MGR/ShackMan's review"Electro-Harmonix Mini Q-Tron"

Electro-Harmonix Mini Q-Tron
It's a steel, analog, and rather large envelope filter pedal. The knobs are as follows: a 3 way selector between high pass, band pass, and lo pass for the filter, the Q knob to adjust the depth of the effect, and the gain knob to adjust its sensitivity to your attack. It has 1/4' input and output jacks as well as an adapter jack and a battery cavity. I play bass, so I almost always have the unit set to 'lo pass' to accentuate the bass frequencies. It's essentially a larger version of what is now the micro Q-tron. Same knobs. Same features. Just bigger.

I acquired this at the same time I bought the Dunlop 105Q Bass Wah. It cost me about $75 at the time at Pianos 'n' Stuff in Blawnox, PA, but I always try to get my gear on sale. I bought it because I wanted an envelope filter and it sounded fantastic for under $100 for an ANALOG pedal that could stand up to the Moog Murf and Moogerfooger filters in any terms of tone and at over $150 less.

I liken it for a full and bassy tone that is still clear enough to be understood. Even with the wah and the envelope follower, the effects are pointless if the listener can't understand my note. I needed something that was analog (for better signal strength, low noise, and low resistance) and could still keep my notes clear and present even with the effect turned on. This delivered in spades and it was cheap enough to not break my wallet. I like that the knobs represent a very wide range and not a focused sound so that I can go to extremes with my tone if I want to.

The only difference between this and the Moog pedals is the sheer amount of knobs and customizability that you have with the filter's parameters. I find many of the knobs unnecessary for an envelope filter. A bass synthesizer pedal, on the other hand, would be another story entirely, where each slider and knob can have a drastic effect on the sound. Here, Electro-Harmonix has included the only three knobs that really matter:Gain, Q, and Pass Filter switch. Genereally, high pass and band pass are for guitars and keyboards. Lo pass is reserved for basses.

As with many of my pedals, it's steel and solid. I take good care of my equipment, but I don't see this guy breaking any time soon. I've had it for about 8 years now, and I haven't had a single problem. Not even signal noise. Fantastic job by EHX.

The EHX Mini Q-Tron does it job perfectly well, and I couldn't ask for more from the unit. Sure, having the extra knobs could be fun, but I don't see the need for them in this case, so the lack thereof isn't enough to bring the unit down from a 5 in my opinion.

Electro-Harmonix Mini Q-Tron
the +
. sound, warm, clean, Music & Singing
. the 2 settings effective, intuitive, and indeed quite unconventional
. no adjustments unnecessary, it sounds always the quiet, extreme
. Game expression / responsiveness
. supports all types of gains

The -
. More tweaks may be (eg volume) but at bottom the philosophy of the pedal is not to grind 3 weights to find a sound. Anyway for more opportunities there QTron the original.

Electro-Harmonix Mini Q-Tron
This is a autowah that reacts according to the attack, everything is said in the opinions below!


I bought this pedal and used at the beginning it was almost unusable!
It takes effect rgler the inside of the pedal so that it sounds (see the trick to a). Once this is done, we can finally use it correctly (in my case anyway, I do not know if that's all a Q Tron)!
I used it with a bass. Only the LP mode is used, otherwise it has its rglages easily and quickly.


I had bought at departure in the idea of ​​having a sound the Bootsy Collins, because I knew he was using the Mutron, which is a bit of a Mini Q Tron of much better quality. Here it looks vaguely like but it's not really. The sound of this pedal did not really convinced and is not very versatile. Moreover, it is not very effective in severe, like a lot of utiliss effects with bass.


I used a few months and I sold it to buy a manual wah wah, I find really better.
Goodies: she is pretty and sounds correctly even if it's not really the sound I was looking for
Cons: it is not well rgle to departure, is not true bypass, not versatile ...

With experience, I would not have made that choice, I would have rather taken emblem manual wah!

