24 ideas on “ Creating a germanium fuzz face guitar pedal ”

Could it be just me or will i spy, with my little eye, a connector not linked to *anything*?

Could it be safe to place your project ideas/photos/papers on facebook? Before I checked their usage agreement virtually forced you to definitely provide them with 100% usage legal rights of anything you publish there.

@George: Appears like it’s a connector to have an exterior power. He’s two 9V batteries connected internally, so he’s most likely saving the exterior connection like a final touch.

HA HA funy i’d my facebok page open in another tab and it was confused just a little through the hack approaching on face book. Can’t wait to construct my very own box!

🙂 Other people get Deja Vu to UP! As he introduced themself?

Sorry, I won’t visit Indestructibles, or Face book.I love my computer.

transistors and something the schematic, Op-amp around the board .

Hi George, this photo is by using the very first circuitboard that was later replaced. Among the batteries seemed to be removed as well as an exterior source of energy was connected to the ability supply connector. Because the pedal utilizes a positive ground I left this till last to connect in order to make certain the circuit labored properly prior to getting in to the weird power circuit.

The write down is confusing. This pedal is a mix of the Dallas Arbiter Fuzz Face and also the Colorsound MKII Tonebender. There’s no equivalent pedal available on the market there never continues to be. To the very best of my knowlege I’m the only person to produce this type of device. While Jimi Hendrix certainly had his pedal modified as did Jimmy Page neither of the two visited this extent. Jimi Hendrix was a hacker but trusted Roger Mayer to complete the dirty work and soldering for him, Jimmy Page wasn’t. He simply heard sounds and requested others to ensure they are for him.

The photos are published on Facebook and also the video is online. I recognize the implications of utilizing Facebook for hosting my photos with consider there’s nothing really proprietary happening the actual good with this. This is actually the public connect to the photo set. You don’t need to become a person in Facebook to see them. I’ve selected to make use of Facebook for hosting them since with Facebook I’m able to control who are able to discover their whereabouts and whether I would like them private or public.

Tim, the circuit uses 3 AC128K milspec Germanium Transistors. there aren’t any opamps within the circuit. I made use of nick sockets when i described within the video to avoid getting to solder the transistors however this didn’t exercise and also the entire board was scrapped and replaced and also the transistors soldered into position around the new board.

I wasn’t criticizing the selection, Doug, I requested because I’m interested too in publishing ideas eventually but Instructables is terrible and Facebook raises some concerns. This project is certainly not new while you authored, what whether it was?

I’m considering putting the interesting stuff off Facebook and posting merely a link onto it. Does any expert determine if it might be enough to avoid Zuckerberg make money from my work?
Let’s say the fabricOrpress is released under Creative Commons and also the software under GPL licenses? Would that invalidate any attempt by Facebook to learn solely from this?

i built a fuzzface before, very good for beginner guitar effect project
i understand his schematic differs but here’s one-time the initial design

i believe i made use of the NKT275 transistors

if you wish to enter into guitar effects there’s a couple of websites dedicated to that
http://www.diystompboxes.com has an excellent forum where many of the boutique pedal makers publish.

Not a problem texting. I’ve done a tiny bit of research and photobucket and flickr as well as their ilk will always be public constantly and also have much more draconian statements about IP becoming their own basically use their professional services. Basically desired to retain IP of my materials I’d distribute them online of my very own. For this reason I haven’t published the schematic yet.

I’m undecided on whether I wish to release it. Things I did wasn’t hard to determine however i did hafta determine lots of other activities to make it work correctly and play well along with other devices. Exactly what do everyone think?

