Just wanted to give you guys a heads up. With the tradition of sharing, I got a bro in ann arbor that has a ring stinger. He's going to be giving me some hi res photos of both top and bottom of the pcb of his ring stinger, and will give me a detailed list of the parts where legible. I was wondering what else would I need to get him to do other than taking closeup photos? I dont know about you but I really want to get a clone of this pedal.

Dude, I DO want a clone too!!! :D
Keep us updated!!! :wink:
Agree with psst!!!
Please keep us updated
also some pics of the pots and wires could help
Let me know if you need help reverse engineering. That;s my favourite part!
Bye,
Joep
I like to clone it too. Pics of the board, copper, wires, pots and maybe some voltages will help.
Great that there is some interest in this. I'll be getting the pics sometime in the next few days. The only problem is I'll have to talk to him about taking voltages, that'll be the hardest part considering he is in a different state as me. I can't wait myself either!
Sometimes the wires are hard to sort out from a photo...knowing which one goes to the middle lug, or more detailed accompanying wiring text...
Hopefully the pot values are marked.
You know, if you really look at the device it wouldn't be that hard to make a workalike.
It's an old-design pattern, with 2 transformers and the diode "ring". In order to get the guitar up there, I'm sure there's some sort of an input boost, probably an op amp. The VCO wouldn't be that difficult, especially if you could live without the sine and sawtooth waveforms. An LFO would be as simple as a schmidt trigger/integrator pattern driving an LED to an LDR to the frequency pot. The timbre control is just a tone knob.

i'm also in for that schem!!. Let me know if i can help.

Listen to Joep, Sirkut, his works are VERY nice.
BTW, Sikut, I would welcome a scanning of the manual, too. :wink:
Actually Joep's response gave me a warm feeling inside!
From the title it sounds like a Ring Mod Fuzz. ?
Well whatever it is it's a cool title, and I too would like to take a look at this one!!!
Thanks, and have a great 'Retro'!!!

you can listen to it here http://www.lovetone.com/ringstinger.html
Count me in as very interested!
Now if I only could get my lazy *** to order some VTL5c3's so I can get get going on the mcmeat...
Best!

I tried to build a classic ring modulators once but with no luck... :(
I really hope this schematic will be online.
Please don't forget to learn anything you can about the transformers!!!
Well, due to certain circumstances, I won't be able to receive those photos sooner than I thought. On the other hand, I'll be taking a trip to Michigan to do a few shows, while I'm there, I'll be personally be taking a load of pictures and measurements of the ring stinger. That will be form the 15th to the 18th. Expect sometime after that some results! Just wanted to keep you posted.
For a ring modulator using a transformer & "diode ring" approach, I believe it matters a GREAT DEAL how well the diodes are matched (depending wha\t you wnat to do with ti musically, it may be that perfect matching is not the best, of course).
You also need to very accurately balance the two "halves" of the transformer output (not easy), otherwise you get heaps of modulation signal through. Foir this and similar reasons I gave up on a transformer-based modulators and designed a switched "balanced" modulator - the Modulatron, mentioned in earlier threads.
Seems if you want diode-ring/transformer ring modulator, it'd much easier to add a noise gate than even try balancing transformers and matching diodes.
But for a quick and dirty build, the passive ring mod is hard to beat. And still has uses, especially if you aren't too finicky about bleedthrough.

Could you get some info? :wink:
Well I looked at it but it was a pain in the ass to even take apart that I decided against it. My bud was very nervous too and that didn't help. Sometime soon I'm just going to buy one and do this myself.
Whacky sounds !!!
YEAHH!!!

:D
Any news?? :D
Any ideas which other circuit comes close (sound- and/or circuitwise)?
Take care,

Not sure if you all missed this thread at all, lots of info about matching diodes. Guitarhacknoise built a passive ring mod, like the ring stinger:

And in terms of matched diodes, someone needs to try all of these:

http://www.nteinc.com/specs/900to999/pdf/nte907.pdf
http://www.intersil.com/data/fn/fn343.pdf
Then we just need matched 1:1 trannies... and a decent amplification system... and a decent carrier nulling system... and a decent LFO... :?

It would appear that the CA3039, our best bet, is outta production. :(

Does anyone else want to join me in the diode array datasheet posting party?
-Colin
MAD1108 samples requested with enough extras to go around....

please please please please please please please
thanks
Thanks for the infos Colin. I doubt that I can help regarding the design of the missing stages.
