Can mark this SOLVED!

Been playing through it for awhile and it is working great! I would recommend that anyone else that has this or is thinking of building one to use a .0039uF cap in C2. This was the only mod I did and am very happy with results. Thanks for all the suggestions and tips.

OK, I think I have it where I want it. I replaced C2 with a .0039uF (3.9) cap and am now getting a lot better response with the Sensitivity control.

The discussion on Guitar FX also recommends upping the value of C2 to 10nF. Also, R5 should be reduced to 3.9K or 3.6K. Will give this a try. Thanks

When I turn the sensitivity up, does not matter how hard I hit the strings. Was wondering if a different pot value would help.

Here is a link to Guitar FX layouts for the DOD FX25: https://tagboardeffects.blogspot.com/2018/07/dod-fx25-envelope-filter.html Shows the video and also discusses changing some cap and resistor values to take care of the sensitivity control issue.

R10 is 22K, but from a different manufacturer (had 1 left in by stash before I ordered additional ones). Am getting continuity between all of the points you marked. Like I mentioned previously, I am getting good sounds out of this with the sensitivity all the way down. Increasing the sensitivity...

R101 reads 4.3 and 4.65Vdc, and R102 reads 4.5Vdc and 0 on the other side towards IC1.

Could not get rid of the glare when trying to get a picture of the underside. The ground wire was pulled out of my breadboard. R6 and R7 now 4.65Vdc. IC1-3 now reads 4.4Vdc.

Reading 9Vdc on IC1-3 and 9.48Vdc on both sides of R7 and R6.

Sorry about that. Try these out. Am having trouble getting a good picture of the backside of the board. Checked R7 and the solder joint looked good. Also cleaned up a couple of tiny solder blogs off the underside but that did not change any of the voltages.

Decided to build another one of these while I am stuck at home like everyone else. Same issues as with the first build. Double and tripled checked all components etc. Here are a couple of pictures of my build. Have not boxed this one yet but hooked it up to my breadboard to check it out. Am...

I made this pedal for my bass player and he likes the sound he gets from it even though something doesn't seem right. Did not get a chance to take picture before I turned it over to him but I will try to get it back from him to get some pictures. I have built over 50 pedals, including the Mag...

Just completed a Waddle Box build using the PedalBCP board. Got it working right away but am having issues with the controls. If I turn up the sensitivity control up, the signal gets really muddy/bassey. This happens from about 9 o'clock up to all the way and doesn't matter where the Range...

Thanks, will go ahead and order.