@zool your correct it used the NKT275 PNP transistors. The MKII Tonebender used the AC128 PNPs. I had been initially using OC75 PNPs. The issue wonderful these is gain drift when i mentioned within the video. Within Arizona the summer time temps get extremely high and thus render these transistors useless. For this reason within the video I mentioned which i switched towards the AC128k transistors. They’ve an aluminum heatsink and may withstand temps as much as 500 levels F without any gain drift. All of those other specs offer a similar experience otherwise exact with another diffeerence which being voltages of operation. the AC128K can withstand voltages as much as 32 volts. Which means this has me considering doubling the availability voltages or perhaps tripling these to 28 volts. This obviously brings subsequent issues with seem. At greater voltages the seem is going to be cleaner therefore negating the fuzz distortion which is why behind all this. You never know though. This can be the beginning of a brand new kind of overdrive pedal! Germanium overdrive a la Jimi or Jimmy anybody?

Ok here’s what I’ve made the decision to complete. Since I Have do value the quantity of discovery and engineering I’ve come up with to produce this pedal I’ll simply publish links to each one of the schematics and articles I referenced during its creation and engineering.

Here goes:
To begin with the fundamental circuit may be the Fuzz Face. There’s a lot of details about this pedal online but this is exactly what I did previously create this pedal:

Now… The Colorsound MKII Professional Tonebender circuit: Be cautioned this can be a beastly fuzz pedal. The circuit isn’t to complicated as it is just one gain stage greater than a typical Fuzz Face put into the leading from the Fuzz Face circuit. You might find details about the MKII Tonebender here:

Here is the particular schematic I made use of:

You’ll note there are lots of variants of every schematic and pedal. I particularly find the earliest versions of every pedal to utilize due to the fact fundamental essentials ones while using Germanium Transistors. Later versions of these two pedals switched to Plastic Transistors which altered the seem. Many people like the seem of Germanium over Plastic and the other way around. Some people even prefer to combine and you’ll encounter many such circuits around the www.

The issues with these sorts of pedals are their strange POSITIVE ground power (on earlier models) and transistor gain drift with temperature (also on earlier models). Later models switched to Plastic for stability and consistency as well as being less expensive. Transistor biasing can impact the seem and sonic tone of those pedals and you may certainly hear variations from a bad or good biasing from the transistors. Generate income recommend to construct the circuit is on breadboard so that you can swap out biasing resistors to tweak the circuit for your particular transistors as well as their specific gain structures. Take my word for this. It will likely be much simpler to complete on breadboard then once you have already soldered the board together. There are many locations to get Germanium Transistors. Steve Daniels at http://www.smallbearelec.com provides both gain tested and pre-biased transistors and resistors sets. Also, he provides non-tested transistors for any couple of dollars less however, you must measure and test each transistor to locate its gain and biasing resistor amounts etc… Or otherwise! The businesses that built these pedals did no such factor. They just built pedals while using next part grabbed from a bucket of parts. So with this stated a dark tone is entirely up to you.. Its your pedal so construct it therefore it sounds amazing for you and that’s adequate!

A summary of my other projects might be found here:

In case your not really a mamber of Facebook i then apologize and disregard this publish.

Can someone explain using germanium transistors versus a likewise spec’d plastic transistor?
I’ve heard numerous people say there is a ‘warmer’ or ‘more clean’ seem for them, but what am i saying electrically? Isn’t there a great way to duplicate that seem without germanium transistors?

@Spork… First allow me to state that “Tone” is subjective and varies for every person.

To reply to a couple of questions you may have. When I have mentioned plastic transistors tend to be more stable then GE trannies because of heat instabilities. To be able to substitute SI trannies for GE trannies the circuit should be re-biased to closer match the specs necessary for SI trannies. What this means is added resistors and caps to stabilize the circuit therefore the SI transistors could work properly. Electrically what this means is different impedances and voltages. This means different gain structures and various ripple filters than the original GE circuits. They simply seem different. For emulating the seem from the GE trannies this can be achievable through DSP but I wouldn’t rely on setting it up to seem exactly the same. A minimum of a maximum of emulating the seem of tubes versus solid condition sounds realistic. To actually appreciate this you’d require a solution discussing atomic structure and physics.

