Any news on this? I've emailed Bridechamber but no reply... not sure I'm using the right address.

Cheers!
thumbs up

Yea Scott is a busy guy, he'll probably get back to you soon. I'm waiting for the dual teezer too but I bet it's gonna be a while yet:(
vav
I need one of these.
petejm
Okay, no worries, looking forward to this one!
headcleaner
not heard of this before!! - hyped for it though, i mean who can afford a zero right? i was gonna buy a motm kit and shove it inside my case to make it go euro but an actual euro kit would be wwwaaaaayyyy better.......

an 2 in one unit....awesome.

bring the bells!!
numan7
thumbs up awesome, awesome!!

any pictures?

cheers,

petejm
I don't think so, just MOTM panel design (and sound samples!!) at bridechamber.com...

Yea, def gonna be good. No wave morph like the zero but two through zero osc aint bad a tall.
Meat Parade
Whats the price range for this? Is it safe to say this would be a good alternative to get thru zero in your case without spending 1300$ on a Cyndustries Zeroscillator?

Isn't Elby or someone else working on a dual Teezer Euro module?

doepfer is working on a thru zero osc, not a teezer but maybe this is what youre thinking of
Veqtor
Considering the fact that there has been no news on the doepfer thru zero osc for ages... I think it's safe to say that it has entered some kind of limbo doepfer vaporware dimension.

Really looking forward to the bridechamber dual teezer!

is there any more info about the dual teezer other than coming in 2011?
petejm
Has anyone any news on this one, is it still happening?

Thanks

Whoah, so 50(? IIRC, there was a picture of a pile of them) nearly completed modules are getting scrapped?

waah

I was hoping to pair a dual teezer WITH the rubicon

damn, thats a bummer.
maybe you can find another actual Euro producer to do it?

Yeah, that is a bummer, i was really looking forward to building this.

I've just heard from Scott that he has a batch of dual Euro Teezers assembled and another getting close. The price is not exactly fixed, but I'm pretty sure it is going to be competitive.

Ian
petejm
Huh, a little over a week ago this wasn't happening & now one batch has been assembled & another almost ready??? Am I missing something here?

I'm not complaining, just confused! hmmm.....
softpieces
Very interested in this.
mojopin
oh shit... dual teezers...rubicon... and zeroscillators in stock at AH

let's just hope it isn't five inches deep!

Goddamn, you had me worried, Ian. Because I do want to check out one of Scott's Dual-Tezzers. I'll have to bug him to bring one to a 'Wiggler meet here in town.

Thanks for the heads up. thumbs up

There's a preorder page up now. $650, so a decent discount compared to two Rubicons. Not skiffable, 4.1in deep.

I think it's certainly effective - given how I believe the boards had to be mounted. Not flashy - sure, but effective.

I don't understand the appeal seriously, i just don't get it

It looks like two teezers, built and placed under the same front panel... why not just build two single units? why not make use of the wasted space that is the giant strip through the middle, and replace the unneeded writing for some features that justify two teezers in the same unit?

A ring mod?
A mixer?
Anything?

Don't get me wrong, two is better than one... but is there same feature that's not evident from the pics that I'm missing, that justifies a single dual panel, instead of two single panels?

I'm going to guess that the PCB is so wide that standing it upright (to do a single-Tezzer) wasn't feasible. So with the current design, the only option was to mount the PCB width-wise and perpendicular to the panel. That said - the only way to reasonably consume that much HP would be to do a dual unit (at that point).

ah kk, thanks for clearing that up.

I think it would be great if the panel had some features like summed outputs and perhaps normalized inputs for the LIN & Exp FM between osc 1 and 2, with knobs for offset or polarity (so a modulation source could be applied to osc 1, and slightly offset or inverted then sent to osc 2 if nothing else is plugged in). There seems to be plenty of room on the panel which could be utilized still.
Drumdrumdrumdrum
I thought, from the bell demo, that it has got a ringmods? By the look of the front panel it seems not. Why not? seriously, i just don't get it

Yes, I'm assuming (though I may be wrong) that these are using the same PCB as the 5U. Since there's now some commercial imperative to get these on the market it was probably quicker to produce a dual unit with those PCBs rather than design, lay out and debug a specific Euro PCB. Once again, just conjecture, and not in any way intended to be a criticism - I have some very fine dual/multi Euro modules that use CGS boards and panels from Clarke for example.

I believe that the bells demo was intended to demonstrate that Thru-Zero is capable of producing very realistic sounds of this type simply using FM.

Cheers

Those are some FM bells, yo. And speaking of that... as an FM-oriented oscillator, a dual module makes a lot of sense. May well have to do with the PCB size too, although the originals were too tall to clear the rails in anything other than a 'shelf' configuration which is really hacky IMO. I'd hope they were trimmed down for parallel mounting.
softpieces
This looks great. Like others have said, a mix bus for internal routing (with manual and cv control of the routed wave's amplitude) would take this to the next level.
Drumdrumdrumdrum
OK. Wow!

Appears this might be the case, the Bridechamber website warns these are not skiff-friendly at 4.1". Which I do believe looks very close to the width of the 5U PCB. The pots on this panel don't quite match the PCB-mounted pots on those PCBs though, so it could still be a different PCB.

So: Are the dual units somehow linked together?

And: Is the missing pulse output relevant or not? seriously, i just don't get it

sonicwarrior wrote:

I doubt that they're linked. It's intended for dynamic FM, but without forcing the user to use a particular VCA for depth.

