Johnny R's review (This content has been automatically translated from French)" Nice "Swiss knife" cheap"

Behringer V-Tone Guitar GDI21
Characteristics? everybody know: it's a cheap copy of the Tech 21 Sansamp GT2.


Very simple configuration, there is no tampering with 50,000 buttons in all directions for a clean sound.
Manual well enough.


The main course we attack: is this sound or not?


Of 27 possible configurations, I do not remember as 9, but all are very good in my opinion.
Let us not forget that we are talking about a device with 26 euros .......

Ultimately, one has 3 switches: one for the type of amp, 1 for the level / type of gain, one for positioning the mic facing the amp ..... it is the latter which m 'left on my hunger, I think, only the "classic" sounds natural position, the other 2 (center & off axis) quickly compress the sound, making all chemical suite, very "low-end transistors" .. ... or very "hyper scooped mids" ...... to play thrash metal of modern hyper death, it may have an interest may be at the limit ..... .....

The switch "ground lift"? I frankly do not know what it is ..... but I have no problem with ground loop, so ......

No "pop" when pressing the foot switch, however the sliding switches can generate sound .....

Another "detail": the gain can be MONSTROUS! I wonder interest to achieve such a level of saturation? knob at 9 am, it's already big guy ..... beyond noon, it gets crazy. And the breath becomes problematic.

In summary, the emulation of amps is relatively realistic "spirit" ..... we recover a Fender, Marshall or Mesa character.

The types of saturations (hot, hi-gain, clean) is a real benefit.
The knobs all have a real impact. Their fault is that they are a bit small.
The foot switch seems a bit fragile. It is clear that this is not the Boss ......

The sounds used (9) are not all bad, after all also depends on what you plug this device ...... I plug it into an AMT TC-3, which is very transparent, and that the nickel ..... I made a complete amp like a shoebox.

We're going a pretty clean clean (missing a reverb), through a nice little crunch to a dito phew ..... sound can really be VERY VERY HEAVY.

The pros:
Prices, sound reproduction, ease of use.

The -:
The blast high gain, the switch "Mic" usefulness questionable, the general lack of strength (but it will if you're not too nags). Maybe mount a real switch in metal stand would be a good mod ..... and cheap too .....

Note that I got better sound by putting a pedal "buffered" before ..... impedance can be a story or whatever .....


Well, finally, a good little device overall, with a Q / P pretty amazing .... I never tested the real GT2, which however looks best on the demos, but the price gap n is really not justified ..... GT2 is still seven times more expensive, but it is far from being 7 times better .....

I tried some multi-effects, I never hung, it always sounded very "cartoonish" ..... and most importantly, what's the point of offering 100, 200 different sounds if ultimately they are people to only 10 good?
There at least, there's no looking 100 take ages to make it sound!

So great machine for a beginner or intermediate who knows nothing distortion and overdrive and do not know what to buy too, nice backup device, or to make various sound experiences ..... and then 26 euros, you risk not much .....

In any case, it makes you want to buy the real GT2 occas' for example .....

I would do without this choice problem.

pdc06's review (This content has been automatically translated from French)" Keep your money for something else"

Behringer V-Tone Guitar GDI21
The PDAL is a Sino-Teutonic CLNE the Tech21 SansAmp. German design, made in China.
And lucky, as I have a genuine SansAmp GT2, I was easily able to compare guitar amp and sound card PC equal.
No need to procrastinate, the GDI 21 pales in comparison with the MODEL.
The Behringer has for her and one XLR ground lift switch as well. Normal output jack, I felt no diffrence so I guess the Gnd Lift is a power supply for the XLR fantme.
Plastic knobs and low end. Internal power supply crap, like most Behringer.