@Spork: besides being generally worse stability-wise than plastic transistors, as Doug stated, generally germanium transistors in addition have a limited bandwidth so that they gracefully cut the greater area of the audio spectrum which provides their less harsh seem when compared with silicons with regards to distorion (we’re not speaking about HiFi where silicons outshine germaniums in each and every aspect).

This is often _somewhat_ emulated with plastic transistors with the addition of a little capacitor (a couple of hundred pF max) between base and collector of every transistor. A resistive trimmer in series using the capacitor will help moist our prime frequencies to the quantity of your decision.
Don’t expect this trick to create silicons seem just as germaniums but for many people might be enough.

@Doug and texting
Just responses. I wouldn’t go so far as DSP, since i might as well used that in the beginning.

texting, which was my thought exactly, I’m wondering basically can use a higher pass filter to imitate the smaller sized bandwidth from the germanium transistors.
I’m presuming this little trick is going to be enough for me personally as I’m a good bit deaf.

If only I had been smart enough to construct my very own custom pedals such as this.

…since I had been literally inventing the wheel here…

It was meant and utilized in a figurative literation. Nobody has built the circuit when i had and that i required to figure a couple of things out.

Trust me, there’s NO seem just like a germanium fuzz box.

I made use of em once they made an appearance. Used one out, went through a number of other boxes, and today have laid on the job an authentic 60’s model.

Tone is smoother, creamier — ruffer possibly – but that you can do more with than later designs. Least, I’m able to!

It appears as if I’ll hopefully be manufacturing a few productions runs from the new version of the pedal. Same specs and transistors and mostly exactly the same circuit but 4 modes of operation instead of the 3 modes this pedal has. Incidentally who owns this pedal still loves it and uses it everyday both on stage as well as in the studio. I additionally built his custom-designed 100 watt tube amp along with the funnel switching device. He’s didn’t have problems whatsoever previously four years with them. The only real things in the rig I didn’t make were your guitar and also the cords and also the pick. I’ve made two greater number of these pedals plus they offered immediately. I barely had the capacity to complete them simply because they were so eager for their services. The creamy lusciousness from the germanium enables full guitar chords in addition to single notes unlike lots of modern distortion devices. I’ll make a comment about this thread once the new pedals are for sale to purchase if anybody has an interest. I haven’t had time nor the area to complete any electronics work previously couple of years because of existence and medical conditions but now i’m to stable again so search for new devices again soon!

Dunlop Fuzzface Reissue vs Electro Harmonix Big Muff

  • Mak Baltezar Leviathan: Fuzzface!!
  • Kevin Jamieson: What are those pedals on your left?
  • Matt Gilbert: The real difference here is that one is a FUZZ while the other is a MUFF.
    Shocking, I know – but it's true.
    Up next: Boss CE-2 vs MXR Phase 90!

  • LEXON4X: big muff <3
  • spando dongdee: I seem to be the only one that runs my signal through an overdrive channel on my amp, so these demos are usually useless for me because it will always sound completely different
  • Jaime Julian Peters: I went for the Big Muff Pi. It does it – and that's why I bought one. It's classic fuzz.
  • Jaime Julian Peters: I own the large Big Muff Pi – there's nothing like that baby. Legendary kit.
  • dezionlion: need more dirt on amp and crank the fuzzes!
  • sagrado5: Fuzz face for me
  • qwerrewq qwerrewq: Как при таком оборудовании умудряются получать такой дерьмовый звук,уму не постижимо!
  • Donavans covers: Fuzz face for me man, I dig the not so fizzy crunch you get when the fuzz is about half way up.
  • Damn its Arafah: i don't know but, i think Vox into Big muff isn't just the right thing. those two just never work right.
  • Konssienssrassial: i'd like to see a Pi vs Caprid vs FFM2 vs Lava Box vs HM-2 vs OD-1 video
  • Sérgio Silva: Fuzz face!
  • Ringo Gingo: wearing that jacket is a great way to scratch up you Fender
  • Alex R Starreveld: Fuzz Face works better in tandem with amp gain and melodic lead work. Big Muff if you use purer clean channels and for rhythm or sustaining leads.

