The FX57 Hard Rock Distortion was introduced in late 1987, allowing the user to "thicken" their distorted sound via an analog delay of up to 40 ms. The idea of distortion plus delay to thicken one's sound had been previously explored with the DigiTech PDS1550 twin pedal (up to 40 ms of analog delay; introduced in 1986) and the Boss MZ-2 Digital Metalizer (also introduced in 1987), with the FX57 no doubt intended to compete at a lower price point. As its name implies, the FX57 Hard Rock Distortion's maximum gain and output levels are not as extreme as the FX56 American Metal. The FX57's Presence circuit is described as "an equalization circuit that reduces or enhances the bass of the distortion sound", but overall the non-delay portion of its circuit was likely based on the FX56. The FX57 was produced until late 1993.

  • Controls: Delay (0-40 ms), Level, Presence, Distortion
  • From the manual: "The FX 57 is a very high gain preamplifier that is overdriven to produce a distorting effect of the input signal and help sustain the notes longer. These effects simulate the characteristic distortion of a guitar amplifier turned up so high that it 'clips' the signal, distorting it. The FX 57 offers a unique distortion circuit with a built-in delay of 7 to 40 milliseconds for a distinctive thickening of the distortion effect for use in rock distortion sounds. The FX 57 Hard Rock Distortion makes its distortion effect sound at any amplifier loudness setting and also sustains your guitar notes."

monsieur-iks's review (This content has been automatically translated from French)" a good pedal ... fuzz!"

DOD FX57 Hardrock Distortion
What are the effects or types of effects available?

I heard alot of bad about this pedal and I think it is because everyone expects a big distortion. Actually it sounds more like a FUZZ!
the sound is fat and disgusting, ideal for the Grunge or Stoner!
my settings are: Delay: 11/40 level: 7.5 Presence: 4 Disto: 5.5


The general configuration is it simple? Editing sounds and effects is it easy? The manual is clear and sufficient? ...

4 knobs, nothing more simple. I have no manual


The effects are they effective, responsive and realistic enough?

if you want to make a distortion you will probably be disappointed, that was my case, but j'ne have done a very good fuzz with the settings and I find it better than my Big Muff! :)


How long have you been using?

2 months

Did you try many other models before buying it?

the Big Muff, Nano Muff fuzz of VoxTonelab ...

What is so special that you like most and least?

+ Cheap for a fuzz box of solid metal, DOD access to quality batteries

- This is not a distortion, power mini jack not super well located

How do you rate the quality / price?
With experience, you do again this choice? ...

30 euros for a good fuzz is more than reasonable :)
I remake that choice without problem

DOD FX57 Hardrock Distortion
Everything has been said before. 3.5 knobs since the delay is just there to look pretty like "I have a pedal with lots of buttons." I could have seen him put 2.5 knobs presence but it still affects the sound.

Put a delay in itself was still a good idea for solos and all, but no ...


Again I agree with the previous opinion. Manual clear: "Buy our products!" with a few bad tracks for beginners advocating the use of delay that rotten sound.

To the question whether the general configuration and if editing sounds are easy ... Yes, what we do does not sound. It is therefore unnecessary to seek a safe setting.

The case is solid but the battery cover is crossed ...


In terms of sound quality, it is really effective ... To rot SOUND!

The delay is useless, presence can have a choice between a sound and its rotten squarely shit ... The volume is not at all intuitive, ditto for the gain and the bypass does not work.

I tried to put it anywhere in my chain effect, nothing happens. I used a master Lag Arkane 2000, a fender strat, an Ibanez blazer 82, all on a Laboga Alligator + marshall 4x12 cabinet Celestion V30 ... this is an insult to the instrument and the amp! It respects neither the one nor the other and transforms everything you do to mush. Especially as my distos Laboga the second channel are much better.

Frankly, I hate it! I put just one because I still embedded in my effects there was a time when I was playing on a Marshall 15W transistor (rebel style).


I put two good for all items listed above.

The +:

-I have been offered and it's always fun
Box-solid, and luckily for him (kicking repeated frustration)

The -:

It poisoned chalice
-The battery cover

DOD FX57 Hardrock Distortion
Time limit, prsence, distortion and volume, the classic, simple and effective.
Entrance, exit, an outlet.


It RULES, a ring. The simple and effective.


Is the one I made in United States, although it sounds trs, and its numerous rglages, impossible not to find "his" sound.
Trs useful for solos, trs effective rhythm at all good.


I bought it for curiosities I am with exploded.
Incorporated the delay can bring out the solos, the prsence makes you "move" any grateux you ESG.
It should even be right mtal fan of, if not go his way.
Trs good report quality price (I had been used for 50 euros), no dception possible.
I sold it because I do not really mtal, plutt of pop rock and progressive rock.
But if the mtal or hard rock is your thing, you will fill it.

DOD FX57 Hardrock Distortion
Old DOD pedals gnration trs trs is the reliable
4 rglages:
Rglages trs trs simple and effective
Solids are all evidence: the switch does not age with time is incredible
Power as many pedals: 9V battery or AC adapter


I is not the manual, however there is not really necessary. The level-distortion-rglages prsence are common lot of pedals danc there is nothing to be wrong ... The delay is effective and trs trs marries well SETTING THE prsence which Confre the remarkable power pedals, good sustain and if you have a good microphone with it all madness is the prsence it!


I use it primarily with a team of RG 270 and DP193 is Dimarzion DP161F cut breath. The distortion is really top yet but I deprecated the pedals for rhythm is solo she comes into its own thanks to the delay trs rgler effective and very easy. The distortion is kind Hardrock but its efficiency allows it to easily adapt to other styles of music (in the same area even when, n'sprez not play the blues with a n has no record). I thought before having the delay n'tait not terrible ... but we must see the pedals as a whole: I think if you could spare dclencher the delay of the distortion does would not be pretty, but the pedals as a whole gives a trsraliste made, so not too typ diffrent as scratch and allows you to go solo any rhythm too Submitted .


I use it a few years now and I can not get enough. APRs have tried a few pedals just latest issue I think she has little envy the other if it is the level of distortion that is increasing with time and which by the way this is often not trs grate even among larger manufacturers. Yet I am not a fan of these sries of pedals like DOD mtal death, the American distortion ... which I find too many guys. This is not the case at all from that which has the unique charm. It remains all the same very hard in the sr. It's a shame that this PDAL is not known because it would rev a lot of happy. It remains all the same quite rare on the market opportunity but if you have a possibility to acqurir Do not hesitate one day it should be mandatory in every guitarist's collection! !