In use, well, it's like his counterpart at Tech21. In fact, I recommend the doc Tlcharger dernire this because it is more complte the examples of sounds than Behringer.
I am not an anti-Behringer but we reconnatre than a dozen pedals of this brand I had (all sold since), I had problem with the quality of 3 / 4 of them is to be dballage in the weeks following their purchase: that spit knobs, switch to lche especially big problem of buzz and breath with a power supply, or even a Maxon Powerplant premium. The power supplies are really bad for Behringer and trs often a problem of mass which makes them unusable.
For comparison, I use more than Maxon branches under the same conditions, and it has great value: high quality sound and no breath.


Having also a Bassman possd two pedals that are supposed to formulate, I can say that none of it well simulates this amp. Even if the grain and tone are not COPIS prs, is the legalization diffrent and warmth of his no.
To speak of the Behringer SPECIFICATIONS from the Tech21, trs is simple: until 1 / 4 of the drive, it is virtually the same.
Between 1 / 4 and 1 / 2, the Tech21 is doing much better in terms of saturation and clarity of sound.
APRS 1 / 2, I do not know, the Behringer breath so as to be unworkable in any fawn.
I prcise I play on Kinman Noiseless Blues pickups, microphones plutt premium and my Start makes no noise part of the channel of an amplifier drive lamps or elsewhere on the SansAmp ...


Keep your dough and buy a real pedals. Your neighbors, your ears and your guitar will thank you. I lost 25 euros, so be it.
Less comprehensive and more expensive, I would advise the AMT Tweed Sound for the Bassman and the Marshall for the M1, or R1 for Mesa. The at least, almost sounds like a real, better than the Tech21 Blonde / British / California and Boss FBM-1 and ST-2 equivalents in any case.

patchylepirate's review (This content has been automatically translated from French)" I'm amazed"

Behringer V-Tone Guitar GDI21
See below, but more than a DI box, it can also serve as simulated amp and distortion pedal


While there, hat! It looks pretty solid (heavier than most Behringer pedals), the button style stomp is pretty big and good.
But the simplicity of use and booklet (English and Chinese) is very clear and lets look at what gives some models.
Attention on a VERY good sound, turn the volume to half, it gives off really.


Personally, I do not like the sound metal, thus, the simulated calif high gain I use it.
on the other hand, with Tweed, clean and classic (all the buttons down) the drive to level 0 and half, I love !!!!!!!!!!!!!!!!! Fender clean sound to it really makes my telecaster and tribute to his neck pickup, restoring its twang.
By adding the Drive, the distortion is very present and the plexiglass is simultaneously really terrible.
I put only 8 because I think the distortion becomes too quick enough there, but it will appeal to metalheads.
I use it since early May (not long) on ​​a mixing desk in repeated more than a concert and DI output, g need to break my head, the engineer did everything in my place volume level. Trankil!


As mentioned earlier, I do not use it for a long time, but I'm amazed.
I did not want to ruin me an amp and a DI box would do the trick.
For 29 € I am very satisfied.
Having already Behriger 2 pedals, I love this brand.
It makes no great noise, looks cheap (and probably is) but I've never had any problems with this brand unlike other large (boss, digitech, Danelectro not to quote them)
Yes, I will ever be happy with this choice.
I have some stage experience and many gear used, one thing to say: do not read these am-called pro who criticize Behringer products that are not expensive, not so good. As in everything, like it or not, then do according to your taste ............ me, I chose

Prampli / Simulator for guitar, between power output and that's it.


Configuration is easy, the simulations are of good quality and the whole provides a wide range of sounds trs if we take time to turn the knobs
The manual is brief but sufficient, it provides some examples of sound, wide average.
Big BMOL, no on / off switch (contact Jack Stereo), I stack two dj grill without too careful.


Effects really work, sounds particulirement crunches are convincing.
Test with multiple guitars more or less good quality, the sound is dlivr tjs trs correct.


ERRF bought my two months ago (he did this test)
MODELS any test I tried the pedals with a friend I found it perfect for use as one can do.
I would do without this choice hsiter if my requirements are the same

Thibault des Walker Texas Bang Bang's review (This content has been automatically translated from French)

Behringer V-Tone Guitar GDI21
40 euros for a modeler analog demende the people?! elsewhere in foto fai i ugly but true evil that the pa tite box (yes usually the DI box are rather manly! refined style koi!)!