    For me it's the fuzz face 🙂

  • Johnny Teisco: I choose the Big Muff because I don't wanna crank my amp or buy an extra overdrive pedal to make a Fuzz Face sound good.
  • Orlando Wilmer Sanchez Neira: Big Muff pi… ? ? ?
  • Vinnie B: love your videos and demos, man
  • Hearthis: Fuzz sounds so much different in a really clean amp
  • Jimmy Page: I dont know if it's just me, but I just cant get into fuzz pedals no matter how hard I try. I try my best to enjoy and buy one, but it seems everybody loves them but me. I have full respect for anyone who plays them or makes them, but I cant think of playing one.
  • Matt Evans: Fuzz Face, unequivocally (and subjectively) wins hands down!

    Seriously though, very different fuzzes with different applications. The Fuzz face is a smoother, woollier fuzz, which very much interactive with the guitars volume. (which is why I like them) Muffs are tighter sounding, more spiky; they don't really clean up the same way. Both sound awesome. You probably need one of each.

  • caterina russomanno: quite the same
  • Zayzay 123: Big muff
  • Robert Rawlins: Muff hands down!
  • Ivan Brzezinski: Big Muff offers a bigger range of tone variations
  • William Mouser: the Face! Muffs sound too scooped and loose. That face has a tight thick mid punch and grind that I love.
  • Nicolás Muñoz: who's this guy? I'm sure i've seen him before, is he famous?
  • 24lighter: BIG MUFF IS EPIC!!!!!
  • Auxend: thanks for doing this on a vox ac30, really helpful, I'm a huge ac30 fan and I have to say I think the dunlop serves it better for my taste
  • james Doctor: Fuzzface owns the big muff. Big muff was wayyyyy to mid rangey
  • Amazology: Both…but forced to choose. Muff.
  • fuzz j: is the germanium fuzz face?
  • Arlindo Aesthetic Bodybuilder: Big Muff sounds better with Les Pauls
    Fuzz Face sounds better with Strats
  • M M: Nice comparison. At one point I would've preferred the Big Muff, but I like the warmer, grainy, middy Fuzz Face these days.
  • Anuj Upadhyay: Very good video comparision! would they sound the same with a traditional les paul?
  • Rational Lunatic: Jimmy would be proud
  • joshm17: What would you think would be the best to suit a beginner for blues? I've only started getting into blues, as I am mainly a metal or rock guitarist! Thanks in advance.
  • Pól ‘s Eye: To me the Fuzz feels 70's, the Muff feels more contemporary.
    I like them both equally; still can't choose!
  • Alex Patel: Good comparison. The big muff has more gain, a smoother sound, and is more versatile. The fuzzface is lower gain and a bit gritty. Both are great, and are better for different sounds
  • Ari Lutfi Wahyudi: i like the grit from fuzz face. big muff it's like it has too much gain and smoother sound
  • Marek Tokarcik: Its hard to not use Fuzz face as a one trick pony – fuzz pot full or almost full and yeah muff sounds like a muff
  • Sid Fernandez: also, for fuzz, check out the octavix by electro-harmonix. i've got one, love it, made a demo. check out my channel n let me know what you think, guys. click sid fernandez. thanks!
  • Mike Anderson: its all about the BIG MUFF for me
  • Brian Taylor: You sound like Jack Black! Oh wait….
  • Igor Volhovsky: Fuzzface up!
  • RhythmGrizz: muff wins
  • Antonio Alvarez: Thanks for the vid, this is what I was looking for and yes, they are 2 worlds apart..
  • Terry Masri: You have an early Trower vibe dude! Not the playing… the look I mean! And that's a great compliment as far as I'm concerned. Thanks for the great demo!
  • Terry Masri: Liked the Big Muff more until you kicked-in the C.C. delay. With delay, the Fuzz Face sounded more balanced, but more importantly, had beautiful upper harmonix that the BM lacked… to my questionably discernible ears that is! A poignant demonstration that FX to music are like spices to food. It's all about how you mix and match.
  • Neil Kraft: both sound like walmart urinals
  • Alessio Pastore: Fuzzface all the way for me
  • Beeastman123: Doesn't Jimi put fuzz before wah?
  • Beeastman123: Best place to put a big muff in chain? With wah and overdriven?
  • Ben Lyman: Check out the fuzz pedal I made from germanium RCA transistors that I took from a 1960's radio:
  • Norman Bfifteen: Big Muff always wins these comparisons
  • Norman Bfifteen: No comparison! Not even close
  • Michael Kelly: Big Muff has a lot more grit, not really a trebly sound but has a bit of flavour almost like its a little fuzz with a little Over Drive. The Fuzz Face is a little bit fatty for me
  • toadamine: That's a knockoff fuzz face… Notice there is no "smile" and the ribs on the rubber are going the wrong direction… Also the text is different.
  • Игорь Фузман: FuzzFace is warm, soft and not very gainy, Big Muff is angry, extreme and capricious. I have Muff and I would say that if you spend some time finding a nice tune, it can make amazing stuff.
  • yang vazquez: how did you get a free noise tone?
  • university of utubes/jewtubes: Have the muff. Not keen on any. maybe now and then. still trying to find an amazing muff set up.
  • Kustom Hooligans: Why do ALL Fuzz Face circuits sound like weak, flubby pieces of shit? Even all the Analogman pedal AND both the original 1967/68 FF I've played.
  • Jay Marasigan: The real difference between the two is, the FuzzFace is less gainier with mid hump, and the BigMuff sounds gainy but has a scooped mid. That's all.
  • Max Sturm: BIG MUFF!!! For sure!
  • EarlKrempe: SHNOBEL! You look like a young robin trower. 

