xxmartinxx's review"This is not a subtle fuzz box"

Zvex Fuzz Factory
- Volume knob
- Gate knob
- Comp knob
- Drive knob
- Stab knob
- 9 Volt adapter requires modification or replacement bottom plate.
- Hand painted enclosure
- True bypass


With the Gate, Compression, and Stability knobs, this is far from an easy fuzz pedal to get to know. In fact, I found it quite difficult to find good, usable settings on my own. Luckily, the ZVex website has a few sample settings to try. Those work fairly well. Still, tweaking can be hard to do on the fly.


How does one rate the sound of something designed to sound, well... like a fuzz pedal? The interesting thing it, this pedal tends to be more raunchy and nasty than most. There are many noise type players who would absolutely love this pedal. There are many other players who are looking for a classic fuzz sound that would be left scratching their heads and cleaning their ears after playing this one. Consider yourself warned.


It seems there are as many fuzz pedals available as there are stars in the sky. Everyone makes a fuzz pedal. This one is slightly unique as it doesn't appear to be based on a Big Muff. Again, that will be great to some and displease others. If you like a smooth, refined fuzz tone, this is not the pedal for you. If you like whacked out sticky gooey fuzz overload, this is one you might want to try out.

As all things ZVex, the price is up there. Most times I find that the price is not justified. This pedal, due to its unique sound might be. I still think it's a bit too highly priced, but if it's a sound you like it will probably be worth it. It's probably better to stick with the less expensive Vexter series to save a few bucks since I believe them to be the same thing, just with a non-hand painted enclosure.

badgerific's review"Better off with the vexter"

Zvex Fuzz Factory
This is a fuzz stompbox made by Zvex. It has 1/4" input and output jacks and can be used with a 9V battery or a standard boss style power adaptor. It's true bypass and has five controls, which are: Volume, Drive, Stab (stability), Comp (compression) and Gate.

The difference between this model and the vexter series is just cosmetic. This model is hand painted where as the vexter is screen printed.


This pedal is simple to set up, just plug your amp and guitar in and put a battery inside and you're ready to roll. The five controls on this pedal are very interactive and can react strangely in certain settings and produce feedback. It can be quite difficult to get a traditional fuzz tone out of this pedal I find, but then again if you want a traditional fuzz sound then you're probably not going to be buying a fuzz factory.

One thing I dislike about the utilization of this pedal is that due to the small enclosure and high amount of knobs it's quite easy to knock your settings when engaging the bypass footswitch.


I really love the sound of this pedal the germanium transistors sound amazing. The range of sounds you can get out of this pedal are ridiculous. My personal favorite is a heavily gated "velcro-fuzz" sound. Like I mentioned previously in certain settings this pedal can be prone to produce wild feedback and oscillations, I really like this feature of the pedal but a lot of people can be put off by it. I enjoy using it to produce a huge wall of fuzz sound that trails into oscillation. The pitch of the oscillation can be changed by the volume and tone controls on some guitars I found so there is possibility for new creative aspects which aren't available with other traditional fuzz boxes.


Overall I think this is a great pedal but I can't justify the price of owning a real one and despite building more than five clones I haven't managed to get the right sound yet. I think if you're considering this pedal you should try it before you buy it as it isn't for everyone.

I think that that this model is ridiculously priced compared to the vexter series considering the only difference is the paint work on it, this is why the overall opinion score is low on this pedal.

Zvex Fuzz Factory
I bought one of these pedals a few years ago. I wanted to get a tone from a fuzz box similar to what I like about the Big Muff but with a few more options. Well after about 30 seconds with the pedal I found out it doesn't anything like a Big Muff. It wasn't very thick and warm. To me the sound was thin and metallic and not very pleasing to the ear. It had a unpleasant buzzing sound to the tone that I really didn't care for.


The Fuzz Factory from ZVex is a 5-knob fuzz pedal with 2 old-stock '60s germanium transistors. Though the circuit isn't modeled after any one specific classic fuzz effect, it delivers tones straight out of the 1960s. These 5 knobs control the Fuzz Factory's parameters at various operating levels, letting you shape your own personalized fuzz. ZVex designed the Fuzz Factory to consume less energy than other effects pedals. When on, the Fuzz Factory's current is less than 3 mA. This fuzz pedal is hand-painted and assembled by hand too so each is unique. Includes a 9V DC power jack and green on/off LED.

ZVex Fuzz Factory Controls

Volume: Output level
Gate: Squelches noise after end of sustain. Turn to the right to eliminate squeals, hiss, and buzz, stopping just as they disappear, or use to tune in exact feedback pitch. Turning to the left opens gate.
Compress: Adds attack characteristic when turned to the left, which gets softer to right, and suddenly pinches tone when all the way right. Also tunes in fat, feedbacky fuzz. Lower the Stability and see what happens to this control.
Drive: Increases distortion when used as a "normal" fuzz and adjusts feedback pitch and tonal thickness.
Stability: Use to control feedback pitch. This is one of the pedal's more finicky controls, so it will take some experimentation to get it right.


