An inductor is not a polarized component. It's just one long, thin wire wrapped around a core with two leads. And you are correct. Based on that photo, the top right and bottom left are connected. The other two legs are NOT connected and are used merely to help keep the inductor in place.

The typical wah inductor should measure around 500mH. I've seen wahs with inductor Henry rages from 330mH to 650mH. Because the inductor has only two, non-polarized leads, it shouldn't matter. Just be sure one lead goes on the left side and the other to the right side.

Then you'll likely want to go with the THAT4301 chip which doesn't suffer HF transient laziness. The SSM2166 lets them slip by. Ask most any AI engine this question: "How does the THAT4301 cope with the fast transients at higher frequencies compared to lower frequencies on the guitar compared...

I'm unsure about your question about faster transient response for higher frequencies. What I can make out from the datasheet, I refer to TCP8a on page 5 of the datasheet. The SSM2166 uses a VCA to manage the gain bandwidth, which is virtually flat out to ~10K Hz. The SSM2166 is not extremely...

Of the two I presented, the first is simply a marked up version (with a coupla mod suggestions) of the one from Muzique. The 2nd schematic is Jack Orman's yet-to-be released version 3 which doesn't have the amount of control the 1st one has. Version 3, while using the same chip, seems to be more...

In that case, looking back on my own empirical experiences over time, I had to just build the things that I wanted garner such empirical experiences from. Eventually, I learned how to understand the datasheets by taking the time to scour them, digest what I could and learn how the various...

Nice looking pedal! How did you do the artwork please? Is that UV paint?

Have you seen & examined the SSM2166 Datasheet?

But a tush is good on small hands . . . . 😜

Have you explored the potential of the SSM2166 chip? Jack Orman has done some slick things with this low parts count compressor chip.

I got the "kit" late last fall; October I think.

Still have my Wigginton Voltage Tester from 1976 . . . .

An AI Generated amp demo . . . .

Considering the 'major' portion of SpinCAD Designer's version has been at 0.99 for all these years, one might imagine that a full 1.00 release is eminent. :unsure:

Cool. Thanks DL! Will 1071 be released soon?

There never was an original "pedal" - only the module. The original of the module is more represented by the 1st posting of board #2. But it has mods we made for the actual 'pedal'. And thanks for pointing that out. The 2nd posting was the wrong file. It is now corrected. Here are the original...

Then there's the "Beast With a Thousand JFETs" . . . .

Found an old (May/June 1981) issue of Polyphony with some "Tricks with the SN76477". It's an old, out-of-production sound generator chip with a lot of interesting features/options. The chip is only available from eBay where I found one reliable USA seller who has some NOS of them for $25.00...

Good, clear photos of both sides of the PCB? Schematic?

DL - I've been watching your GitHub site and am quite impressed with how you've madly been going at it. Excellent work! Looking forward to toying with 1070.
