looks cool. supposed to do thru zero flanging and all... hey dino...your ears burning?


do you think this thing may be cool? anybody know anything about them?

[Mark Hammer]

The late lamented Jurgen Haible had replicated it.  You can find all the information, and some sound samples here: http://www.jhaible.de/tau/jh_tau.html

wow,,,,,

me wantee!!!!!!!!!!!!!!!!!!!!

guess i better go look that link over closer...thanks mark!!

holy cow...sounds great!!

Strategy (of this board) has already built one as a pedal. The soundclip he posted is really nice! Check this thread out:

Oufff!!! I took a look at the PCB  . A vero would be hooooge  . Strategy already built one using a PCB, the build report is here in the forum, including a clip with guitar.

Looks like some of the parts would be pretty pricey, and/or tough to find as well, especially the dual FET. I've listened to clips of this baby, and it sounds really nice, but it's not really "blowin' my skirt up" though. Besides, I've listened to a lot of clips and samples of different phasers, and it's not for nothing that people in the know say that anything more than 8 stages is overkill on guitar. 20 stages sounds great on synths, but to my ears, much of the stages get lost with guitar. I just can't hear the difference between 8 stages, and 12 stages on guitar. Thinking about it, I believe it was Mark that led me to somewhat educate myself on the subject, because a while back, I thought that "more is better". In this case, I don't think it is. It's sorta like trying to kill a mouse with a nuclear bomb  .

I'm working on a Gretsh Expandafuzz vero right now, but that's just to tide me over until I get my case for my Ring Stinger clone. The populated boards are sitting there, waiting for their home. Then, I think I'm FINALLY going to tackle the Luddy clone.

"it's in ya, and it's gonna come out"...

all i know is it sounds great to me...didja hear the weird old demo i found? hang on a sec....

http://web.archive.org/web/20040225180212/http://www.keyboardmuseum.org/soundsheet/the%20pipe%20phase.html

it doesn't sound like any other phaser i can think of....

speaking of which...

i figured out what the "mini phase II" is....most likely....(from the couple descriptions, including the one in mass i was trying to find) it's a mutron phaser II.

i can see where peeps that don't know may get confused.

The Tau was the biggest project I ever undertook but one of the most rewarding.

Juergen Haible, guru of synth DIY and fanatic of exotic FX projects, died a few months ago, he was in his mid 40s I think. It's possible that www.bridechamber.com still have the Tau circuit boards.

It's difficult to express exactly the level of loss of this important person in DIY but it's probable his projects will live on through the public domain. I think people are giving some space for his family and friends before taking the endeavor to keep his PCB and DIY projects alive and available

hi bro,
sorry to hear about juergen. that's a true shame, mid 40's is way too young.

the website is gone, so no dice getting a board there.

may have to either bite the bullet and learn to make my own, or do it on vero.

this is one of the coolest phasers i've ever heard...it sounds like the stuff in my head.

If anything, Jurgen became sort of the patron saint of impossiby large projects, demonstrating that they COULD be done, and done well.  Missed, but unlikely to be forgotten by a big bunch of folks.

His website is still up, with all the documents, though I suppose it makes sense to snag the documents posted that you find relevant, since I can't imagine they will be up for years to come, as much as I would hope they would.

[pinkjimiphoton]

i got all the data there i could find associated with juergen's website and diy yesterday.

it's a shame i can't share my archive...i've accumulated about 5 gigs of lost and arcane projects and schematics for things that disappeared years ago.

the web archive has been friendly.

if it was ethical, i'd just up the whole mess to my website so people could take what they want and learn from it.

sadly, this action would end with me being waterboarded by dubya himself in gitmo  most likely.

i hate to see this stuff vanish, too.

Pretty sure Bridechamber has those pcb's?

Oh and @Digit2T:

Tau sounds GREAT on guitar - but not as a phaser, more as a vibe. You can get really weird "extreme" vibrato sounds from it, but not like BBD based chorus vibrato, more like voodoo vibe or univibe but way more intense. The phasing is so extreme you can get pitch bend effects, very Leslie like, very "Pink Floyd live at Pompeii" era sounds.

it wasn't a sound I expected to get from this box at all, kind of a side benefit to the more synth friendly sweeps...

