Would anyone be willing to do up a Vero layout for the attached schematic? I've searched and searched but couldn't find a verified Vero layout anywhere.

Thanks!

It it similar to this

Similar but not quite the same. The schematic I posted is only a lpf and designed for a 9v power supply.

The Eric Archer VCF is pretty cool. It has a blend control, the resonance pot takes it all the way up to self oscillation and you can use an expression pedal to make it into the world's squelchiest wah pedal. I breadboarded it and shot a video a while back.

Nice! I was looking at that build as well. The perf layout is a bit intimidating with the wiring, but it may be worth a shot. It's funny, I've found many variations on the ms 20 lpf, but no verified vero layouts.

Wow, great video! I'm building one of these when I get some spare time. How did you convert it for expression pedal use, nocentelli? I couldn't see it in the pdf.

[Ciaran Haslett]

It just replaces the Freq pot in the top schematic.

Lug 1 to GND
Lug 2 to the 100Ks
Lug 3 to 9V

[Silver Blues]

Hmm and you  could make this envelope-driven in the same fashion couldn't you?

[Addy Bart]

Hi Ciaran. Cheers for answering. Just to clarify what goes where on the stereo jack for the expression pedal... would it be wired up like this?

Lug 1 to GND: sleeve
Lug 2 to the 100k: tip
Lug 3 to 9V: ring

Yes, that is how the pot in my EV-5 expression pedal is wired, I assume it is standard for most expression pedals.

I think you're correct. Unfortunately for me the Line6 EX-1 uses a mono jack so I guess I'll need to look for an old wah enclosure to build this inside or just buy a new expression pedal.

[Ciaran Haslett]

If you were feeling adventurous you could mod the line 6 pedal to include a switching stereo jack socket and wire the pot to this.  TRS when a jack is inserted...TS when there isn't.  £0.70 mod and job done!

[Addy Bart]

Great idea! I'll try that. Cheers. :-)
