It's no really typically french to say "Vos doutes sont bien placés" , we say more "vos doutes sont fondés" . Actually the word "placer" doesn't work very well in this sentence.

Which indicates what exactly?

I'm so baffled by most of the world's facility with English and the difficulty I have with even the Latin based languages
let alone the multitudes of other "tongues". I applaud anyone who attempts to learn my convoluted and often contradictory rules of "English as a
second language". Please continue rocking... :icon_cool:

It's true English is easier , this language hasn't all this conjugation or grammar rules. We've a lot of words with different meaning and some words with different meanings depending of the sentence and the idea you want to say , some verbal times that doesn't exist in english, ect....i

Actually I think the expression sctruture of senstences are differente between English type language and Latin lantuage (the simple fact you place adjectives before instead of us , we place it after), I guess it's why english people have some difficulties to learn it (and vice-verca of course, french to english)

Anyway, I think is more usefull to learning english than Spanish/Italian/French . This language open up a lot of doors on the worlds ! It's a great tool to communicate with other people in this Internet aera. See, just for the DIY world all informations you need are in english (I never found sommething about Vibe or Fuzz pedal in french) so even if you don't want you haven't the the choise.

Anyway, that doesn't help me to find out the problem on my wah filter :icon_mrgreen:

Another point, I want to add a gain stage (overdrive) to the wah filter to give it more agressive tone, I'll just put it in front of a TS gain stage but what do you think about a Blend system that will mix wah filter and the "drived" wah filter  ?

I'm sorry I can't offer any intelligent suggestions for your Wah dilema. I've only built Wahs with inductors in 'em. I highly reccomend
obtaining a "Whipple" inductor above anything else on the market. It is slightly sweeter {in terms of harmonic content} than my OEM
"Stack-O-Dimes" inductor and much better than the OEM inductor in my Maestro Boomerang Wah. He sells them for $25 USD but I'm
sure your shipping and duties charges will make the bill twice that amount.
I have a Blackstone boost in front of my Wah that allows me 2 types of Wah inflected crunch that suit my music quite nicely. I've never
heard a Fuzz-Wah or equivalent that really did it correctly. I mean the sum of the parts was a larger trade-off of the individual effects
than I'm willing to settle for in the end. Nes pas? You may find this to be true with an "L" less Wah in the long run. {The Blackstone has
an internal switch to make it buffered or non-buffered which is an important consideration when confronting a typical Wah as well.}

I should have phrased my first post with more clarity...

I meant to ask what, "vos doutes sont fondés" means?! :icon_redface: I recognize the third person plural of "vos" and the verb "sont"
but my Seventh grade Francais occludes further enlightenment.

we're talking "your doubts are well founded" and "your doubts are well placed"

English is a very interesting OS to say the least ... the only reason why "other" people bother learning it is either to make money or to try to understand Anglophones - and vice versa ... not sure if either are working

the distinction between Vos and Votres in French is that typically the plural of Votre is often accompanied with Les, as in Les Votres, otherwise we pronounce Votre and Votres identically and so we can't tell by sound alone which (plural or singular) is being used ... hence the common preference to use Vos in practices like "vos calice de ..."

indeed it would be more correct or appropriate to use fondé as opposed to placé but Mark is, I think, somewhat influenced by Quebecois parlance, where one would on average inately say placé ... like North-American English, Quebecois French has been reduced to an ever tightening set of reflex clichés ...

back to wah's ...

hi Eb7+9 your site is really amazing , I often visit it ! are you french or canadian french maybe ?

to complete the Eb7+9 good explanation, it's a little bit like "this" and "those/these" for you, plural rules but we add a another element , if the thing/personne is female or male (yes even for the thing like a sofa,beer, computer, pedal, pen, solder iron ect... they haven't sex but we do like if they have ).

For the choise of "founded" instead of "placed".

"Founded" (fonder) comes from "fondation"  wehereas "placed" (placer) is more familliar and coresponds more to a place or situation of concret persone/thing (like in the sentence like "the meat is placed on the table". A mistake or a doubt about something is not a really physical thing so isn't really approriate to use "placed".

Who said it's complicated ?   :icon_mrgreen:

Actually, I realize it's really hard to explain language rules and the" word choise".

Also, I realize french is really hard to understand too for english personne, is really different to english structure   :icon_mrgreen:

ben oui, I'm a Coureur de Bois ... stuck doing analogue design in a little cabin in Brutish Calumnia

as the local accupuncturist put it - English is a work language ... It felt sad the way she said it

There's no doubt as far as expressing technical jargon English is sure expedient - in many other ways it's too dismissive ... having half-learnt a few other languages I can say there definitely seems to be a link between what people think (and don't) and the language they operate in ... when two (or more) such cultures live in the same city it's interesting to see what can happen ...

ok, back to the goop ...
salut

fuzzo

ok :) Just "coureur de bois" ? what does it mean ?

Anyway, the circuit still doen't work and I didn't find my mistake  :-\

...And it's even more complicated since ''calice'' can be a verb, an adverb, an adjective or even a proper name...like ''le p'tit Calice d'à coté, je vais lui en calissez une calice en calice!'' :P But it's a bit ''grivois''

Excusez là!

I know, but the pedal i built does not boost...it just increases volume!

Just a little bit  :icon_mrgreen:

but I never heard french using "calisser" .I guess it's a typical French Canadian Word ?

