So after being inspired by cortexturizers great sounding pharaoh I wanted to give one a go. I built it up on a mudbunny and also borrowed cortext's "pre-gain" mod and placed a 10k pot at R13. I labeled it "attack" on the pedal. After trying TONS of transistor combos I ended up wth a BC550 in Q1 and 2n5089s in Q2-Q4. I tried some lower gain transistors but they all sounded fizzy and starved in this circuit.
Did another etched graphic and like how it turned out pretty well. The sides are still powdercoat almond.
Anyway, I am digging it so far and have found atleast a few very usable settings in my initial go. See the sound demo below as well for 3 unique flavors.

Totally sweet build. That demo is fantastic. Is that an e-bow you used to make those violin like arpeggio sounds? That is so cool.

Yes it is. I don't use that crazy little thing that often but it is fun once in a while. This fuzz is actually the first one that sounds ok with an e-bow.
Hey Pryde that is awsome I love the faux cello sound...what would J. S Bach have thought!!!
Great build and the soundtrack is just fantastic :) I hate you really,but in a nice way.
Great work that seems to get better and better.
Lovin it 8)
Mike
Bravo. I really love this.
great work jeff
Great demo, especially the first part, and the enclosure is awesome. How do you etch the top of a powdercoated enclosure, do you just have it powdercoated, sand the top and etch it?
Thanks everyone.
Yes the enclosure started as a full powdercoated one from PPP. Then the face of it met the belt sander ;D. I did not have any plain enclosures left so I had to improv. I think it would have looked even slicker starting with a black enclosure.
Pretty sweet etching and the demo is pretty smooth too! The ebow sounds so nice!
What's different on the mudbunny to make it a pharaoh? what mudbunny variant did you use as the base? I haven't found a schem for the pharaoh so I'm curious. I was going to build it from the vero cortexturizer referenced but I have a mudbunny coming so maybe that would be the easier route.
Awesome awesome pedal, great look, great sound!
I'm also keen to build one on a mudbunny board and wonder as well what schematic you used for it and about the pre gain mod?!?
I found this when I searched around (on the Kit Rae website). Is that similar to what you did?
Slick build and cool demo!
Cooder, that Kit Rae schem has a few errors. All those coupling caps should be 470n.
It doesn't sound bad with 47n, but the 'correct' value is definitely 470n.
See the attachment for values to use on the mudbunny. I crossed referenced with a known verified schematic from FSB and rechecked against sabrotones vero so I "think" its correct.
The "pre-gain/attack mod" is suggested by cortexturizer. Just place a 10kB pot in R13 on the mudbunny. It makes the resistance variable between the 2nd and 3rd gain stage (normally a 6.2k fixed resistor). I think the effect is minimal when using silicon clipping but it seams to produce a more pronounced pick attack with the germ or lifted clip options. Still need to play with it more though.
Great etch mate, love how the scarab's holding the LED, first time i think i've seen a powdercoated/etched enclosure, sweet demo too, Matt.
Thats fun-tastic.
I love every aspect of it - starting from the enclosure and graphics, getting on with the build itself, finishing with this great demo!
respect!
Great, thanks for posting those parts value for Mudbunny board! Awesome stuff, agree to all the good comments...!
Incredibly well done my friend!
It just so happens that I am in a bus heading towards Greece and we got stuck at the border so I decided to take a look at the forum and of course there were so much beautiful builds waiting for me to admire them.
I find it a little strange that you have been experiencing a slight pre gain effect by the r13 turned to pot mod,it seemed to make hell of adifference even in Si mode with my builds...aaaah what the hell every one of these bad boys is different thats why you just...gotta...build...some more.
the amount of dist/fizz really had much more to do with the type of other components used rather than transistors,at last thats what i've found.
regards frienda see ya in ten days or so hehe
Let the germanium flow.
Flow river wide,
Ocean deep.
there's a fuzzed out haiku for you guys, ciao!

Uh... Haiku's are 5-7-5... that's a nice poem though.

We should make a poetry topic where we would praise fuzz and germanium. The Centaur as well. Maybe smt in the lines of
On a Saturday evening hour
I found her shivering hand
the rehearsal went well
so I gave her my Centaur.
It melt her hand like germanium sand
the NOS diodes were just too much.
I am sorry guys,this waiting at the border is killing me.
pryde sorry man for hijacking the topic i adore this build of yours,now we are waiting to see what will ghost of thoad bring us! Really anxious to see
No problem. I can dig poetry also :)
When you get a chance listen to the demo, maybe with some headphones. I would like to hear your thoughts on how it sounds (as compared with yours).
Also, I may need to do more looking into the R13 mod as mine produces pretty subtle changes overall. I am hoping to get more of that scratchy-pick attack sound out of it.
Pryde - got mine almost done. How did you wire the highs pot? Does it come off r19? And if so does lugs 1 and 2 get connected to each other? Thx
Pryde, I loved the drone part of the demo! Was that just the muff?

