Electro-Harmonix Q-Tron (Original)
The general characteristics of the Electro-Harmonix Q-Tron aren’t out of the ordinary, as the pedal is enclosed in a pretty standard shape and design as a number of other pedals made by them.<span> </span>It has ¼ inch connections for input, direct output, and effect output, and is powered by the power supply that comes with.<span> </span>I’m not sure if you can power it with anything other than the Electro-Harmonix power supply, but I do know that most Electro-Harmonix pedals do not have this luxury.<span> </span>It isn’t a rackable piece of gear as it is a foot pedal.


<p class="MsoNormal">Using the pedal isn’t a hard task in the least, as everything is laid out clearly and without dispute.<span> </span>You’ve got parameters in the form of knobs for gain, range, mode, and peak.<span> </span>The mode knob has four different settings.<span> </span>There are also switches for drive and normal boost.<span> </span>A small amount of fiddling with the Q-Tron allowed me to get a pretty good grasp of how to use the pedal and what the pedal is capable of doing.<span> </span>Unless you’re a beginner or are having technical issues, a manual definitely isn’t needed.


<p class="MsoNormal">When talking about the sound quality of the Q-Tron, let me say that I’m usually more of a traditional wah-wah type guy rather than filtering when it comes to guitar pedals, but I absolutely love the Q-Tron.<span> </span>You can really get all sorts of interesting tones from the pedal that will work on everything from funk to rock n roll.<span> </span>I’ve used the pedal for recording, mostly with a Fender Strat and a ’65 Deluxe Reverb, but have also used the pedal with a Fender Jazzmaster and a ’76 Fender Twin Reverb, as well as with mixing and matching them.<span> </span>The sounds that I’m able to achieve with any combination of these is outstanding.<span> </span>So often I find that the Q-Tron could be helpful to my tone, and while I don’t always stick with it for a recording, more often than not I end up loving what I do with it.


For such a versatile and clear sounding envelope filter pedal, the Electro-Harmonix Q-Tron is a great deal.<span> </span>This isn’t to say that the pedal is the cheapest in the world, but it will give you a lot of bang for your buck in terms of high sound quality and reliability.<span> </span>Before using this pedal I never put too much stock in guitar pedals for filtering, but the Q-Tron is real deal and should be tried out by every guitarist interested in cool and interesting effects.

Electro-Harmonix Q-Tron (Original)
This is not an auto-Wha I find it a good old analog envelope filter 100%.
I have a U.S. version in 1980 with the 24v wooden box and all documentation.

For the rest everything was already said.


Pedal a bit touchy but with which one can get sounds incredibly funky.
I have often heard that this pedal was complex to resolve, it was galley ....
At the risk of not making friends, it's super easy to adjust even if there are more than 3 buttons.
The important thing is to tame the blinking LED :-)

For those who do not have the doc is here: https://www.ehx.com/assets/instructions/q-tron.pdf


Is just huge, with a distortion pedal at the output we get to have worked very sound (Maxon OD808) Purchased


hand because I wanted to do casseroles of funky with a nice vintage pedal, I discovered a rich and full pedal.
I tried Auto-Wha and we are very far from what they can offer. The Q-tron is a huge step above.
Can be self-Wha with a Q-tron, but it is that using 2% of these capabilities.
What a difference a Wha-Wha? Bin Q-Tron and it makes WHOUuuuaaAAAAA WHOUuuuaaaAAA MMMHOUuuuaaAAAAA RRRHOUuuuaaaAAARR also

I'm not ready to part with it, and I would do this acquisition without any problem.