I was not a fan of the sound as I had previously mentioned. I was recording with the unit and I did get a fun usable oscillating feedback noise that tracked very well. But the overall tone of the unit was not what I wanted.

If you want to know how this thing sound in a recording situation then listen to the band Muse and the song "Plug in Baby". The opening guitar riff is all Fuzz Factory. I have to say that the pedal tracks quite well. And if you are going for a sound that is unlike most distortion boxes then this pedal might be up your alley.


I am just not a fan of how this thing sounds. I don't find it to be very pleasing to my ears. Many people like the unit and it is for some, just not me. If you want a thinner sounding fuzz tone instead of the thick meaty tone of the Big Muff then this might be your pedal. I'm just so used to the Big Muff as far as the standard of fuzz pedals that this unit didn't please me.

At new they come in at around $300 for the hand painted, They have other versions of that the hand painted that come much less in price but with the circuit inside.

This is a tube distortion pedal, similar to the original distortions by Electro-Harmonix and Germanium. This pedal comes with a power supply, and has two 1/4" jacks for input and output. It isn't rackable and can't be edited with a computer or controlled with MIDI.


This is a relatively easy pedal to use, and it gives you a pretty wide variety of tones to choose from. There are five knobs which control the timbre of the sound. There are knobs that control volume, gate (the noise gate that comes built-in), compression, drive (similar to gain), and "stab" (which I don't have a technical explanation for other than it stands for Stability). Stability is basically the amount at which your signal (the fundamental tone) cuts through the mix. Stab is what allows you to have a more passive fuzz or a more in-your-face, physically present distortion. Between these five knobs, there is a ton of control to be had with this pedal, though be forewarned; only really heavy sounds are coming out of this guy.


The sounds that come out of this thing are wild, extreme distortions. I use it with my Fender Strat and I have to make a lot of use of the noise gate in order to even get it to work. When it does though, it sounds incredible, especially for leads. I like using it with my Les Paul as well, since that guitar is better for really rocking out anyway. The range of sounds is pretty drastic for a pedal that is so uniformly heavy. This pedal ranges from newer sounding alternative/hard rock rhythm tones to classic Zeppelin-esque rhythm tones. I particularly like how much my tone can end up resembling that of Neil Young when playing with Crazy Horse. That sound is enormous and heavy while still being clear, and that's one of the great things about this pedal. Different setting will accentuate different overtones, making the capability of producing interesting noises pretty easy. I think that this is definitely a pedal for someone who explores heavy rock predominantly. I don't think blues/rock or folk-rock players would be too crazy about this pedal. But for those who are interested, this thing is pretty amazing.


I'd highly recommend this pedal to any really heavy rock fan, or someone who's really into distortion in general. This is sort of comparable to a big muff, but it's got a lot more control and arguably superior tone (I'm still not sure which pedal sounds better). This thing is kind of expensive, about $300 new, but I'm sure you could possibly find a used one around somewhere. It's definitely worth the price considering how transcendent some of the effects are on this thing.

Zvex Fuzz Factory
The Zvex Fuzz Factory is a versatile fuzz/distortion pedal designed for use with electric guitar, but of course usable with any electronic instrument. The pedal is made up of analog components, boasting new old-stock 60's germanium transistors. The Fuzz Factory has standard 1/4" connections and 9 volt power is needed. It isn't rackable as it is a stomp box.


The make up of the Zvex Fuzz Factory is generally pretty easy to understand. I should say that a have a lot of experience working with distortion and pedals in general, but I believe that even if you didn't have too much experience that you'd be able to figure out how to use this pedal pretty quickly. The pedal has parameters for volume, gate, compression, drive, and stab. The manual should help you out if you're unfamiliar with what these types of parameters will accomplish.


Generally, I'm a big fan of the tones that are possible with the Zvex Fuzz Factory. You've got your standard fuzz and distortion tones that can really rip, but it also has the capabilities to go beyond these basic tones. Having the built in compression is a huge plus, and for me is one of the best parts about this pedal. I have used the Fuzz Factory for recording in tandem with a Fender Jazzmaster and a '65 Fender Deluxe Reverb, so I got a great idea of what the pedal truly sounds like, and let me tell you that I like what I hear!


While a bit more pricey than most fuzz pedals out there, what you are getting with the Zvex Fuzz Factory is versatility and top notch craftsmanship and build. The pedal is built like a brick, and I've seen it come in a few different very cool looking designs. I'd recommend checking this one of for sure if you're looking for any sort of fuzz or distortion pedal, as I think that you'll be very happy that you did so.

MGR/Donald B. Mayne's review"Zvex Fuzz Factory"

Zvex Fuzz Factory
I purchased this unit new on eBay for $224 shipped. I bought this unit because I was looking for a flexible, frankly crazy, fuzz/sound generator.

My question is, what's not to like? Mr. Vex's claim is that the Fuzz Factory helps the user to shape his/her own personalized fuzz. My problem is that I don't have a personalized fuzz. Indeed, this unit is the quintessence of experimentation. The tones that one can get with this unit seem limitless, from overdrive that cleans up well (despite complaints to the contrary from naysayers) to Atari/synth randomness. Really, there is nothing this cannot do.