I used the high end IC selection, but later I heard a friend who did one as a modular synth module, and he had used the "budget" IC selection; it sounded amazing as well, so I would say you could still go "budget" and you would NOT be cutting any corners on the sound at all. It would be still totally awesome sounding.

One thing I did not do that I would recommend, is follow the instructions about the shielded cabling. Parts of this circuit do attract noise so use the insulated cable where specified. it's a little bit of an extra pain in wiring.

In that regard also recommend using the headers like Juergen does. I have not used headers on several projects and after wiring, I'd wished I'd used the headers, after all.

Hmmm... I've followed a lot of your work, with much respect as well, so I'll take your word on that. I guess the clips just aren't doing it for me. Then again, the opposite can be true as well, you can hear something really cool on the net, go to the trouble of building it, and then be left completely unimpressed. Been there, done that.

Veroing this would be epic though. I mean, I could do it, but it would need a really big enclosure, and pedal board space is always at a premium. This would be something that I would prefer to have on PCB, but like Jimi says, the link was 404'ing, but up today. It's pricey for the whole kit, but build-wise, I believe the price is justifiable. 

Maybe I'll take a break on the Expandafuzz, and research this some more. I'm gonna have supper now, and mull it over.

[pinkjimiphoton]

dino, enjoy your supper.


didja listen to the clip i found on the web archive?

the thru-zero phased flanging is pretty hip...and it gets into formant areas, too.

i don't think this would be a pedal...more like a rackmount if you did vero i'd think.

as it is, the pcb is double sided and 6x3 " or something like that.

but man...i just have a feeling it would be worth it!

[Strategy]

@digi2t - you've heard my music??? I've (mostly) been able to be on the forum with relative anonymity  glad you have enjoyed.

my early sound clips were done before I had really fully explored the Tau, but I've now done a lot of music that really uses it. At some point I can forward something that shows the thing more in context. Actually my old band FONTANELLE reformed and we recorded an album that is going to come out on the great label Southern Lord. The Tau appears on a lot of organ and rhodes parts on that album and on the rhodes it really awesome through the Tau. On the organ it gets into kind of 1970s sounding phase territory but with the added stages it sounds pretty freaky and futuristic.

@ jimiphoton - so I did build mine as a pedal but that could have been overkill. I would say Rackmount is a good direction. I would like to never again deal with 4PDT wiring or any pedal with stereo outputs. It was the hardest part about the build, I had to have help figuring it out.

I would say this project is DEFINITELY worth it. I really regret I did not get to buy the STORM TIDE FLANGER PCB, another JH project issued shortly before he passed. I'm not a flanging fan but that thing is crazy. All those projects are just really *musical*.

I am working (slowly) on a the Marc Bareille/Papareil MUTRON BIPHASE PCB project, and it will be a desktop or rackmount, no foot bypass. I just don't want to deal with that again!

Strategy

[pinkjimiphoton]

hi strategy,
i'd LOVE to hear this thing on some of your stuff.

i avoided the 4pdt on the clone theory build i did...i just have the stereo output short to ground unless plugged in. otherwise, (since i don't use it in stereo anyways) i'd have used a 3pdt variant of
RG's millenium bypass.

would this even FIT in a stompbox? i'd rather have a pedal than a stomp personally. don't like to have to move rack gear at gigs...prefer stuff in a smaller package.

all the links to the project went down from jurgen's site (at least the ones linked to from the pcb site), but i DID archive all the rest if you or anyone else needs the stormflanger stuff or this project.

i'd really like to build this, but right now i simply can't justify the expense....too broke to boogie.

[digi2t]

OK...

After careful listening, serious consideration, inquiring as to PCB and parts availability, and promising to cut down on my Tim Horton's addiction (OUCH!), I've taken the plunge.

PCB, components, and enclosure, have been ordered. I'm going to use the same type enclosure as my Ring Stinger clone.

Ludwig will have to wait... a tad longer. But not to worry, I ordered an extra enclosure of it as well .

Strategy..... IT'S ALL YOUR FAULT!!!! DAMN YOU!!!! 

[pinkjimiphoton]

nice....no vero this time!!??? lol

can't wait to hear it!!
