Ring Stinger Photos

[Gripp]

The holy grail!!

So while we are at it, does anybody have a scan of the manual? It might provide additional useful clues. I've searched around but never found it.

I've been thinking about buying a passive kit from  Ken Stone for a while now, and was going to use a single chip waveform generator such as ICL 8038 for vco. It too has a 14-pin footprint. I'm just thinking out loud in pure excitement here, haven't eyed the pictures closer yet.

BTW: Did you see that in the picture of the ring board from Colin, they have even written down the rejection rate of 60db. In the picture from Soundcollage, it just says OK. I wonder how thight matching one would have to do to achieve this and if it is enough without any additional gating.
Hmm....at least probably no NE570 in there since it has a 16-pin footprint...

Thanks Soundcollage and Collin!!!
Best!

I'm afraid not... quadrafuzz is a multiband distortion and the ring stinger is a diode ring modulator, creating distortion while 4 quadrant multiplying. Both are snazzy though

Oh, now I see what's going on here. Interesting circuit!

Here is the trace side of the transformer/diode board.

Hi Soundcollage!

Great job! I PM-ed you for some additional request for pic's. Basically the more pics the better!

Thanks,

Joep

Been busy with work, but requested photos will be posted soon.

you can see the individual hairs on that bee...  

hair better to see in this TEDDY-BEE pic:


but this one is not a stinger...

I had no idea that was patented.

don`t worry - you can use it - even commercially, now;

but there have been / are people,
that invent(-ed) stuff
that is looked upon as: "everybody knows this"...

:shock:

I think someone reverse-engineered one of these a few months ago over at HC:

- Nice name by the way

Has anyone here played a ring stinger? I've shyed away from ring modulation in the past, with the exception of a couple "intelligent" (tracking) ring mods which are digital in nature. It sounds like this is one insane pedal.

http://forum.musikding.de/attachements/RS_v3.pdf is the first draft of the schemo. I did some simulations in LTSPice and here are the results:

LFO "works"

VCO: freq modulation with either triangle or square LFO "works", but the signal gets stuck at the - in of op amp U9; in PWM mode some signal peaks gets through  the opamp (only in triangle mode, if the trim pot and the freq pot of the VCO are turned near 100%)but the wave shaper does not really seem to convert them;

Audio path should be OK, the gain modulation by the LFO gives reasonable results

Unfortunately, my knowledge on VCOs aproximates zero. Therefore, its pretty unlikely that I would see an probably obvius bug. Would be great if someone with more knowledge could check it.

Since soundcollage kindly sent me some good high resolution pics, resistor values should be OK. Some doubtful values were verified by soundcollage.

Regarding the opamps: from the pics it seems that the lower of the three quad opamps (includes VCO and wave shaper) is slightly different in shape, slightly less broad. But maybe it's just an illusion. Would it make sense to have lets say two TL074 for the main part and a different one for the VCO and the wave shaper.  :?:  :?:

Thanks for your answers

AWESOME WORK!!  Marcus!
Now, i can't say if LFO/VCO looks workable or not,
but i can see U've put a LOT of time into thinking this!
Wish i had time to breadboard the LFO/VCO...  
Sometimes, simulators treat VCOs/LFOs strangely.
Also, it's drawn very small 4 my old eyes.
I tried to print prievew, but comes up blank(?)
For some reason, my printer chopped of the extremeL and extremeR (?)
Looks like a reatively simple circuit... :shock:
The xfmr ring modulator that a guy was selling on ebay used 8 diodes.
He called it, Supposedly, a "Differential Diode Ring Modulator".
Again, AWESOME! revenging; wish i had more time.

All three chips appear to be idential upon close inspection.

[toneman]

All  3 ICs are quad opamps?  right?
Probably TL074 or equiv.
That's what's used in the McMeat.
I figured LT would use descrete VCO/LFO rather than a specialized IC like the 8038 or 2205.
May the clones B with U.