Oh, is THAT what they call it? Kinky ;)
@johntoadsghost:
Yes R19 is highs pot, link lugs 1 and 2 as you said.
Are you going to try the "pregain/attack" mod? If so, same thing to R13 but use a 10kb pot.
@alanp:
the drone section was just the fuzz with a bit of delay (zero point mini) and an E-bow to get the violin and cello like sounds. I don't use that Ebow very often so I kinda suck at it but some people can use that thing for some super-cool sounds. kinda pricy for a new one though.
:o
Dang man, Your etches are just pristine! I LOVE the artwork on this one. Well done!!!
I finally got the chance to pay all the deserved attention to this build Pryde. What an AWESOME demo! And the pedal looks GREAT!!!
I loved the cello sounds, LOVED them. As to the other two flavors, very nice, I love the low gain, the second one. The stoner rock sound I liked as well but ultimately I felt like your particular build lacked some low end and some bite, some anger if you will, but that might be a result of certain settings you used or if you have a lighter pick attack. Not a bad sound by all means it sounds great, I just wanted it to growl somehow I don't know. But I am almost certain it has to do with the pick attack while you play, I do admit that personally I torture the strings a lot while I am playing, and I do feel that this effect needs that. Still, I don't own a Pharaoh build. I don't. I made a couple for friends and they are over the moon with those but personally I don't need one since I don't use that type of sounds live [yet].
I don't really think Pryde that this kind of fuzz is for you, or me to tell you the truth, I might be wrong. I have a feeling that we both come from a "tighter" background since we love the preserved pick attack and kinda dislike the overly compressed and flubby low end sound...I got a little bit out of track here, sorry, the bottom line is, your pedals sounds like it should, and If you are not perfectly satisfied with it don't sweat over it because some people that I know can make a NYC regular production model muff sound like the tightest craziest meatiest thing ever, and when I approach their setup and try and play it sounds like total crap.
It's a great pedal it can really do a lot, but I remain faithful to the Fuzz Face, Rangemaster, Centaur, and other types of dirt.
Cheers! Looking forward to your next build friend.
Oh, and you should definitely pursue that ebow cello playing style, it sounds fantastic! we want to hear more of that! [and you are right, this pedal really does the trick with that!]
@Cortex
Thanks for your listening and giving some good, honest feedback. Overall I am pretty happy with this one honestely. There are 3 "complaints" I might have with it and your insights where spot on. I would like more pronounced pick attack (could be by playing style thats at fault), more bass/low end as you said, and finally I find the noise floor is pretty high. I get a lot of hiss even at low gain settings.
Of course, the quest for fuzz will continue as it is written by the Gods ;)
Hm, well actually I was thinking of going in another direction to be quite frank. If you wait a little I might get a layout going soon of a fuzz pedal that I intend building for myself after initially having it built for my bass player.
Nothing fancy or groundbreaking in there, I was just adding features after every rehearsal basically.
It's a Devi Ever Soda Meiser with input and output caps bumped [cause it's for bass], but then I added a clean blend, and in the end I put a LPB-1 booster on the output to increase the volume that the clean blending stage seemed to got a little decreased.
I am telling you that thing rips on guitar. It has no tone control, but I might try putting a James tone stack in there. Baxandall, or whatever it's called.
So the end result should contain a pcb with board mounted pots [though if I go baxandall I doubt they will be board mounted], and electronic switching, Wicked Switches style with momentary switch. I might start a topic soon, cause I have never designed a layout so help would be appreciated.
That thing is a bomb on bass and a muff killer, but I LOVED it with my Tele so much that I am willing to do this.
What guitar do you usually play btw?
Man that sounds like an awesome circuit idea. I would love to try it out. I also don't do circuit layouts but am considering to learn eagle and start that journey soon.
As far as guitars I give equal love to my Les Paul, Strat, and my P-90 equipped tele. They all shine in their respective areas for sure. The pharaoh demo was done on the LP however as the humbuckers provided more gain and meatiness.
Just saw this. Great build and great demo.
I was trying to figure out how you got that drone sound. The bass notes while playing the higher notes on the Ebow. Was that two tracks? Reason I"m asking is, I've got an Ebow and need to figure out how to do that!

Yep 2 tracks just using a looper (TC Ditto). just ebow'ed the top E with the looper on then played the ebow over the top of that.
I'm on my phone so can't check out the demos, but between this fantastic build and all the good things I hear, and Cortex's build, I'm sold. Etched me a board from a pharaoh layout I found....can't wait.

Thanks for the reply. Great idea. I love your demo's.
Great job mate! and the Phrygian played fits perfect with the Pharaoh :P
Cheers
Sweet etch man, fantastic graphics
