Honey - Special Fuzz

Post by **digi2t** » 15 Mar 2012, 00:53

I came across this fuzz box recently, the Honey Special Fuzz;

It's got me MAJORLY intrigued :icon_eek: :icon_eek: :icon_eek:. I did a search, and it has been discussed here before.

I would love to breadboard/clone this sucker, but I need to find someone out there whos got one.

Anybody out there got one?

Thanks,
Dino

WOW, so many transistors. And what are the inductors for?

I am hoping to see more light shone on this one.

Hi guys.

Just in case someone doesn't follow what's going on over at the "other forum", here's an update. The pedal in action;

The component side;

The trace side with components labeled;

And two trace side shots, for you PCB etchers;

I'll get the wiring diagram up soon.

Cheers,
Dino

Just noticed that there is a resistor missing on the trace side picture.... DOAH!!!

Split the picture in quarters, in the upper left quadrant, smack dab in the middle. There are two bare pads, surrounded by 2 trannies, two 10uF caps, a 1M and 4.7K resistors. There is a 1M resistor missing between the pads here.

I'll update the image asap, I'm working night shifts right now.

Sorry folks

Thanks for the heads up!
Please do. There's some stuff that makes hard earscratching. Knowing the switches connections might help. As well as better demos that clearly show the sonic differences between settings (and less blablabla). While reading the diystomps thread I was rather amazed nobodu even attempted to draw a schem.

If you follow the white wire it goes to a 1uF and a 47k. It does not go to anything else like in the "transparent" picture

. And there's 2 resistors which one would expect to be the same.

Thanks for your astute observation on the cut in the trace Dirk, you're absolutely correct. My bad, I took the picture, and then ran with it. Looking back at the board, there is a cut there. As for the resistors, I checked them again, and they are as in the picture (should change shortly, Photobucket is slow).

I've updated the picture, and here is the wiring;

OK... here's my shot. Screams for some simulations.

Honey Special Fuzz Schematic

The input stage before the filter has a very strong resemblance to the input stage of the Shin-Ei Resleytone (Univibe for most). That, plus the really odd circuit that does the filtering, suggests Fumio Mieda may have had a hand in this one.

only for the record before simulation efforts will begin: R5 = 2k2, R25 = 4k7

Also C1 = 10uF.

Thanks analogguru.

Updated. Thanks gents!

OK, I'm half way to doing a vero of the Ludwig

.

This must be the most complex vero I've ever done, at 13 trannies (not to mention the two 42TL019 audio transformers!). For some bizarre reason, it was almost one of my fastest. I dunno, so don't ask. Here it is;

It's using the same component numbers as Dirk's schematic, and the wire connection numbers as my wiring drawing.

That would make sense because the Resleytone/Univibe etc was originally a Honey design

Sweet Cizus Mother Love Bone

LOL... kinda sorta what crossed my mind when I was done.

Info - I recieved my capacitance/inductance meter today, and I tried out the primary side of a few 42TL019 transformers today. They all came in between 4.3 and 4.9 Henry. They should be suitable stand-in`s as inductors, in place of the TDK`s which I have had no success in finding.

The only thing I`m wondering now is if I should make room for a balancing trimmer between the two trannies in the octave section, a la Super Fuzz. That, and maybe jazzing things up with a fuzz intensity pot.

Still working on the phase rate side of things.

John Lyons · Post by **John Lyons** » 29 Aug 2012, 02:01

The octave/balance is fine when you match the transistors Hfe and use tight tolerance resistors to ground
(22Ks). Some folks like to imbalance that section to get a little less octave so I guess it's up to you whether you
want control over the octave or want it set strong. I don't think it warrants a panel pot but...

No, not a panel pot. It's not worth it, but a trimmer might be "a good thing" if someone is building it with looser tolerances. I would have to rework the layout though, but there is some room for a trimmer beside L1.

Speaking of which, I spotted a couple of errors, which I corrected on the first layout. I had a couple of resistors going the wrong way. Also, I've managed to reduce the size of the board slightly. Here is the layout with the BOM;

Again, still unverified until someone reports a build.

Post by **digi2t** » 07 Sep 2012, 12:24

OK, I had some time, so I did a triple check, and I did spot some errors. They are now corrected, and I would use this to build with. Here is the updated versions, with and without the BOM.

The smallest enclosures I use are the 1590BB style, so this vero is sized to fit widthwise. I figured that way, if another pot, or switch, enters the fray, they'll still be room.

amazing what ya find surfing the flotsam and jetsam of the internet archive...

these two aren't of the honey special fuzz, but hey, in for a dollar....

I wasn't sure if you guys had this one completely traced or not, but there's one on Ebay at the moment:

Just in case you have any additional questions... this guy says he has TWO of these!
