I dont know, but it works very well (tried it on my EKO 700 and Stratocaster) Humbucker types seem a bit more pronounced, but it works like a charm nonetheless. Very greenringeresque.
I also used a lpb1 in front to push it a little more ( i dont think its unity by itself)

Interesting! ;)
A demo?
not yet! hopefully tonight!
Thank you! ;)
About the IC, an LM567 will be ok?
I have both LM567 / NE567 and KA567 in my possession. I will test this tonight. I use the 567 a lot. All three types will probably work.
The data sheet for both NE567 and LM567 show supply voltage range of 4.75 - 9V, with nominal 5V.
I know. I must admit I've been using a battery (about 8,1 Volt) . It probably would be a good thing to bring it down a little for powersupply usage. Thanks for your input!

google lm567 hemmo ,you ll find some similar ideas.
those ones you mention are mostly noiseboxes and the ringmod stuff has the '567' noise issue. This is a relatively simple 'clean' octave up (not extremely dirty and noisy). I know I'm probably reinventing something, but this forum is about sharing, right? ;) I will post some samples asap. (BTW. night time for me, Is probably not night time for most of you guys ;)) Im in the +1 Greenwich zone :)

(hope this works, just some short impressions recorded directly into logic)
:D Cool! Sound a bit synthie-like ,but that s the novelty of the circuit.
yes, I'm afraid it won't make it on any Santana coverband pedalboard. my favourite part is when double strings and higher chords get all dissonant ringmodulator like

Love it! May not make it on a Santana cover band pedalboard, but it would for sure make it on a vintage Nintendo cover band board!
Thanks! ;) Don't get me wrong. though... santana at woodstock was pretty cool.. with the amazing rhythm section. that spaced out bongo player. but, you know.. all the middle of the road stuff after that ::)
btw. also try 47nf as an input cap.. might filter out some high frequencies (hope I'm saying this right).. I like it most with the guitartone knob rolled off

Hey, that is actually a very good fuzzy octave. Might try to run it into a heavy fuzz of some BMP stages to get a bit of seppuku space fuzz action (but with a better octave front end)
I will probably need to bring the 9v back to a more safer voltage (5-ish). I dont want to fry the 567, obviously (9volt is already the top). A simple regulator with some power filtering?
Cool and weird fuzzy sound! ;)
Even with a 2-resistor voltage divider and filter caps, this still has to be the lowest parts count octaver!
Or a small resistor and a zener. (7v6 ?)
Sounds a little like a ring modulator. Cool.
I was trying for a 7805 solution with filtering caps, but you guys can easily beat me with a lower partcount :)
Thanks!.. no I'm gonna wait for someone to mod the **** out of it and make it way cooler

Not my tonal cup of tea, but for only 4 parts, I am mucho impressed. Tip o' the hat, my friend.
It's more of a synth sound than a guitar sound, to me. But I like it!
Has anyone build it yet? I know there's not a lot to verify, but still. I also need to make a new layout with a voltage regulator (perfect voltage for the chip is between 4,5 and 9 volts) if anyone wants to chip in with a stable low part solution, be my guest. I will probably work on it this weekend.
about voltage dividers.. bare with me.. would this work for this circuit? What kind of power filtering would this need?

Hey FuZZZZzzz.
Nearly let this one slip by without noticing.
Still got a couple of 567s
Definitely on the build list. Still annoying my bandmates with the Thulsa Doom, Ha ha ha.
It wont be so impressive on bass I'm afraid.. time to get out the sixstring ;)

I would increase the resistors a bit. Now there is 250 ohms between 9V and GND, meaning that there will be 0.324 Watts on that resistor.. So it'll get hot ,and if you use 1/4 Watt resistors it'll burn out.
Also, check the current requirement of the 567. If you make R1 too big it will get too little current.
I'd still go for the zener option..
EDIT: It needs max. 13mA so the max R1 you can use is 9V / 0.013 = 692 Ohms. (680 is a nice close value)
This would give a divider of 680 / 2k7
thank you arph. still a lot to learn. what would be the big advantage with the zener option over this?
It'll keep the input voltage to the 567 constant with a varying supply. (as long as the supply is higher than the zener value.) With a divider, the divided voltage follows the input voltage.
cool, thanks! will try both