Electro-Harmonix Mini Q-Tron
This effects pedal is an "envelope follower" analog (and not on a autowah we will see why in the "Use")
The connection is simple:
- Between a jack (instrument)
- An output jack (amp)
- A mini-jack for 9V DC
It is also possible to power the pedals with a 9v battery
The case is robust in alumium
It can be used with a bass or a guitar

I put 8 / 10 for some dtails not very practical:
- Need prvoir mini-jack adapter for food
- Requires a Phillips screwdriver your checks the battery
- The pedals is a bit large (all of the same unless the Q-Tron)
- Spurs anti-draping colls did not on my pedals, I had to replace them
- The paint is easily scratched


SETTING THE The effect is very simple:
- A button "Drive" that allows the rgler semsibilit effect
- A button "Q" which enables rgler frquence my pic of the effect
- A 3-position switch that allows you to select the range of the filter frequency drives: low pass, band pass and high pass

There is little buttons rglage but there are all you need. This is what drove me to the mini Q-tron.
Indeed the Doctor-Q is a bit too limited and the Q-Tron is a factory gas.

A manual is provided trs simple but it is nothing, only practice can realize the capabilities of the bte

By playing you realize that the fawn to attack the strings module over the effect the attack is sche and the effect is more radical. (This is not the case with autowah)
That's what makes this trs INTERESTED fawn because your playing, your personality that drives the effect! In fact you play the effect
Rglage with the same stuff on the same two musicians get DIFFERENT DIFFERENT about the results only by their touch.


This effect is extremely effective for sound dicso-funk, electro-funk genre Head Hunters, or metal-funk genre infectious grooves.
The rglages are fine and can really find the sought-its.
It may as well have a discreet ultra Djante an effect.
Overall the sound obtained is not natural is the desired effect.

Personally I use a drive with 2 / 3, a Q 3 / 4 in pass band and gives a far psychdlique ragissant strongly attacks ... is standard
I use a Hohner G3T team of three humbuckers Seymour Duncan Jeff Beck and walk hell.

When you couple the Mini Q-Tron with an overdrive or distortion obtained is your exact psychdlique more ... a real rgal


I use it for 6 months and I love electro-funk sound produced by the Mini Q-Tron.
I prfre is the efficiency of the pedals. This gives very easy on his research with rglages really work ... its really a standard psychdlique
It does not pass the 3 years to learn rgler bte.

What I like least are the few small dtails not very practical as the tabs wrong glue or CHAC battery (see the "CHARACTERISTICS")
These small dtails SPEED her erased by the sounds of rve obtained with the mini Q-Tron.

The report qualitprix is ​​excellent (85 euros)

When I bought j'tais 10,000 miles on his monstrous to imagine that one can get with the pedals!
I have not tried the Q-Tron, but when I hear your exact the Mini Q-Tron ... must be a terrible

I do not often give my opinion but it was necessary for the other ct do not pass this little jewels!

In any case the mini Q-Tron fills me with happiness, I am sound of my dreams

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

Electro-Harmonix Mini Q-Tron
Filter funkifiant (but not only) analog


Super simple 3 large knobs
drive, and Q mode (which lets you play
the bass, treble or bass).
The manual is nothing, we must tinker ...
dlicat is enough, but with a little practice
we find the sound you want ...


Sound quality standard if you like the sound
compress quite a bit aggressive.
I use it on a Start and bass.
Coupled with other effects like phaser,
the sound becomes softer more discreet.
With overdrive is obtained quickly
its saturated the Miles Davis lctrique.
I personally love it with a light ring modulator, which converts
your guitar psych-funk rhodes ....


I use it for 6 months
I like this are standard, like the size less
the pedals ....
I is not trying to further filter before but 60
secondhand pigalle I think the quality price ratio
is unbeatable.
If I had more budget I would take out the q-tron +
In short if you want a versatile filter that requires even when
a little trial and error basis (that of the analog three simple knobs
base, but a rich setting) and you
sounds like vintage .......

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

Electro-Harmonix Mini Q-Tron
Envelope follower (av faults), so for what I know the technique of the effect, and as the doc is a quarter-page résumé is a filter that Ragit function of the input signal with roughly three types: low pass, band and above, rglage the drive (frquence I think) and "Q", say the level of wahwahlike.
so basically, for the jargon, is a autowah;)

old school metal box that looks very tough ...
just for fun, a game comes with strings, it is always nice.
and then the packaging wooden box with lid, it's fun too. but hey, it's not the package that sounds, in short ...


One in, one out, a switch, and battery operation. can not be simpler.


I just beginners guitar, but it seems to me that this is trs pedals well made.
it has a warm, round, a few buttons on the box can be drawn in respect of varied sounds, and it is surprising hip wriggling playing with;)

short, for a autowah, I find that it fulfills its role is all.


Small pedals not CHRE (Thomann) that has a sound that I find impressive.