There are no pulse outputs in the design. That can be done very easily with external comparators. I'm going to build a 5-pulser to go with mine.
sonicwarrior
thermionicjunky wrote:

It has mini jacks, so normalizations are possible. Normalizations can be broken so no forcing the user to whatsoever. Just allowing the two units to interact without patchcords like many other units do.

So what size are the PCBs for sale on bridechamber?

One of my cabinets is deep, so I can do it.
sonicwarrior
The regular non Eurorack PCB is 143 mm x 115 mm. At least that's what I measured on mine. You can mount the pots on the PCB which means the depth can be ca. 115 mm.
It's not as long as a standard Ken Stone PCB.

It looks like there are 2x 4.1" boards, however, if they sell the boards separately, which I'm really hoping they do, you could parallel mount them to the panel. If you pack it right, you should be able to get it within 2"? I'm just kind of guessing with my fingers. I don't know off hand how deep a skiff is, but you might be able to pull that off. hmmm.....

Oh, and if you can, 4.1" is 20.5hp so you can easily get it behind a 24hp panel which gives you breathing room on the sides. This is just what I've speculated from Scott's site (which doesn't give a lot more detail...).

*Edit: Okay, so it looks like the reason why there are two boards is the module is a dual d'oh!. So you should be able to make a skiff friendly version of this, but it will take some wiring.

Hmmn not sure, here's the pcbs that are currently being sold:

Board Size 4.625” x 5.75” which is just for one oscillator.

I can't speak to the Teezer per se, but the Rubicon definitely has a few extra things to adjust for TZFM over and above a typical VCO, so I wouldn't be surprised.

Teezer has 7 or 8 trimpots per oscillator which suggests it will require either some decent instructions or a good understanding of the circuit to pull off well!

When I asked Scott about diy options, this is what he said:

"Euro Teezer -- first one is done, testing and trimming. Could do a kit, but it's a big fella and the docs aren't very supportive. If you're interested I can do one. (EDITED out pricing that he hasn't revealed yet) -- everything is flying wires!!!!!!"

So it sounds like a tricky build.

That's more or less what I measured. Just not in the metric system.

I'm counting 6 on my already stuffed PCB. There is an optional trimmer that I didn't stuff.

Juxwl wrote:

I can't second that. It's not thaaat big and the docs have been OK so far. There is stuff far worse out there.
Norman_Phay
Yeah I concur, I'm about 3/4 thru stuffing my teezer PCB and it's not that big a stuffing job, at least compared to most of the JH boards I've assembled and the docs are fine! Everything you need is in there.
frijitz
Just a couple of quick notes on the dual Euro Teezer.

The board is a chopped down version of the original, with board-mounted controls removed, a Euro PS connector added and an additional waveshape trimmer added. The boards are mounted back-to-back perpendicular to the panel to allow access to both sets of trimmers.

All but one of the setup adjustments for the Teezer are easy. They are as follows:
Tuning -- 1V/Oct and HF tracking (standard).
Sine wave -- Offset and shape (standard).
Tri wave -- Offset (standard).
Saw/Tri symmetry -- Two adjustments, easily made while observing the Tri.
Threshold -- Tweaks the core to equalize the up and down ramps. Addresses a minor issue with the core syncing to the modulation source under special conditions. Optional, as the issue is almost never problematic.

Our intent is to mainly sell this as a completed module. A limited number of kits may be made available. Please contact Scott directly if you are a current customer and interested in this option.

Nothing like digging up an old thread to announce something newly available smile

After synthCube acquired Bridechamber, it took some time for all of the original bridechamber stock to make its way into our shop. We recently uncovered a box and to our surprise we found the original run of these ian fritz dual teezer VCO PCBs, panels and custom mounting brackets. Only 25 sets were made.

They are available now, on a limited run basis. Feel free to use this thread for comments, questions, build examples, troubleshooting etc. The kits are available in beta format- while we have a couple kits out to trusted builders for verification and fine tuning, the kits as offered are based on the original Ian Fritz and Bridechamber documentation.

I recently purchased the Dual Teezer Eurorack boards/panel/bracket from Synthcube. I'm working on a Mouser Project for it. Paying a quarter for a common cap seems a bit high, but the 0.22 uF C0G caps for $1+ each is really killing me. This is particularly the case since I need 24 of them.

So ... my question is "how important is the C0G spec in this project"? Can I get a cheaper cap without sacrificing, say, stability?

Ian, love your modules. Can you please educate me on C0G? Thanks in advance!

The version of the docs I have says plastic or ceramic for the .22’s. Plastic can be PE/mylar. Ceramic would just be inexpensive discs.

No pictures d'oh! oops

I'm sorry Ian, but that problem and solution may have had a bit too much assistance from Hamms. beer! oops Just popped the module out, immediately saw the problem that had been "fixed" before. The PCB is perfect, sorry for the bad information! I've removed it from the original post.

Ah, that’s the problem—you need a better brand of beer lol

That design is so old and has had such an unfortunate history, I’ve lost track of all the different versions and corrections. Glad to hear you cleared up this issue.

Since I had to research this, I though I'd add a note. The Sync level pot is connected to the J2 connector as follows:
viewed from the rear, with lugs on the bottom,

rightmost lug (CCW from front panel perspective) connects to ground
middle lug (output) connects to S lev 2
leftmost lug (CW from front panel perspective) connects to S lev 1
