    Alex – a couple things more. Have you THOROUGHLY read the build document and the Mowah Advanced Mod Guide? Between those two documents the Mowah is explained in great detail. There are even some voltage readings in the Mowah Advanced Mod Guide. And at the bottom of the Mowah Advanced Mod Guide, there are a couple of links to facilitate and even greater understanding of this wah circuit.

    Also, to be sure the transistors are all seating snuggly in their respective sockets, try gently “wrinkling” the ends of the leads and re-insert them. Many a builder, including myself, has experienced much un-necessary grief over sloppily fitting components in sockets. Hopefully this image will convey the concept clearly.

    Final update…

    It works!

    I spent more time trying to understand the schematic and how to follow the signal path.  As I mentioned early on, I have no electronics background so with my limited knowledge, I continued testing with the audio probe.  I found one suspect component, the 4.7uf at C7.  I replaced it and lo and behold, I have wah!

    Thanks to you Cybercow for your help and immense patience.  I have learned a lot and I thank you for that as well.

    Now to get it into a box!

    Regards,

    Alex