    That is all.

  • Tramp: The Fuzz Face is more refined, and sounds tighter…  I like it.
  • Marek Tokarcik: Face – germanium… Muff- silicone – just put some clean boost pedal with buffer before and you need both
  • Cletus Kasady: Muff FTW.
  • victor ortiz: two legends…
  • anthony mallia: bend man to see the real deal
  • cominroitover80: that fuzzface sucks ass. The Fuzzface mini's they just released sound way better imo
  • Gabriel Castellar: Fuzz face.
  • Gabriel Castellar: Fuzz face for the win!!!
  • Elliot Often: Big Muff wins.
  • southgooner86: Did you have your guitar volume up full when you tried this? It kind of, sort of, doesn't sound like it is but I can be wrong. This will effect the sound of the Fuzz Face in a big way – more so than the Muff especially in terms of interaction. Some people see that as a benefit as it also cleans up really well as you lower your guitars volume which I'm sure you know 🙂
  • Isabelle Cristina: Big Muff POwerrrrrrrr!!
  • Liam Lawson: The pie. No comparison
  • Brock Barr: Interesting that everyone so far likes the Muff, I prefer the Fuzzface. Though the Muff does seem to be more versatile. Nice demo, keep 'em coming!
  • Rob N Roll: nice video dude!  Rock on !
  • Simon Dixon: Thanks for another killer demo dude! I'm procrastinating over an all-round kinda fuzz at the moment. One thing that this and a couple of other videos have confirmed is I'm way more of a fuzz face kinda guy than a muff man. At least when we're talking pedals anyway. Childish comments to one side I think it's ability to clean right up is also another attribute when picking a user friendly fuzz. I have a killer one knob colorsound fuzz, but it doesn't clean up at all. It's a monster wide open though.
  • David Price: Big Muff every time!!
  • dflash88: what stratocaster do you play ? i want to buy a fender classic series 50' strat but its MIM :/
  • RIG RIG RIG Gear Demo: Nice comparison, love that raunchy Muff man!
  • STRUMGROOVE: Big muff!
