MGR/K-man's review"Electro-Harmonix The Worm"

Electro-Harmonix Worm
I got The Worm at Guitar Gallery of New England and paid 94 dollars for it. I was originally looking for a Wah-Wah pedal but I was having trouble finding one with an extreme enough wah sound. My friend suggested I try The Worm, so I did and it was incredile.

I love the modulated wah especially te fac that if you crank it you can get some crazy sounds, it was just what I was looking for. I have since then discovered that the phaser effect is also very cool, it's one of the best phasers I've ever used. And the tremolo and Vibrato also help make it a slightly better pedal.

I think it is just a little bit to noisy sometimes it can sound like a helicoptor is inside your amp. Also the tremolo and vibrto aren't that hot, they work but if you want those effects buy a different pedal. Also I whish there were numbers or even dots around the dials, so I could remember my settings, but if you take the time to adjust the unit you can get someawesome sounds.

The thing is made out of metal not cheap plastic, it is a tank. I don't think it will ever break.

I love this pedal and highly recomend it, it has brought my playing to the next level.

peenduitre's review (This content has been automatically translated from French)" prefer the "classic" series (vintage)"

Electro-Harmonix Worm
EHX all analog multi-effect
4 Effects: vibrato, tremolo, phaser, auto-wah
I have the first version series "classic"
imposing pedal exudes strength,


easy to use
3 large knobs = very plug-and-play for a multi-purpose!
level desired effect is found quickly
no need for manual


quality and precision analog = it breathes, it lives, it colors the sound as it should
the guitar is respected
all effects are very correct, the auto-wah is the least successful
The +: the "manual" function freezes the effect desired position, removing any pure sine dynamic variation (as if you left a wah-wah pedal halfway example)
the -: for those who use microphones high output humbucker type = saturate it a bit. It will give the best of it with a strat or telecaster.


vintage versions are rare to find
But they are worth visiting because they are warmer than the nano Version
a bit of background noise but plunges us the best album of PINK FLOYD
CAUTION! power is specific, it will not work with a transformer or BOSS for Big Muff

if you are lucky enough to find a vintage: go for it!
but it is rare opportunity

PDAL makes New York, robust design, unchanged for over thirty years at Electro Harmonix. The case is metal.

The PDAL has the advantage of offering four types of analog modulation (hot sound!)
The Wah mode is excellent, it provides absolutely dessonorits gniales and out of the mix for solos or riffs overheating!
The method reminds the legendary Phaser pedals "Small Stone" of the same manufacturer. Cool!
Tremolo mode is a nice tremolo Vintage :-)
Vibrato mode has a fawn efficiently an amp to sound like the 60s, old Fender or Vox, for example ....

The pedals are nickel sounds of Radiohead, Stereophonics, U2, etc ...

4 pedals in one, with the effects of good quality and sound is a typ 10.


VINTAGE respecting its essence, the rglages are-simple, and large knobs allow manipulation of the foot (for scne cool!)

A SETTING THE RPM, a button switch to select between 4 modes, and SETTING THE Range / intensity of the effect.

A modulation switch Manual or Automatic (hint: position on Automatic)

Simple and effective.


Analog effects bring their share of heat. Do not expect clean cold numrique. Here is the sound from the seventies, a little dirty, but so hot Rock 'n Roll.

There are still some Sufi as the effects of what had at first. So, I went back to the store to try other models. Well, all that trmolos jai test blow as much or more. This is NORMAL!

I play the pedals with a custom tlcaster, a US Stratocaster and a Les Paul, Marshall DSL connects to a 401. No problem, a ring with the three configurations.

I put a 9, because there are better (but three times as much just for a tremolo ...)


I used a friend's for a few months, then I DCID buy one.

The Wah mode is compelling for its incisive one coming out of the mix and is Vintage wow!
I use the tremolo a lot, which is essential for me.

I tried Boss TR2, Line 6 Tap Tremolo, Dunlop Tremolo, and Voodoo. The WORM seemed most INTERESTED. Several effects of quality on a single pedals for the price of a Boss!
The ratio quality price is excellent. And Electro Harmonix possde an identity sound I love.

I chose the WORM, and I do not regret it!

Deja is below.
Well yes it is the format Electro-Harmonix, which fills quickly the pedal bag ... Fortunately, there is the sound!
big c, but sturdy, and comes with transformer, still within ca.


While there are only 3 buttons, 4 for effects, so at ease, it's going!
choosing its effect (wah, phaser, tremolo and vibrato) with a 4-position knob, you set the speed of the effect, the period of oscillations if I may say (ahem) with a sacred amplitude, and adjusted the intensity effect with the last button.

Aunt said that the three buttons are simple but very effective!


While the sound is somewhat mixed ...
Say that the phaser is cool, pretty special but can go much, but hey the phaser, I know nothing, I find it nice, but I use it a lot.
The tremolo and vibrato sooooooufflent! and the effects tend ehx change the sound of orgine, irrespective of the effect ask. The tremolo, it Tremola well! but it changes the sound a bit, I found in well, so that's good! but it blows ... and group I am ashamed to use it, means that schhhhhhhhhhh, schhhhhhhhhhh, schhhhhhhh ...
The WAH! I love, in fact if I use other effects too, because I have this pseudo wah, so it's really the main function of this pedal for me. And you can actually vary the wah very fast, a large enough amplitudes funny. It also Pregl the intensity of the effect, say between wah that changes not too low the eq sound with more powerful wah sound dull, then wah very shrill, acute, but so WAH! (My favorite!)
Well I put 8, because for me the wah is really cool, but the rest, although very EHX, owns qques small defects, especially the breath. But the sound is good raiment
Oh yes, noted that the enclenchment the pedal slightly increases the sound ...


Must have for over 6 months
it's really my wah pedal my funkyfiante in pieces
I had not done proper research before choosing the jumbo's, but I know the quality of EHX effects.
value for money is correct, the EHX is still far superior to their price, if you like the sound of.
With experience, I will buy rather the Q-Tron (not tried it yet, so this is hypothetical) because I trouove wah outperforms the other effects, mainly because of the breath of the tremolo, shame, because the tremolo is very nice otherwise. So a "multi-effects", just to utlise that is a shame ... although other effects make me services from time to time!
