Problems building the Vibrato-Matic III

[svstee]

Came across this:

After looking at a bunch of other Stompboxology and Stompbox Cookbook designs, I decided to go with this one.

The fact that it runs of regular 9v and had a Vero drawn up made it look good, and the soundclips made my mind up. Used this layout:

Anyways, no luck. Not getting any audible vibrato. Based on my voltages I appear to have a working LFO, but nothing is coming of it...

I've gone over the board about three times, no solder bridges, triplechecked components, ect. Where should I be looking?

Thanks!

I think, therefore I bump.

I compared my build to the layout again today. The 10 uf cap conneced to pin 1 of IC1 was in backwards... 
replaced it with a new one in the right way, but I have exactly the same problems. Still not getting any sound through it at all. What else should I be looking at?

One other question. I added the optional Preamp volume pot (1M) using lugs 2 and 3 instead of the 470k resistor, do I need to ground lug 1?

Yes, if wired up as a divider like a typical volume pot.
On second thought, it should work as you have it wired (variable resistor). I think your problem is more than likely elsewhere.
