Wah filter (R.G. Keen)

[Mark Hammer]

same things with Blacks in N-A who took English and re-modelled it to be what we use nowadays in every-day parlance ... call it directed rule breaking if you will - I like to think the exact same psychisms are at play in improvised music making ... I always wondered if/what took place down in Louisianne between the Acadiens (Cajun) and our Black brothers to give rise to what we now call Blues ... IMO there's a big unanswered historical question lying right there

One of the most interesting things I have ever read about the history of popular music was an old book on the history of music in Louisiane.  One of the most arresting images was that of a trend observed in the late 1700's, while the region was still under French control.  It seems there was a section in the opera house in Nouvelle Orleans reserved for freed slaves.  It was not unknown for not-so-freed slaves to sneak out of the plantation in the evening, attend the opera, pretending to be freed slaves, memorize the material,  busk in the streets afterwards, singing arias from high French opera (Rameau, et al), and then sneak back to the plantation before being detected.  Of course, after the territory was captured by the English, the association between simply being French and being upper class did not fade away.  It became the trend to Franci-size one's name to aim for higher social standing.  This is why we have so many musicians from Louisiana with close-but-not-quite-French names.

I did the VCF schematic, It works but the sound produced is really crappy, I want a clean wah sound it gives me a crappy distortioned sound.
I tried to put a 1M voltage divider in front of the circuit (like mentioned in the document) but there's a weird oscillation when it isn't at max.

I'm fed up.  Have you got any other ideas for a box with 4 holes (4controls) , an expression jack and a switch ?

I think it's important to choose the filter section carefully at first - for guitar we're looking for something with lots of bite ... I went through the same thing with my Sample-Glide-Hold explorations ... the first one was using the EMS ladder filter with voltage control (lot's of work, just a low-pass-ish response like this one you built - but cool as a random tone generator), then with a State-Variable with optical control (Mu-Tron III type with f-up Resonance - there's a clip of that one at my site) and also went for Bob Moog's Oberheim/Maestro OTA filter using current control (modded to share driving currents more evenly) ... the two later ones present minor tuning challenges but are workable ...

for new ideas, I thought I had drawn this out before but went and looked and realized I had only ran Spice sims on the idea - namely, of doing what EE's call an op-amp simulation of the basic (non-linear) WAH topology ... I wonder if I should post that ? maybe it's not really what you're looking for - not sure


Mark, that's very interesting - I also read some eye-opening material recently about slavery in the south and the basis for the civil war ... very speculative and unsettling at the same time - maybe there was something too good going down there just like up in Grandmother's Land between the French and the Natives ... hence the basis for Metis culture as it is not widely known

but in relation to what I was talking about, Language/Meaning restrictions, DIY ... have a look here:

interestingo !

I give up wi that. I fed up.

I was thinking make an effect like the Dunlop Q zone (stationary wah) with a femal jack (I wanted put the circuit in a BOss DS2 enclosure and it has a jack "remote") to plug an expression pedal and play with it like a real wah. But that piss me off so I stop  before destroying all

Beside when I tested it, the sound wasn't really like I wanted. So I'll find another circuit to put inside, the anoying thing is to find a control in that circuit to deport in the femal jack to control it with an expression pedal.

Anyway, thanks you so much for you help



I think isn't just a Contry question. We use word with our cultural past or our close environment, I think is not typically Quebecer. You find a little bit the same fact in France or other countries anyway. For instance, I lived to Paris and I moved down to Lyon and I discovered some  expression I've never heard ( and I didn't understand) and some new words too. They use the "patois" proper to that region. You find the the same thing with North (Lille, a movie have be made with this "patois") or south (Marseille) even with the DOM TOM. And even in America I guess (South/North and external contribution).

It must be the same thing with Quebecer i think, they modelled the french language with the passing time to correspond with our culture and our own words meaning.

The expression building, I think , depends  to the past and culture too. Some pure french expressions make any sense for a Canadian and vice verca. You must have a "referencing point" to understand.

But the fact is that sometimes really hard to understand french Quebecer for a french guy, It true. (Something there's subscribes on Canadian TV show ).

Anyway, is a really interessting conversation about English/French/Quebec.

Avec un pays si grande comme le Canada, on a quelques dialectes régionales aussi.  Certainement comprehensible à tout les franco-canadiens et canadiennes, mais avec leurs propres nuances et accents.  En Acadie (principalement au côt est du Nouveau Brunswick, pi des régions de la Nouvelle Écosse et l'île du Prince Edouard), ils parlent "shiac", un espèce de français régionale.