To limit current through the diode I believe. I once tried it without and things got heated ;D
It depends on the current draw - i suppose it will be 5-15mA. In that case use a common diode or even 20mA LED in series with the DC input. No resistor or even a voltage divider is necessary. The diode/LED will drop the voltage 1-2V and it will work as a polarity protection at the same time..
Thanks for the thumbs up! ;D Looking from the music in you signature..you definitely have to build one yourself as well ;)

Just built this today. I added a little mod of my own - a 100k linear pot between pin 5 and 8. Lets you control the amount of fizz and bittcrushy-ness, although the control knob is not especially dramatic, it does make enough of a difference to be worthwhile if you are looking for a way to shape the tone. For those who are messing with this circuit (thanks for dreaming this up, Fuzzzzzzzz) have you had any luck improving the sustain - since notes fart out very quickly? Also curious to know if anyone has actually fried their chip with the 9v. Maybe worth it to put a small resistor between the battery and the circuit?

Hi guys! thanks for verifying. and thanks for the mod!!.. worth a try. :) Im on holiday in China the coming 3 weeks.. so will only check now and then and will not be able to try anything. will read again now and then. also, try changing cap to 47f (less fizzle)
ow.. i'v burned a few 567 with a 9 v adapter.. so yes we need a voltage regulator.. see the info on the previous page ;) and lets see those photos!!!
try putting a booster in front for more sustain. I used a lpb1 1 pedal in front.. also gives you a warmer sounding fuzzy result. I like this one with the notes fading quickly.. more NES sounding ;)

hello - and thanks for the easy layout!
is that a shared hole 9V and C1 ground?
thanks
Perhaps just a buffer in front could achieve sustain?
AFAIK the circuit has low input impedance.
sick octave synthy stuff..nice one fuzzzzzzz...
have you tried a dirt in front/behind it?...could be cool.. :icon_cool:
Nice. Actually more musical than I expected, and sometimes makes better bell tones than more complex circuits can manage.
If you must add something to drop the supply volts - if it takes less than 10mA, you could just use a standard LED in series and it also gives you a power indicator?
I just built a circuit around this chip, and I'm getting a fuzzy sound but nothing like the great sounds in the demos. More like clean guitar with some fizz in the background. A few questions:
1. I'm using an LM567. Which pin is supposed to be the output? From the layout it appears that pin 8 is the output, but I got virtually no sound from that so I switched it to pin 2 as per the Thing Modulator and the Beavis Audio versions.
2. I used a 78L05 regulator to power the chip, and it's connected directly to pin 4. Is a series resistor required? Should the chip be powered closer to 9V to get the right sound?
3. I sandwiched the chip between a TL072 non-inv gain stage (pre) and an MPF102 buffer (post) because I wanted some pre-boost and I wasn't sure what the output impedance of the LM567 was. Is the chip expected to be loaded down by the guitar? I figured not since some people have mentioned using a booster on the front end, but maybe it is?
What do you mean? Im a bit lost 😁

sorry bout that, does the 9v input share a hole with C2 on row E ?
i guess I can just add a row oon each end lol
Breadboarding this kind of easy lay-outs Will save you kots of trouble.
1. There must be something wrong with your build. Output in this build is 8. Other designs might use other pins. It has been verified like this.
2. I have not checked this myself. Please check some voltage divider ideas on page1 and 2 of this thread
3. I think a schematic would be nice to see what you mean.

