Hi

Just finished the Zombie Chorus, but was unlucky with this layout:
http://www.aronnelson.com/gallery/main.php/v/Xaviers-shrine-of-noise/Layouts/Zombie_001.gif.html

After checking it with the shematic I found some mistakes:
- there are two ground lines: the connection is missing
- pin 3 and 4 (IC2: MN3007) are grounded on the layout, but the shematic shows, that pin 4 and 5 must be groundet
- there is no connection between the input of the MN3007 (pin 3) and the output of the Oamp (pin 1)

I visualitzed the mistakes on following layout:

But it's still not working. Im getting a bypassed guitar signal with no effect. This is the only layout for breadboards I've found and I want to fix it.

Here is a picture of my build:

And here the shematic:

Doest somebody build it with this layout and get it working ? Can somebody find more mistakes in the layout ?

LiquidSteel

I found the last mistake !
- pin 14 of IC1 have to be connected with V+

Now everything works great. So be carefull if you use this layout and attend the mistakes !
