Also, in a subsequent build of a Silicon Fuzz Face, I tried high-gain 2N5088 … For who wants to try tweaking with the basic npn silicon fuzz … Also, try to find an NPN germanium transistor … What makes them different from their sibling Big Muffs is the method by which they produce distortion (to get an idea about how different they sound from each other, check out this video). So unlike some distortion pedals, the fuzz is not supposed to overdrive the input of your amp. But it was fun while it lasted!!! The Fuzz Face is, of course, a unique circuit. But I want moar volume when I engage. Having done the TS layout I thought I’d do another classic as well. So it has odd harmonic distortion from both top and bottom being clipped and has even harmonic distortion because they are not … I received an email asking if this method of … geofex.com Competitive Analysis, Marketing Mix and Traffic vs. electrosmash.com muzique.com tagboardeffects.blogspot.com diystompboxes.com Welcome to Alexa's Site Overview Post by DrNomis » 03 Jan … The gains of the transistors were all chosen based on the values presented in RG Keen's "Technology of the Fuzz Face" article at GEOfex. Top. Any tips on which soldering tip size, shape, and heat/voltage I should use for PCB? A fuzz face, to go from glassy clean'ish to overdrive to full on fuzz with the volume knob. Bogdan Putintsev. Replace the 470 ohm output resistor with 1K ; Replace the 8.2K resistor at the collector of the second transistor with 18K ; Replace the 1K control in the emitter of the second transistor with 2K. It currently does only a few calculations, but more will be added as time allows. Mid's control in '70 is very similar to Contour knob in '69 - it replaces 470R (in standard germanium version of fuzz face circuit) resistor with 220R + 1K pot in series. Bitsbox stock BC109's and BC183's. Harald. With the volume maxed it's still a little bit under unity, so it isn't a huge drop. The original Fuzz-Face circuit used old fashioned germanium PNP transistors. Paypal Donations! Completed builds: Dallas Arbiter Fuzz Face,Tone Bender Professional Mk 3,Tone Bender 3-Knob,Baja BK Butler Tube Driver,Baja Real Tube Overdrive,Roger Mayer Octavia,EH Soul Preacher,Tech 21 XXL Distortion,MFOS Weird Sound Generator. But there seems to be a ton of variance in sound in just that style of fuzz, which seems to be down to the transistors and how they are biased. Lespaulnmarshall, … The Classic Fuzz Face with Modern Enhancements so it can be used with today’s pedal boards while not affecting the Vintage Tone of the originals. Also, in general, they do not react as well to ‘cleaning up’ by rolling of … I did a googley search but most stuff is amp related, but I found something that said a resistor of about 20% … 0 … The original Fuzz Face schematic is extremely similar, if not identical, to the earlier Sola Sound Tone Bender so-called … It also acts as a high pass filter, removing some bass … The voltages on Q1 are spot on for a low gain silicon fuzz face. You should build either the Axis Fuzz from Fuzz Central or Joe Gagan's Easy Face, on GGG. Messages 391. Post by kierc » 26 Mar 2009, 12:55. i'm pretty … Have you seen how distorted it is? Are both pedals biased at the same voltage? I didn’t go into any details about what transistors to use since this … Im wondering how many people her have one of these pedals? The original Arbiter Fuzz Face pedals were equipped with NKT275, AC128, or SFT363E transistors, depending on what date the unit was manufactured. Mine sucked haha! The NPN one runs from the normal V1 (usually +9V) power supply of the FXBus 1. None of these are readily available today, and those that do exist are quite expensive. It's a like-new Fuzz Face Mini (the blue one, silicon). Old style PNP Fuzz Pedals were positive-ground circuits that required a … My favorite home built Fuzz Face is a combination of both. In '70 it's 220R + 500R pot in place of standard silocon fuzz face value 330R. The pedal is a cross between the Fuzz Face of Jimi Hendrix fame and the MKII Professional of Jimmy Page fame. One of my favorite pedals of all time is a Fuzz Face. Silicon Fuzz Faces exhibit a more aggressive fuzz tone; harder and more intense than the Germanium variants. They all basically have the same tone, but different characteristics imo. More ideas for you. C. Championguitar Member. Fuzz Face) circuit, andsit probablymore interestingfor that. 5E3 – Woody … An example of this is the Fuzz control in the fuzzface examples above. I have a Dunlop Fuzz Face ("Dallas-Arbiter", as it was marketed, but the Dunlop reissue,) the JD-F2 model, revision D. The circuit