'its part bit crusher & part fuzz ..its unique and in a mini 1590g so I had to leave out the bypass switch. you will have to loop it or just have fun with it.'
no it isnt.. yes its unique, because its mine..
I know this shit happens when you post your ideas on a diy forum, but still would be nice if this person thanked me for it, before selling it under his own brand.
Sheesh! That listing is bizarre. Is it even real? And what about the description? "Doesn't work, sound like crap" and Make:"Junk"? Has the listing been hacked?
the guy just changed his advertisement after reading this :-\ reverb.com is a genuine website, but apparantly he could not delete his ad after a sales and just changed it.
it looked very different a couple of hours ago.. He just changed it to avoid confrontation. But why? a simple post in this thread would have been enough. I dont mind people building stuff, but he could at least posted his build and experiences and asked if it was ok to sell a build he was probably not using himself anymore
people like this just take the fun out of posting here

I dont know what you mean with Our own "LiSoGeo", but the original (Reverb) sales link said 25 dollar or so. The original ad was only changed after I posted this thread about it. The poster of the original Reverb.com ad then ridiculed its own ad by changing the photos, text and price, so he or she did not have to take responsibility I guess. If its also a DIY Stompboxes member.. then it's even a sadder story.. go design and sell your own stuff!
Less people will post here if their ideas are just being copied and sold by people who take credit for someone else's work.
The seller's handle is in this very thread.... :-\
So it appears that it IS sadder than you thought.
Hey guys, I'm just wondering about where this thread has gone, hmm, a 4-component circuit built & sold for $25... I sorta understand both sides? Would it have been better if he had said "as posted by FUZZZZzzzz on DIYStompoxes Forums" in his ad? Or if he had've personally contacted you first for your "ok"? (Would you have said "ok"?) Or, you were expecting royalties...? I dunno, I know circuits are unpatented & uncopyrighted & stuff, and that it's more the "ethics" of the situation... But I think of things like the bazz fuss which gets built (& sold (for cheap)) quite a lot, also many other circuits which are really just "variations on the theme" of some other circuit... I dunno where I'm going with this... I guess I'm just thinking, maybe (?)... "so what?" [OK, blast me now ha ha! :icon_mrgreen:]
thank you for the input monksanto. its indeed a grey area. ill just leave it with that. im going to work on this pee eight for a little more and re design it a bit. have you build this pedal? have you tried the 100k pot mod?

as you were...
I just had a listen, Rob. I didn't think your drumming was that bad, mate! ;D
hey man..I made the thing, didnt like it. I sold it as pee 8 octave fuzz hand made by me ,meaning I put it together myself . I never claimed I invented the thing. I never sold it. I pulled the ad and refunded the money if you look hard enough sherlok and why not just mind your own business and no harm was done but you had to resurrect this instead of letting it die ..drama queen you are ..so dont you chill out man and take your own advice . I thought people posted stuff on here for us to use and try out . I never "stole" anything. I am using the old 1960's freeweb domain crap floating around like everyone else . orange squeeze, anderton tube sound, colorsound one knob fuzz

the astronout seems to want to make drama out of this and wont let it die ..
This is a really cool little circuit FUZZ, a lot of potential! I was working on a fuzz/tonebender variant which I have shelved for now but the last incarnation ended up using a portion of Escobedo's push me pull you to get a sort of octave texture. Should maybe have tried this one instead! I will have to breadboard it and have a play when I get some time.
As for selling the circuit, it would be different if it was something finished, boxed and been around for a while like the hundreds of muffs or tube screamers. I suppose it's less about the legalities and more about ethics and respect but that's only my two cents. Really great of you to share anyhow it is much appreciated and a really cool idea.
Ok, i,ll just say this again, ...i never refered to you in anyway whatsoever ...

LightSoundGeometry is probably just a cool guy like everyone else here, but maybe he's got a feeling like we're all teaming up on him. I'm not angry with anyone here. Just a big misunderstanding. I was the one with the original post, but that was before I even knew who was behind it. So maybe my post was a bit of over reacting. Sorry guys for all the trouble. The best thing about this forum is the friendly people with good advice sharing their knowledge. I've learned a lot here and really want to continue doing so.