I have no complaints with it personally, but I do some have caveats for those who are thinking about purchasing one:

1) The price. This unit is not cheap. I had a tough time deciding to purchase it, then a tough time justifying its purchase. Not that it's bought and paid for, I'm glad I did it.

2) It's not subtle. Yes, one can set it for a nice overdrive - a pretty nasty one. Again, I'm not complaining - I knew what I was getting because I tried one beforehand. I recommend that potential buyers do the same. It's not for everyone, but everyone should try one anyway.

3) One must purchase a Zvex power plate if he wants AC power. Here, I would be remiss if I did not mention that the battery life is said to be at least three years! This may render this caveat moot.

They don't come better made; plus, Mr. Vex guarantees the unit for duration of HIS life. If it breaks, he will fix it, free.

Again, the Zvex Fuzz Factory is not everyone. Instead, it is tailor made for the experimentally minded, and those who want to add a touch of zaniness and unpredictability to his rig. That said, I give it my highest, most enthusiastic recommendation.

KirKill's review (This content has been automatically translated from French)" uh ...."

Zvex Fuzz Factory
Germanium Fuzz
1 volume knob, output level
Gate 1 button, level of feedback
Comp 1 button, attack level
1 buoton Drive, level of fuzz
Stab a button, the signal level of stability




Well there it is ultra space as Fuzz, nothing to do with vintage Fuzz as the Fuzz Face or Tone Bender, this is really something else we are in the modern Fuzz sound is very sharp and clean it lacks bass, use alone is not his strong it must be coupled with an overdrive to give the body if it sounds a bit empty
For the fact that the Muse by severe against the plans for the Hendrix Fuzz I prefer my Red and plans Led Zeppelin, Rolling Stone I Stone Bender


Super expensive in nine to 299 € so there is no ... in secondhand to 180 € here OK why not, if one seeks a good fuzz and modern for that she gets it
I think it's a good addition and it puts a little fantasy in a very conventional effect today
To try it anyway because it may be surprising at first

Guitar14's review (This content has been automatically translated from French)

Zvex Fuzz Factory
Pedals to "plant a Fuzz"
Analog technology.
For a connection between an output jack & 6.35
A switch and a conventional 9V power jack on the cot


The PDAL has 5 buttons "flight" "comp" "gate" "drive" "stab"
Hsiter not have the turn in every sense the magic sound of fuzz factory apparatra fairly quickly.
I do not find it complicated unlike other opinions just take a quarter of an hour it is rgl!


Undoubtedly the highlight of the pedals.
Literally making the fuzz factory!
It produces an excellent record for the most fuzz lgre most DLIR most psycadelic!
A superb pedals.


I use it for six months, it did not default
I tried other fuzz, but nothing compares to the fuzz factory. The quality-price ratio hardly fort.Mais with exprience I would do the same choice.

Zvex Fuzz Factory
Very beautiful piece hand painted and comes in a small red cloth with an elastic closed and dice colored porcelain.

It looks like a toy until we branch ...

So far I have pedals and I tried, did qu'alterer sound, this one, it will set up the sound! Even with the guitar volume to 0, it spews evil overtones and whistles incredible! It's great!


Settings interact with each other, and you really experience it. What is funny it's still possible to vary the current settings of games. No wonder some are what the effect is integrate directly into the guitar.

By combining it with other effects, notament a wah wah, you can really put the guitar and create sounds just by playing with the settings. She is very sensitive to changes in tone.


It is very rich, very full, very fat, but it is a part of all the fuzz I've tried, this one stands out completely I think.
I find it sounds really interesting.
In my tests, so I fired my vox wah wah and my Whammy in addition to the fuzz, and without touching anything, pedals or guitar, I had a car engine in full acceleration that was changing. I tell you me, this pedal is alive!
And beyond the experimentation, it creates fuzz that I find unique and again very nice to play.


Well, as everyone over the years, I tried playing with a bow to Jimmy Page, the cordless drill near the microphones to Van Halen, a wah wah blocked half race for Zappa, the Whammy in all directions to Tom Morello, the Frampton talk box to ... But I must say that this pedal fascinates me, it has a soul.
I've had two weeks and I keep using it, and to discover new sonic possibilities.
I do it again this choice without problems

Everything has been said below.

It's the same model as the Vexter but it is painted by hand ... This gives an authentic artistic side

This painting is fragile ..

Fuzz pedal with AC128 Germanium transistors. In the distinction of having a button which makes the pedal STAB unstable and generate feedback.
No tone knob .. ale that is a major weakness.
Made popular thanks to Bellamy of Muse.


Complicated but that's what's funny. All settings are interraction ..
The volume is very poorly staged: 3 is much too strong, the rest of the race of the button serves no purpose except to his amp Bouzille


His heavy powerful, but very acute and criada. Bellamy uses large corrections EQ. It is a shame ... where is the TONE knob sniff


Original pedal, but its unusual with large faults I love her anyway because it kills.
There are some very good alternatives to this pedal in the same spirit (the Devil Inside by jmb experience with a tone knob and a more bold): http://jmb.experience.free.fr
