Noodling around with some stuff on my bench i decided to throw together a PUSHME PULLME form Toms site http://www.geocities.com/tpe123/folkurban/fuzz/snippets.html second one down..How this thing does it I dont know. The coolest octave up with gain control and a real drive to it :shock: ...Try it if you havent yet......no transformer or diodes a real deal here...Hats off to Tom :D
practice cause time does not stop...

Need to modify your link - take the "..."  off the end.

Sorry force of habit it will work now.. Have you tried this it is the easiest and the best sounding octave I think so far! thanks

Its sorta like the superfuzz octave, the Commander (R.G.) posted an explaination which I'll post here for you to gain better understanding or bewilderment. R.G. is discussing the "octave" trimpot in a superfuzz...

QuoteThat octave circuit is pretty easy to understand. The two transistors sit face to face, the emitters held at a roughly constant voltage by that cap from emitters to ground. The bases are fed out-of-phase by the phase splitter, and the collectors would move in opposite directions except that the Vthevenin on a bipolar is so small. The signal increasing at one base turns that transistor on and the amplified and inverted signal appears at the collector resistor. The other device is turned off by the negative going version of the signal. BJT's turn off faster than they move through the amplifying region, so the on transistor is always the one with the positive going signal. This only works if the two are balanced right at the edge of conduction, equal collector currents, etc. If you unbalance them with the base bias, then one device dominates the signal at the joined collectors. The octave balance control lets you set them so both contribute roughly equally; alternately, it lets you UN balance them for less octave.
There you go. Now you know. I love Tim's stuff.

:oops:  :oops:  :oops: Well It appears there you don't go. puretube points out later in this thread that the PMPY is NOT the same as the Superfuzz :oops:  :oops:  :oops:

I havne't tried that one. But printed it with the idea that I would I'll have to get back on it.

Speak of the circuit snippets site. I built the Tripple Fuzz (not sure if the spelling is intentional) recently and I really liked that one. It has somethhing unique about the fuzz tone. Similar to a fuzz but different.

The Push Me Pull You build for me, was fair, but that could do directly with my equipment. I couldn't use the same transistors either that he specified. They wouldn't make octave tones for me at all. The Tripple Fuzz is a frequency trippler, so yea, the name's intentional. I've built a good half of Tim's circuits so far, and there are an awful lot of great and unique ones on his site. The Octup Blender is rarely mentioned, but it's an awesome circuit. The Psychtar has one of the cleanest up octaves there are.

8-fish: I wouldn`t wanna compare the superfuzz... - in the PMPY:
http://www.geocities.com/tpe123/folkurban/fuzz/pushmepullyou.gif
both base-signals are identical (in-phase);

Thanks tube, I stand corrected.

really neat things can be done with those complementary anti-parallells...

I just breadboarded one, as you seemed quite "stoked" with it ........
THIS THING ROCKS !!
Great octave/Grunge/Fuzz thing going on  :D
Nice one Tim .... again !!

Best "sound" was indeed 2X2N3904 & 1X2N3906  tried a few other
trannies instead of the 3904's.

Wow! How do you find all that stuff? I'm always amazed at the patent you come up with.

 Old patents...too cool !!!
 Thanks for that link 8)

well, if you want to file a patent you have to do a serious research...

if you want to go into the business, you have to know whether you step on anybody`s toes, too...


for my 1st patent, I literally spent weeks in person at the PO;
(that was before they went online, and a non-www Atari was all I had).

Now it`s easy to search for "the Art", when you know which categories to look for, and by cross-searching all the refences cited in the (relevant) files, you soon find yourself browsing through the last century, circuitwise.

(for a while now, I`ve done a heap of download/save/print/read/remember thousands of files - and if I find them easily within my collection...)

Oh man, does THAT take me back!

Jack, RG, Mike Fuller, David Morning, and me all in the same thread.  Those were the days.  I wonder what became of David.  He was a good deal older than the rest of us.  Hope he's still around and kicking.  No, wait, he IS!  Just found him!  http://www.gla.ac.uk:443/stafflist/person.cfm?id=645632  Geez, the web has gotten wonderful these past 13 years.  :icon_biggrin: :icon_biggrin:
