a module a day keeps the doctor away…

oh wait, this was in another context :stuck_out_tongue:
You’re a module machine!

Don’t let them tease you, Dud! You make more modules than a dozen of them combined, fancy wiring doesn’t sound any better!

Put the original Wah-Wah pedal circuit from ElectroSmash on a breadboard today and it actually sounds incredible as a synth filter. Would anybody be interested in a PCB of that?

Absolutely no disrespect to @Dud intended! I’ve made one or two spaghetti sequencers myself.

Getting there!

Looping’s not working yet, but I’ll save that for another day.

Have you seen that ?

This morning the panels for the Ring Mod, the VCDO Additive and the Utility (2 positivizer, 1 glide, 2 attenuverter) were dry :slight_smile:

Now no more wood for panels and i need to buy some standoffs

Yes! Please do that!! And share some sound! :slight_smile:

BTW: is a wah really just a bandpass?

This one?

Or this?

Both do indeed appear to be a resonant bandpass, non voltage controlled. Both use an apparently elusive inductor.

Inductors aren’t elusive, maybe those specific ones, but they’re standard components, you just don’t ever see them in synth circuits. Part of what makes this one fun. Adding an integrated LFO and using dual vactrols to replace the pot today. This one is a collaboration with my dad, who got me into DIY synths.

From the Vox description:

In most classic pedals, there is some component which is often impossible/difficult to find or expensive and it is the one which, of course, gives the best sound or the legendary original tone . In this case the Fasel inductor from the first series
There are several options in the market: The Dunlop Yellow/Red Fasel, TDK, Sabbadius Soul Inductor, Coloursound Inductor, Wipple inductor, SOD inductors, miniature audio transformers and coils from industrial filters.

I don’t think I’ve ever built anything with an inductor, though this module apparently uses 28 of them:

I’ve never believed in “legendary original tone” from magic old parts. It’s just some copper wire wrapped around a lump of iron. The circuit has changed too, the original called for 500mH but we found it sounds best for synthy sounds at 200mH. shrug.

I’ll bet you don’t pay $200 for magic power cords either.

Assembly of my dual Sloth Chaos + simple LFO

Does anyone know other simple resonant bandpass circuits this simple without inductors? I am looking for something to use in a hihat module. It does not need CV…

The YuSynth Fixed Filter Bank uses this:

In some circuits you can use a “gyrator” to replace an inductor:

What’s the circuit for this? Is this based on the ElectricDruid VCDO?
