Is this wiring correct?

Can anyone help with the wiring with this circuit? or correct me if I´m wrong. ;)

This is the original PCB layout.

And this is how I did.(I´m getting a loud hum and it doesn´t matter if I´m playing or not.)

Shouldnt that lead thts connected to the "wah pot 3" be connected to the 3rd lug rather than the second?  :)

deadsnake

I though about that too..... but what´s the point of having a pot connected only by the 1st and the 3rd lug? should it be a resistor there instead?

I'm not sure, but I'd wire it the way the diagram says regardless. Someone else can probably drop some wisdom here, though.

I´ve got another little question
-->in this link (http://www.morleypedals.com/pwaes.pdf) you check the schematics for the PCB that I´ve built. There are some minor changes to the schem but most of the rest is untouched.

Near the connected to the R32 1M resistor(which top left oif the schem) there is a simblo that looks like a a batt and it has  + V/2 inside. What does it mean?

  Positive 4.5 volts  (voltage divided by 2)

well then I guess something is wrong with this PCB layout.



If you follow the layout, the 1M resistor is connected in series with a 220uF cap and a 10K res in parallel and ending in GND and not to +.

#7
  It goes thru the 10k on the left side up to the 1N4003 to 9v. Look closer.

ohh yeah that's right. There must be something else there that is causing this. Thanks
