Not as good as I would have liked but the TZF is just about there - 2 x MN3004, with one clock modulated by an inverted LFO with respect to the other.
if you don't like it can i have it?
very very cool 8)

Me too, me too :icon_lol:
What is it you don't like about it?
BTW, what clock range/delay range do you run the delay lines? Any chance for a schemo? ;)

I think it sounds just great Stephen......
Peace!

Thanks for the nice comments. It's not that I don't like it, it's not as strong as I would like.
I have already posted the schematics on another TZF thread which I can't find at the moment.
Hi Stephen,
It sounds quite good. Apparently you are adding the two delay line paths, which would give you flanging but not TZF. In order to have TZF you need to subtract the output from one delay line from the other (or equivalently, invert one and then add). This should give you the deep, mind blowing cancellation you are after.
I think this is the post with the schematic: http://www.diystompboxes.com/smfforum/index.php?topic=59065.msg461352#msg461352 (http://www.diystompboxes.com/smfforum/index.php?topic=59065.msg461352#msg461352). I must admit, though, that I can't really see what's going on without a little more context. I.e., what's getting mixed at the output? Counterswept delays, or counterswept flangers? I think there's a difference, in that if you lift the dry signal (counterswept delays), it seems that you'll get a convincing symmetrical TZF, whereas if the dry signal is still there (counterswept flangers), maybe it's not so dramatic. Is this what you're getting at, Sebastian?
That said, I like the sound clip. But it doesn't quite seem like the oh-my-god-my-brain-is-turning-inside-out effect that I would expect of TZF.

Thanks Sebastian, I'll have to study the schematic and rewire as necessary, I can easily kill the dry signal.

Yes, counterswept is the word I have been trying to find! You're right in that the "oh-my-god-my-brain-is-turning-inside-out effect" is not there yet. Well, I just played with the controls until I got what appears in the sound sample - it had been gathering dust since about 1990! Feel free to mod the schematic - Paint is good for that!
Stephen,
Looking at the Hyperflanger schems I notice they have everything you need to achieve the TZF. Proper setting would be:
1) Turn down the DRY LEVEL pot to kill entirely the dry signal
2) Turn up the EFFECT BALANCE pot up entirely
3) Toggle the PHASE REVERSE switch back and forth and you should identify which is the TZF position
Sorry but, did a search and couln't find what does TZF means, or should sound like. Could anybody explain :)?
Thanks a lot!
Bye bye
DAC
TZF = Through Zero Flanging...
It sounds like this... http://analogman.com/tzff.htm
Not to say that the pedal being talking about is this pedal.. but this is the only TZF that comes to mind...
The WEM Hyperflanger was in fact a rackmount unit, in one of many piles of papers at home I have a sales flyer.

Thanks Sebastian - buen diiiiiiiiiiiiia, (hotel cleaner in BA!) I think I'm still getting dry signal at the output even with the dry level pot turned off. More anon.
Isn't TZF impossible pedalwise as the copy of the orginal had to come sooner then the original signal?
It's there in the EH Hoax.

the "copy of the original" (the usually modulated delay signal) comes sooner or later than the "original"
(the "dry" signal),
`cause this so-called dry signal is a
fake-original: it is delayed itself (usually fixed),
such that it looks as if the delayed copy is either coming earlier or later...

Very well thought of..........
Is the amount of delay on the dry signal noticable or is it somewhere in the 5ms range?
WhatI also need to try us disconnecting the modulation from one of the BBD clocks.
that`d prolongue the time that both BBDs stay "close" to each other,
which is generally preferable (IMHO),
but my guess is, that what you are missing is being "muffled" by too steep filtering...
(but then again: I might be wrong)
Thanks Ton - filtering..........who needs filtering!!!
Disaster - my wall wart has blown......I think, hopefully not my MN 3004s :icon_rolleyes: :icon_rolleyes:
It's scares me that this thread ended with that post. Is everything okay with it? Any developments?
No, it was OK after all.
