Minnow - Sound like a drum machine?!

[icculus]

Hello! I just finished this build and think something must be wrong. When engaged, it sounds like a sequencer drum machine. Very little guitar signal goes through.

I'm wondering if anyone has seen a demo of this pedal so I can compare it to something? Or if someone who has built it can snap something?

Thank you!

It's not supposed to do that. Look on YouTube for demos of how the FSH-1 or any other auto-wah should sound.
We have a good troubleshooting process here. Part 1 is visual inspection. You, or someone else at your end checks your work to make sure all of the solder joints are good, the board is clean, all of the right parts are installed and oriented correctly. Part 2 is where you post detailed hi-res photos of both sides of your board and we'll check it also. Posting photos does not relieve you of the responsibility of doing Part 1. Part 3 is you telling us anything you did that deviates from the build docs such as modifications or parts substitutions. Feel free to post video of your pedal misbehaving, make sure you show the control settings. We're here to help.

Thanks. I did some tweaking of the trims and got it a bit better. I think this is likely what it is supposed to sound like. I gave a little demo of clean tone, then filter, then S&H. You can hear the clicking when S&H is on and there is no guitar signal. I have a shot of the components. Everything is stock, and I checked all the soldering to the best of my ability. It doesn't sound too far off from the YouTube FSH1 demos I guess. Thanks.

More trimmer adjustment is in order. The S/H is sweeping the filter too far and that's causing the popping.

That sounds pretty neat...