has a couple more parts than the standard fuzz face, including two gain adjusting trimpots, a few extra caps, two oddly large (330 uF) electrolytics, and what I believe is a thermistor (designated as RT1, perhaps to deal with the … … Completed builds: Clyde McCoy Wah with Whipple+Red Fasel inductor switch, Fuzz Face with own layout Location: Bristol, UK. Bitsbox. with different sections of the circuit (made with Fritzing) The first capacitor (C2, 2.2uF) filters the DC current at the entry of the circuit to avoid troubles with the next part of the circuit. The story of the Fuzz Face is entwined with the the Sola Sound Tone Bender, and the Vox Tone Bender. It's usually best when done with germanium transistors. First Friday of the month for a fiver at Hideaway Bar in Enmore with cheap drinks and great live bands This is the schematicof the whole circuit, less the input/outputjacks and bypass switchingarrangements, which have been left out for clarity about the circuitry. 19 followers. Thanksalso to amscray for providingthe schemofor the Hornby-SkewesrebleT Booster, which is purportedlythe preferredfront end for this. It is simple to build and is very tweakable, which makes it a great DIY project. The Fuzz Face is a great project to really tweak to your preference. Their circuits frequently had a positive ground. Different bias points will affect the tone and feel of the fuzz. Note that the output Volume pot is ac coupled through a capacitor and it is not changed. These fuzz circuits (Fuzz Face, Tone Bender, whatever) actually sound quite good by themselves (that is if you can find transistors with the right leakage, hfe, noise and various other mysterious properties). Magneticeffects Facebook. So that self-indulgent masturbatory session of extreme squared sine waves inducing speaker heat cost me $140. Enter your email address to subscribe to this … From Geofex "Technology of the Fuzz Face" :-There is a set of changes collectively referred to as the "Hendrix" mods or the "Roger Mayer" mods. Hi, Is it possible to say get a 100k Lin pot, do some electric voodoo, and end up with a 100k Log pot?? I would like to build one, particularly the Twin Fuzz.

The trimmers in the link that 11 Gauge posted looks like it would take care of some of the transistor variance, but I imagine that there is still a … My soldering experience is limited to wiring each components in a guitar and making instrument cables. Each transistor is tested for gain and leakage according to GEOFEX (Technology of the Fuzz Face) specifications. Both sounded good, but I wasn't completely satisfied. If for some reason you don't like the sound when using the positive supply voltage, it is easily changed back. EMH is the Electronics Math Helper. Special thanks to Peter Snowberg for assisting with this project. Pots have wide tolerances (+/- 20% is not unusual) and even a 10% difference here can make a … This mod primarily … hmm.. There a host of modifications to the circuit you can find on … I don't really want to mod it, because it basically is like new. Goodluck! It is a DIY standard after all. Guitar Circuits and Schematics: Fuzzi, Amps and other Effects. All easy stuff. Well the great R.G Keen of Geofex has written a brilliant article (many years ago now) explaining just how to do this: "Picking transistors for FF Clones If you have a batch of germanium transistors, how do you tell which are going to sound good and which will not? amp on 10, fuzz face on 10, guitar pretty close to 10. Not that the internet needs another Fuzz Face layout, but I'm adding it for the completeness of this collection. I have a booster anyways, so I just … This follows the stock NPN silicon version with BC108 transistors. Arbiter Fuzz Face (Silicon). I've read up on the Geofex "Technology of the Fuzz Face" article and there are a number of suggested gain ranges to try but I'm struggling to find anywhere that stocks gain matched transistors. This kind of capacitor (that you will find in a lot of circuits) is called a coupling capacitor. Fuzz Face Circuit Diagram. For an in-depth discussion of the Fuzz Face circuit and its operation, see "The Technology of the Fuzz Face". With over 1.4V on Q1C it's certainly possible to have Q2 C measure over 3V (with all stock values). I have the Weller WL-100. Both are excellent projects! 439 likes. I shall see. Compared to other models of the fuzz box, they weren’t made for a long time, so there are comparatively fewer units around. Here are layouts for both germanium and silicon versions of the Fuzz Face, both based on schematics from generalguitargadgets. beavis board project … Click to expand...
