report above that I can see...

Cheers,
Aidan.

www.guitarpcb.com has a support forum. I see other have asked questions there about the pedal you’re building and received prompt answers. Did you post this question there?