Electro-Harmonix Q-Tron (Original)
T says it all
except that the boost button is reversed by RAPORT has the writing on the frame (well on my q tron)

Drive button and also has a bit of play, the "click" is not very strong reassurance that too at life
but otherwise all is well


Personally I jn have had no problem finding a sound that I like
ca m 'a pri 5 minutes to understand that it is barely touching the button "Gain" (the type not to exceed the first 2 graduations) and 10 min walk to see how everything else! (I play bass guitar on the settings are a bit more flexible I think (at overload)


Infact the pedal not work as an auto wah more you attack is stronger the higher the wah WAH
if you attack it bit slowly even have no wah! which is great for feeling!

overdrive after a couple was super nice sounds!

c 'ets FUNKY


I am very happy with my pedal it's been two months that I the planks apart and the little problem finishing at buttons is great! if you are interested j 'ais half my images in the settings I' is most often used

Of auto-wah pedals and filter.
Easy to use, but hard to find SETTING THE crazy: s


The config is simple, but really find it sounds cool hot


Bah I am trsdu. I am the Rasht in 2 days!
I cost the sound of the Mini Q-tron and j'esprer find something as crazy. But no it's really unplayable.


The quality is a shows.
But questions quickly find versatility and sound cool, is dead.

It has 4 pots including one frquences Defines the (low pass, pass b, the medium, and high pass "mix", the report is that me ns contrast are others)

a second will focus on the effect grves or treble

Defines the senibilit a third of the filter, and volume in "boost", and a final which rsonnance Sets the matter of agressivit frquences

we have a line between two output lines, one with and one without the effect, a switch norm / boost, which makes the changes discussed above
and a final sense of quidfinit frquences (of the serious acute del'aigu to severe)
An LED lights up when overloaded sound.

trs all effective, but it is a blow to the rglages as sensitive, not to have his empty sound, easy onse hits overflows frequency drives the eardrum exploding and the speaker.
We regret: the robustness, which nest in appearance of the box, found in other effects of the firm ELECTROHARMONIX.
For me, it's the problems that pop welds, switches of evil fixs damage ...



dj good as said by others rglages are not empty but grope to find, we find the first fin.Le knob to "mix" does wonders, it combines easily with the effect of other sounds. If found to get a cool sound without the LED alarm screams and the sound is not too "resonant," he Relva when even the small challenge.Je did not r Ussita serve me the way "Boost" having a good sound, without overloading.



the effect is standard, and should not ELECTROHARMONIX again to a! The sound is fat, then sexy, bubbling! on the other hand, beware of card volumes! boost the machine Manir sound such that, for my part I must mattres included on the e volume of my bass to get gal volume by turning the gear. impliquede What do these rglages a volume decrease on 'THE intrument.Mais envelope filter is in the dynamic conparaison wha BOSS and of no contest dod ago, she has THE sound.


The Funkateers kneel, the technoman adulation, and others, tonns will!
Really, it's DA sound, be it with a keyboard, guitar or bass. Congratulations!
Well, a little BMOL for the diffrence in size, strong boost when switched on and another for long-term reliability ... it's sold with a wooden box, (well has the 'silent yet there are few), and believe me, it's not for nothing !!!!!

The configuration is a little complicated the challenge is to find his sound ....


HUM, here is the most interresting is really gnial, if you want to give the color, EHJV transistor amplifier, you need the pedals, I can not imagine what his is on a tube amp


Trs good, although slightly rglages complex beginners

Electro-Harmonix Q-Tron (Original)
A large variety of effects ranging from auto wah to the sound of Mu-Tron III.
Works with guitar, bass and keyboard.
CONTRL: gain, range, peak, fashion, south-boost, drive switch.


I note pr hard one, because even if it is the best and easiest to use envelope filter, it is not empty all of the same sounds out of his taste just by turning the knobs fast-fact. You really take your tps and find rglages that correspond to each game.

I tested the envelope filter DOD from home and I could not get a single sound convincing.


The excellent sound st: the sound is pure trs. You can do anything with: from funk to metal through techno.
The effect of the pedals is sensitive trs.


Made in the USA by the designer of the Mu-Tron III envelope filter that is really excellent.
I use this only qd pedals now (song) is appropriate is not the kind of effect should be left enabled all the tps.

The Q-Tron is undoubtedly the best envelope filter on the market.