Typicaly used on hot corner in downtown city...but can be eard on unviversity campus too...Not really classy!

Back on the AOP wah, did you resolved your problem? I'm building the Soul kiss (Mike Matthews) and it sound cool. You should give a look at the coloursound inductorless wah...there's a vero in the gallery. Not AOP tough! Take a look at the Parapedal too. There's a layout floating around of the last one too.

Salut!

Nope I didn't. I don't manage to find this fu***** issue. I tried different pot value and Resistor and nothing change. But I can hear the particular wah sound in bass side, but the frequency range doesn't change.


fuzzo

Hi,  a little bump

I still have not found the failure ???

fuzzo

Hi,

If someone has an idea about the issue , let me know.

I'm still looking for the problem that don't find.

checked out the schematics at the top of the thread and both seem to have serious issues ... one needs to be buffered at the input to work right with a guitar and the other ignores conflicting DC conditions at the output of the first op-amp - if that's the one you built you should measure DC voltages in that circuit to confirm ... maybe there's other wah analogues you want to play with - GEO probably has better ones than these two ...

you could always try the Ranger Para-Exciter using a common op-amp instead of the LM4250:

it's a mondo-wah effect that's particularly effective on keyboards - maybe too extreme for gtr
though you'll need a dual pot or a dual optical controller circuit otherwise it's a very easy build

Something I used to follow closely, but lost track of unfortunately, is the "mot de la semaine" service on the CBC Radio show "C'est La Vie".  It would provide typical Canadian-French uses of some fairly common words.  A terrific source of colloquialisms, and a window into the Franco-Canadian heart and mind:  http://www.cbc.ca/cestlavie/words/index.html

C'est facile de conjuger des verbes, un peu plus difficile de savoir si un mot est masculin ou feminin, mais tres difficile d'anticiper le facon donc les Quebecois utilise leurs mots! :icon_wink:

The French connection

Being an old french colony from the 16 th century, we speak more an old fashion french than our French cousin i think.
English expression can be really weird sometimes too. You know how English speakers sometimes say "it's raining cats and dogs"? Well, the French saying makes much more sense: " it's raining ropes/il pleut des cordes". Cats and dogs? Honestly.. who thought of it?! ''It's rainnig frogs'' is even more strange. But i got to agree that ''joual'' speaking can be really hard to understand, even between us, depending on the region you come from.

Anyway, good luck with your wah Fuzzo. Hope you'll resolve your problem.

me too :icon_confused:

I checked the DC voltages :

1=4.73V     8=V+ (9.50V)
2=4.73V     7=4.73V
3=3.01V     6= 4.40V
4= 0V         5= 4.26V

Nothing wrong with me.

Done with a TL072. I used a NE5532, I changed it for a TL072, nothing change.

Quoteyou could always try the Ranger Para-Exciter using a common op-amp instead of the LM4250:

Yeah I could, but I'd like to find the problem with that one. Plus, the circuit is housed in an old Boss box and I don't know if a dual pot can be placed into.

Quote"it's raining cats and dogs"

poor animals, the falling must be hard ;D . Why cats and dogs ? a specific meaning ? 

This circuit is pissing me off, I think I'll give up and try another one. I've found that one :


Simpler and can be more funny. But I think take off the input voltage divder and put a volume control (and "drive" with the overdrive mode) at the end.

no offence intended but I think left-brain (literal) minded folk definitely have a hard time understanding/predicting the non-habitualities of dual brainers ... and that's not just a French/Anglo thing - same thing, quite interestingly, occurs with Gypsies (in Europe) who intentionally delay having they're children "influenced" by THE written word ... those of us who gradually freed ourselves from the shakles of Conservatory training might understand this more easily than rule followers (experts) emprisoned in the realms of obligation and obediance ... my apologies if this sounds offensive

Quebecers by nature typically don't want to be the TOOL of language but more the other way around - which is why language is like plasticine to us "frappé" /// eh ?!

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

some sort of suggestible link between rule-breaking in language and rule-breaking in music finally came recently when I found myself at a Jewish Klezmer concert conversing with the lead Violin guy (an amazing player named Aleksandar Gajic) ... I had to go ask him after the concert if what I heard in their performance - ie., the going between major and minor - is what caused Gypsy music to be frowned upon in some parts of Europe (recall that Sonata's and many classic forms are exclussively major of minor - not mixed) and whether it was in some sense related to our North-American Blues ... what an amazing conversation and a confirmation of my suspicions - I can still feel that parting handshake ...

no it's not a French/Anglo thing ...

I was doing sound at this club the other nite and overheard a Frenchy couple at the door and they were asking if the club had good music and in passing I just rifled off "des fois c'est pas trop pire" as a joke ... turns out the guy was from France and the girl from Quebec ... he just turned to me and said "mais je ne comprends pas" looking all puzzled ... I repeated what I said, again with a puzzled look on his face - I tried to explain the phrase but then paused, looked at the girl who was smiling at me in my vain attempt and realized I couldn't explain it properly ... the joke was on me

it's all so twisted - but not totally untwistable
:icon_wink:

.ps the Q&D filter should work but it will depend on the current-to-resistance qualities of the LED, you may want to try replacing that whole CV works (where the LED ties in to the two caps) by a grounded pot to make life/tuning easier for you ... just an idea
