Title: psychedelic fuzzzzzz!
Post by: doug deeper on July 20, 2009, 06:01:52 PM
so ive tried most of the super buzzy fuzz circuits floating around these parts, and some did it pretty well, others not so much.
this is what ive come up with and settled on for my self, if you're into this type of thing give it a whirl!
just a single volume control on this one, on my personal unit its a trimmer on the board.

I wouldn't mind giving this a go.. looks good. Have any sound clips?

no clips, it sounds like a bee.

Basically an FY-2 without a tone scoop

That'll definitely "buzz", and in a good way !

the real secret is in the 4.7k resistor, super high pass!
the blend is fixed in the "best" spot.
and the pn2222 are kind of important too as they seem to clip a lot differently then most similar transistors.

I like the Pn2222's a lot as well. I also like the plastic case 2N2222 (even better than the metal can ones).

i messed around with the FY-2 sans scoop as per your suggestion before, doug.  it is very cool!.  i think i used it as a jumping off point when i was trying to nail the spirit in the sky tone.  i remember getting pretty close.  i'll have to get back to that one of these days! not to mention giving this a try...

are there any good clips available of the FY-2 or do I need to build one to hear it ?

It demonstrates, in clumsy fashion, the difference, i both tone and volume, between the fuzz with the scoop and with the scoop drastically attenuated.

Thanks Mark!


wow ... really does sound like a bee!
Title: Re: psychedelic fuzzzzzz!
Post by: doug deeper on July 21, 2009, 05:38:23 PM
this one is even buzzier!
give it a whirl.

If it sounds anything like that sound sample, I am going to give it a try.

I built the "os mutantes fuzz" hoping it would sound something like this, but it ended up sounding different (though good in its own way). It is close in some respects, but that supper thin/buzzy bee sound is what I was looking for.

If you push the FY-2 circuit with a boosted input signal, it gets sicker still.  Personally, I'm fnding that I like the unscooped mushy sound.

Note that the "bee-buzz" is largely a byproduct of the post-fuzz toneshaping.  The midscoop carves out the mids, leaving principally the highs and very lows.  Replacing the .001uf treble bypass cap in the midscoop filter with a larger value will let more of the upper mids through for a gnarlier tone.  And of course, anything that filters out less of the signal will necessarily result in greater maximum output level.

Instead of feeding Q2's output through a .0033uf cap then a .001uf cap, Doug's adaptation replaces the .0033uf cap with .0022uf, so you get a taste of the scoop but without the passive loss and with more "bee-buzz".

dont forget that 4.7k resistor!
what you end up with is some serious high pass blended with the out of phase slightly driven low passed signal of the first stage, it really nails the music machine fuzz tone imo.

Right!  Can't see the picture at work, so I forgot about that.

Ahhhh,The Music Machine....
IMO ,the Ultimate fuzztone sound, the sound that i am looking for years and still haven't found, is ......The Music Machine - Trouble.
Just listen to it and tell me what the ?#$? is this....
BTW i have the vinyl ''Bonniwell Music Machine - Ignition". Somewhere on the back it says "Keith Olsen - Bass,Vocals,Fuzz-Designer"!!!
It was 1966-1967.

Nah, you're all wrong.  It's this one, around the 1:50 mark   http://www.youtube.com/watch?v=b6jeQUbovjI

i've got that record as well- not on vinyl though unfortunately.  i need to get more of the early Music Machine stuff. Talk Talk is the jam!

  Hafta say the Holding Company knew well how to use Fuzz in a most gut-wrenching manner, works quite well against a backdrop of solid rythms made from fine artistry/musicianship.
  The Electric Prunes and Strawberry Alarm Clock made some interesting entries, fuzz w/tremolo and other 'oddities' in the mix.

Yeah, I think you win there.  Sam Andrew says here that they used Standell amps and Fuzz Faces: http://www.thepsychedelicguitar.com/andrew.htm

Great job, Doug! Just got done slamming it on the breadboard and was not disappointed..... I could tell you put some effort into  finding the sixties "psych/garage" fuzz sound. I tried mucking about with the 47k that's coming out of Q2 to raise the fuzz volume more, but I then realized the mix is perfect as is. I think I'll save the trimmer and just throw a 100k resistor from output to ground... a true no-knobber!
       Thanks for sharing your efforts, looking forward to what you come up with next.

Hi
Given the feedback paths and various filtering in this, I couldn't "see" what the frequency response would be.  For example, the input cap would have to be filtering a lot of bass, given the low input impedance of the PN2222.  But how much?  So I did a bit of LTSPICE ing and found (if I did this right) that this circuit has a quite large hump in the upper mids (500 to 1kHz).   100 Hz is about 10 dB down and 10kHz is 15 dB down (deep down!). 

Here's the AC analysis.  http://www.aronnelson.com/gallery/main.php?g2_view=core.DownloadItem&g2_itemId=40187&g2_serialNumber=1 (http://www.aronnelson.com/gallery/main.php?g2_view=core.DownloadItem&g2_itemId=40187&g2_serialNumber=1)

Hi
although this is a simple project, I thought I'd knock together a PCB.  Here's a tiny PCB that mounts on the volume pot.
There's what it looks like:

For me it sounds like a boost on the lower frequencies and a fuzz on the high frequencies blended.

Amirite?
