I am using a matched set of 2N5952s. I would appreciate some tips on trouble shooting my build. Any suggestions will be greatly appreciated!

I’m SO sorry for not responding!  Life got in the way there for a while! I do really appreciate the help and suggestions.

Since I last posted, I have replaced the J201s with matched 5457s and the trim pot to a 300K trimmer.

The result is the same.  Unchanged sound engaged or bypassed.  By the way I did the 2/4 stage mod as we…Read more

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 wa…Read more

With a guitar plugged in, the sound is quite trebly and harsh.  SW1 does in fact add/remove some bass and SW1 has no effect.

The Red Fasel is from Du…Read more

I understand that this isn’t an autowah.  I plan to put this into a standard 1590N1 enclosure and hand-set the wah.  For trouble shooting, I removed the foot switch so at this point it is always on.  There is no change in tone when I turn the pot except when I get to the center of the sweep where I notice a slight change in ba…Read more

I just finished building the v3a MOWAH.  As suggested in the build document, I socketed all of the transistors and the four capacitors.  I was planning to just use a C100K pot so I could set (cock) the WAH so I could put it into a small enclosure and just turn it on and off.

When I tested it, I got the distortion promised by the c…Read more

Thanks very much for the responses!  Now to decide…. tented or lower value!

Thanks again.

Thanks in advance for the help.