Tate Boh is turned a little while Juska kon is the right sound and Wraps (c fast intuitive) (the ti example of the manual are ready to see a little Skon can do!)


Recorded live on my PC, the sound is acceptable super! lol yes fuat not ecstatic either! bah eh lol yes fau not expect to come home a 3 amp madness in 20 cm ² but hey! brief sound gives the ilusion sacred by a record and c galley qu'instalé least the microphone and your amp and devan tou tou that stuff ... c bocou also cheaper!

In short a very good modeler ....
But it was still not the real sound of the amp modeled (normal), but the sound is bonn although we do tell!


Juska, but the AmpliTube 2 is the modeler me most happy!
At the same time AmpliTube 2 runs in 400 euros cete Boie around 40 euros
EDIT of 20 February 2007:
I fell in love with this boiboite, I disconnected my series over effect (c still a good preamp more than anything else how I use it but hey!) Then has the force of using it, I aprris all the pretense and waww!! the fender is magic! waw I really always leaves turn! the brit can do the same on AC DC switch mode preamp BRIT simulated and the type of power stage a "clean" the one is angus young and hot! Angus Young is one of thunderstruck! brief and the mesa we enter the world of punk rock at noon on the gain! we blink voilaa (dsl c lol but exactly the type of distortion on the gain at noon, critic or a fan of blink if c!)


YEAHH! c indispenssable this guitar has all the truk! (Those with less than 10,000 euro budget) do the math ... pk conprenez I mean ... 10,000 euros!
Waww after several weeks of use I find this intenssive boiboite more interresting! waaww! I brought a new dimenssion my amp has this box remains plugged in and turn tojours when I play now!

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

Behringer V-Tone Guitar GDI21
This is a multi FX / direct box
it reminds me strangely of the V-AMP so well frankly
a mesa simulation, a simulation and a simulation fender marshall
with the choice of firms that goes + the type of pickups and finally the mass
but what gun while it's still the price!!


The config could not be simpler, c is truly plug and play with a lot of combination can
no memory in terms of presets or doc but do we really need?


Quality is at the V c-AMP so no complaints
I couple with a boss DD3 valley and a custom art, big sound
the quality is really at the appointment for 40 euros even if I do not use it in the live


I own this pedal since its release, I had bought on the favorite
Level quality / price ratio, there are photos and not one that rivals
Personally, I use the trip coupled with my delay, my guitar and my headphone while ca conscomme by 9v battery, I do not regret this purchase
it would be again, I buy it Dardar

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

Behringer V-Tone Guitar GDI21
The GDI 21 is a success value for money.
I bought that starts with the acoustic version (ADI21) which is a real massacre, a takamine santa fe it is connected as its exellent soaked bass and harmonies.
erant more than happy laa versiosn acoustqiue j bought the 21 I use GDI directly plugged into my mixer and the sound is really hell, I particularly love the sound quality clear style fender


Very easy to use buttons 4 and 3 selectors amp it can regret the absence of memory to recall the settings but that price should not push.
correct sounds are thick and rich in harmonics, and a lot marshall fender super stunning


A Start plugged into this little pedal is extra, if you like bein on the hyper sound filters through 15 pedals it will seem basic, but if like me you like the style guitar amp reverb you will be pleased the size of the amp puique within the pedal returns to cover any scratches


I tois months from the User and I'm happy! * A go for that price

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

Behringer V-Tone Guitar GDI21
Dj said and then there's the site of Behringer ...


I'm used exclusively to play alone or in home studio, never on scne or in groups.
The switch is gnral nothing for me ... What is a power button.
The edition of the sounds is super easy even for big fingers like mine, the knobs are a little LGERS so they look a lot faster ... must be dlicat is not what marshall .

