Electro-Harmonix Micro Q-Tron
This is an envelope filter, ie a wah that is Contrle by a shell which they dpendent the same characteristics of the guitarist, wholesale c ' is a wah whose amplitude is Contrle not by foot but with the right hand - or left if you are left handed ...
Well, in short, this is THE sound of funk 70s, used by Stevie Wonder, Curtis Mayfield, Marvin Gaye, Bootsy Collins.
There are three knobs: one Contrle which band opre filter: Low, Medium or Treble. The second call Q Contrle the amplitude of the filter, and the last Drive Contrle attack the sensitivity of the effect.
This is a rdition smaller Mini Q Tron, we can finally add any Pedal Board without taking the place of three pedals, and other suitable Dtail can be feed it with a alime stadard or a garland effect.
You need a screwdriver to accder the battery. It's not great, but not the sea to drink either.


I use it with a guitar. It takes a little fiddling before finding the sound you seek, since it depends a lot of his own game. That said, the three positions are usable. I have a preference for the LP (low pass) after me who offers the most classic sound of the wah wah, and in addition allows galemnt get noisy effects look great. .. effect. Exactly.


Good sound, it's just legendary. Whatever the method adopted was a sound that is a whole section of the amricaine legendary black music. But not only. It can also push the gain and playing chords very violently get Sonic Youth sound on discs such experimentally Jet Set & Trash and Goo.
When using the HP and LP filters, there is a large transparent sound, however, when using the LP filter, there is a boost of volume and audible gain, but we must see that it is as the most effective filter and one that allows for the most punchy sound, and the most funky altrations. But you can not have your cake and eat it too, we must strike a balance between efficiency and noise. Well, it's like trying to save Ann Peebles without the micro saturates !!
In the myth, and despite this BMOL, so it's 10 for the sound quality.


There are effective effects, those who do the job, those who frankly beautiful and on top of that are INSPIRING!
Q-Tron part of this CATEGORY. It is dirty, difficult to master, but buying is like to be an afro if tltransporter Memphis, Stax studios along with Booker T and the MGs and the Bar Kays.
One can also fly away from in noisy worthy of Sonic Youth. From the ct it will leave some imperfections sound, gain it brings to focus only on the warmth and personality of this mythical effect.
It's time to put the funk in your sound - and it's not the music I play. One can just as easily use the effect as an alternative to Cry-Baby to obtain Hendrixiens sounds, we can also learn from Johnny Greenwood and out of the space vehicles sounds Radiohead.
In addition, 80 euro, the quality-price ratio is mortal.

Anonymous 's review (This content has been automatically translated from French)" Q What!"

Electro-Harmonix Micro Q-Tron
Analog effect pedal assembly in the United States (New York City). The Micro Q-Tron is an envelope follower filter. The Micro Q-Tron is a direct descendant of the Mini Q-Tron in a smaller package and with a standard power connector.
1 1/4 jack "input jack and 1 1/4" output.
Powered by 9V battery (6F22) provided, with the added face Mike Matthews above, or external 9V via a 5.5 mm cylindrical negative 2.1 x center connector.
Electric intensity measured by myself: 1.48 mA disabled, 2.12 mA and 2.80 mA in active tip.
1 "True Bypass" switch.
1 knob "Drive" to adjust the sensitivity of the effect.
1 knob "Q" to adjust the bandwidth of the filter.
1 selector LP / BP / HP mode to choose the frequency range.
1 red LED activation.
Printed circuit type CMS (SMDs) (see photo in the "Media" tab).
Aluminum housing with four rubber feet.
1 year warranty.


Very easy to use despite the english manual (see the "Media" tab). Also look in the tab "Tutorials & Tips" for translating the manual into French. After that, just turn the 3 buttons to explore the sonic possibilities offered by this box. I have also chosen for its simplicity, I do not like gas plants.
The knobs are very sensitive, suddenly their adjustment range is enormous: from subtle to wild.
It works by 9V unlike Q-Tron and Q-Tron + who are 24 V.
For those wishing to use it on battery: there's no hatch, need to unscrew the bottom.


His colorful and funky guaranteed! This effect, which is not a wah-wah, is highly susceptible to the attack, multiplying all the sounds. It can be easily combined with other effects (overdrive for example).
I use it with a solid body with two single coil pickups. I did a screen test with an archtop but it leaves Larsen, I would have to deepen my research.
One can also note an increase in volume when the effect is activated.


I use it for a month. I have not tried other, I picked it because of different opinions read by here and there.
What I like most: 9 V operation, ease of use and of course sound.
What I like least: the increase in volume when the effect is activated.
Very good quality / price ratio.

Drive8's review (This content has been automatically translated from French)" Too sensitive?"

Electro-Harmonix Micro Q-Tron
A self-Wah with two settings (Q and Drive) and a rotary switch 3 positions (HP, BP, LP) corresponding to three frénquences wah.


No need for manual: Configuration is simple.


So, for the rendering of the effect: Help, my dear friends: I need your help.
I bought this pedal because I have several EHX I'm very happy.
With this auto-wah, I have a big souçi: I find the correct sound and if unfortunately I hit the 5-way switch on my Strat ... I either have too much or wah I have more!
Clearly, this seems self-wah overreact based on the high / low frequency guitar. So either I rule the Q-Tron and does not change the settings of my guitar throughout the concert, either ... I do not use the Q-Tron.
If someone has a tip to give me, I am more than interested!


I for one year. She made every time a repeat with the group and returned to the box. I can not have a "stable" sound (for the above reasons.

Captain Danny's review (This content has been automatically translated from French)" A flat!"

Electro-Harmonix Micro Q-Tron
Auto Wha analog look nice at EHX.

A IN A OUT, an input power supply, all true bypass.


General configuration very simple:

-A knob to select the frequency range where the effect is (low, mid or treble).

- A knob to adjust the Q.

- A knob "Drive" which adjusts the sensitivity of the pedal, if it is turned frankly it will apply the effect to everything you play, the less shot, it applies the effect only to the notes that you attack the most.

Indeed very simple to use, the manual is just for form and provide the technical ...


The auto-wah effect is very realistic and convincing, the possibilities are many casually with few adjustments rested.

Big caveats:
On a low-, and unfortunately we can not logically use the effect on the high end, which limits the possibilities. On a guitar that sounds great.

-Every time I activais I had a significant volume boost limiting it to use almost exclusively solo, and that, that really limits the range of possibilities and it is zero. Would it have been too hard to add a knob of Volume?


I use a few months, as well use a Wha Wha classic settings and volume Q, the possibilities are broader, more personality, but hey it forces you to play up sometimes over long passages, c ' is the price to pay for better sound ...

The price / quality ratio is still good, as often with EHX.

I prefer the use of conventional Wha, so no, I would do that choice.
