Stage Center Reverb
http://www.generalguitargadgets.com/index.php?option=content&task=view&id=43&Itemid=75

Citaat
Craig Anderton's reverb unit that appeared in the September 1976 Guitar Player magazine. The layout is for a TL074 op amp type pinout instead of the RC4136 op amp originally specified. This circuit is powered by bipolar power supply, I have included a wiring diagram with a charge pump to allow power from a single nine-volt battery without sacrificing any headroom.

I didn't have any succes with getting this thing to work with a RC filter on the power supply as suggested her: http://www.geocities.com/tpe123/folkurban/fuzz/snippets.html
I tried building it without the filter which gave me a loud tone from the VCO at all times. However, if a 1K resistor and a led is connected from +9V to GND before the chip's power pin, it is totally quiet until it's fed with an input. I also added a switch to select a range for the VCO and pot to attenuate the output. This is an easy build if you want a very decent ring modulator-like effect. Could probably use a buffer on the input.
EDIT: it is ALMOST quiet when it is not fed with an input.

THIS PROJECT DOES NOT WORK QUITE RIGHT WITH A REGULAR LM567
this is why specifically asks for an LMC567....big difference
when i tried it with a lm567 it had a lot more bleed. with an lmc567 it had very little.

--------------------------------

LMC567:

http://www.diystompboxes.com/smfforum/index.php?topic=35749.msg252022#msg252022
there is only one LMC567, made by National Semiconductor. The easiest source to obtain one is Digikey. Be sure to specify the 8 pin DIP version

LMC567? Digikey & Jameco. Under a buck at Jameco.

Thing Modulator-stopping oscillations with LM567?

http://www.diystompboxes.com/smfforum/index.php?topic=67470.msg537669#msg537669

I typed "Thing Modulator" and "oscillation" into the  engine here on the site and found....

I got the LM567 to work (in a way, anyway) by using the Thing Modulator schem minus the RC network on the power pin (like the Noise 567), and an LDR in place of the TM's 10k, next to the Frequency pot, which I kept at 100k. To quote Tim E :
"with the desire to make the thing shut up when I'm not playing, I found that using both a LMC567...and a 100k/100uF RC network on the power pin go a long way in suppressing the onboard oscillator..."
reading that, I surmised that the 100k/100uF was there just for the CMOS version and built mine like the Noise 567, without the RC network. I also used the cap values from the Thing Modulator (.1uF all round instead of 10uF and 22nF) ...er...for no real reason except that it would be easier to not put them in all the wrong places. The result is a hilarious collection of dirty ring mod, strange atonal fuzzes and quick decay bong/clang/crashing noises, and the worst/best broken speaker/amp/everything-WTF-noise I've ever produced when hitting more than one string. Oh, did I mention the flat out oscillation at some point of the pot arc? Not that useful, but fun all the same. Yes, it ticks through everything, but if I'm not going to stomp on it, I just pull the (DC) power plug.
Quote
If I understand your question correctly, that "ticking" is the result of the LMC567's internal oscillator spitting out a sloppy rectangle wave. And sloppy modulation. My guess is that there's probably not much that can be done about it. Real ring/balanced modulators often use a triangle or sine wave oscillator for much cleaner sound down into sub audio frequenies. In the case of the Thing Modulator, simplicity dictates the all-in-one chip design utilizing with the internal oscillator.
I know of no mod to counter the effect.

If so, some bleedthrough might be tamed by fiddling with the RC power bypass circuit. The resistor and capacitor I specify are unusually large, which seems to do some voodoo that otherwise might not be done.
Some bleedthrough may be noticable when the circuit is bypassed, as the oscillator runs free in the background, and with true bypass scheme, the raw signal may remain at high impedance. The solution for this problem may be a buffered bypass.

Anyway, I built one a while ago with the plain LM567 chip, and fiddled with it a while to see if I could quieten it down without much luck. Then again, it's not really the ring mod sound I play with - it's the other weirder videogame noises you can get at the other end of the pot's rotation. There's atonal synthy sounds, tones that go down as you go up the fretboard, no note at all (still trying to work out how to use that feature...) and for a bit more noisy fun I put an LDR in line with the pot like the Christian's Noise 567, that the Thing Modulator was derived from. By varying the amount of light hitting the LDR, you can get a wah-like range of tones. Twiddle the knob, fiddle the LDR. Yeeeha

I had a minor problem with the Thing mod, and found I had to mirror the layout I used. I changed the 100k frequenzie pot for a 500k pot, since I liked the ticking, and it did wonders in a feedbackloop.

It works great for me. Double check your wiring and connections. Make sure your using the specified LMC567 chip and not the regular LM567.
Quote
Yes, the LMC567 is absolutely necessary if you want the circuit to behave. That includes a reasonable amount of carrier rejection.
The more common LM567 may not even work with the 100k resistor in series with the power pin, as it's much more of a power hog than the LMC567.
Keep in mind that this is no Blue Ringer. The internal oscillator is fairly limited in range and tone. There's no wet/dry mixing. Carrier rejection is fairly decent considering the simplicity. But any high gain effect after the device will audibly amplify the carrier to possibly annoying levels.

Using LM567

http://www.diystompboxes.com/smfforum/index.php?topic=45164.msg603922#msg603922

I was messing with the Thing Modulator and Noise567 this weekend.  It seems a couple people around have had trouble with this, like I did, and hence was searching older posts.  I found the Worth Ekik site yesterday http://www.geocities.com/worthekik/diy.html--great site! But I figured I would post my findings especially after I read this note there:
"Digikey currently has the "LMC567CN-ND" chip which will work for this, unlike any of the "LM567" variety."   
I bought one of the LM567 from Digi-key, not seeing the C of difference.  I'll order a C variety with my next order from Digi-key Smallbear etc, for curiosity.
But when I was messing with it unaware of this, it was such a simple circuit, I couldn't figure out what I'd done wrong.  I then looked at the noise567 here http://personal.inet.fi/koti/holmberg/images/noise567.jpg.  I noticed that they're the same...LDR vs Pot variable resistors, and cap values not withstandnding.  Output in one is coming from pin 2, the other pin 1, for slightly different sounds (nothing huge considering the weirdness of both).
But on noise567 Pin 4 here is connected right to +9v.  I had even tried stepping the 100k to 4.7k, to no avail. So I connected 9V right to pin 4 (that is, got rid of the 100K resistor in Tim's schematic altogether) and left/added the 100uF cap to ground off of it.  Bingo!  Weirdness.
Deciding if I'm going to build it is a whole 'nother question.  Smiley  But if you can't get you LM567 to work, but it's all you've got, for starters just connect +9v to pin 4,  add that 100uF to ground off pin 4, and you will have instant gratification...rather than waiting for that sole chip to arrive, and the dozens of other parts you didn't need but ordered anyways, because you wanted to make the shipping costs worth it.   icon_mrgreen
Likewise, this may be common info, but expiriment to make the resistance values between pin 5 and 6 larger.  interesting things happen between 1k and 100K, yeah.  But if you like 100K, on the breadboard you can just make the 10K on Tim's schematic a 100K and hence try the 100K-200K range, etc.  In the end, maybe a 250K pot, or a 500K pot, who knows, maybe 1M, but don't be limited where you need not be.  (=