There's actually a ... that fits on an A4 folded in eight.
History of not putting the power supply not included 10 snaps on the ct of the pedals is not very practical forcment ... [edit: and mine "a little grillquot, and all grid transformers that i put, so i use a transformer in the battery case ...]


In total there are 27 possible combinations ... pretty playable and I do not know.

Tweed is an amplifier that saturates around with a lot of bass and treble enough slamming
Brit is an amplifier that saturates most mdium very high and not too low
Calif. is an amplifier that saturates autand that Brit but with more bass, more treble and midrange matris a little hollow.

I think the Brit sharp and not too pretty trs. The caliph and the tweed trs are good (a little tweed crunch means any one of the same ... too wide bandwidth in the high ...)

Cln channel is clean, or at least since with the simulated saturated Brit Calif. and has the big crunch dj.
HiG channel distortion is rich in acute and high mdium
Hot amne more bass and lower than mdium HiG but the diffrence is not super obvious.

Classic: simulates a transplanted by a 57 HP not too low and not many acute
Center: the microphone is located in the center of HP so full of bass and treble
X Off: Microphones off-axis so as center but without the sharp

I only use the center position. Classic makes me think too much and has a softphone qualo offX lack of prsence and do any other diffrence with possde Center.

Point of view of the drive knob lets you go from one to three in winning even if I would have Oens does not hurt to go a little further for distos lacks some sustain and to thickness.
The equalo is quite effective, not like a fender but better than a marshall at least
The level knob does not color the sound ...

For résumé if there are 27 suits me I use only 4 or 5 that I find playable: Calif. / hot / center for large saturated with the substance or drive nice crunch with the drive 0, Twed / clean / center for a clean trs really nice and pretty, twed / hot / center for clean and crunch at the gain which is not bad either. I use the not too gnralement Brit I find worse than the Calif of all the plans a little, as their sound is like.

In any case a sound rather cold and there is no big crunch soft and warm and it is not that bandwidth is a little off in the treble, it is appropriate to a low pass to 12 or 15 kHz to taste one to find their normal HP.


I use intensment for 3 days and I am satisfied with TRS! My distos have more than potatoes in a mix of plugs and I'm forced to turn on the computer for a bit with Scratch sound reasonable!

The sound is not pretty as such but a body which makes them very good guitars Submitted trs and many muscles!

Question qualitprix I think for 46 you can hardly do better ... Ideal for Students home studio just a little broke with neighbors capricious ...

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

Behringer V-Tone Guitar GDI21
All is said, right?
I find it lacks a button to the rgler mdiums. But none of the SansAmp GT2 with a ct ...


The configuration is gnrale I find extremely complex ...
For rglages certainly was 4 buttons and three switches to turn, not rocket science ...
But when you have a sound head, you can spend a while to configure it!
(Tweed Hot with less treble in Classic mode, or Brit Clean off axis mode with at least drive ?...)
The machine makes a wide range of trs sound, despite its apparent simplicity and can be a real s'avrer broken header if it is really demanding.
Personally, I love to break my head in these situations! Then 10 ...
The manual is typical Behringer, useless. And examples are ugly. So -1 for a.


L I do not know what to say.
In fact, used alone, there is a saturation ds, the sound is really, really awful. We speak of "bee" in these cases the I understand why. The way a tweed goes, the other two are audible mode clean - classic mic, but forget the rest. reminds me of a Boss DS-1 plugs into a headset. We can reduce the severity acute salvage, but it's really far from being adequate.
I think they just forget the simu HP ...

However, a simulation with HP (I use the same brand of UltraG), a ring, and really good! It was a sound REALLY warm. Originally I was looking for a clean palette of sounds-Crocks-overdrive to play the blues, and I'm ready! Trs beautiful clean-crunch with the simulation Tweed, the Brit in a clean and overdrive higain gives good color ...
(See forum for examples)
But what do I see, a lamp that heats the indoor? Oh no, this is the diode ... I would almost have thought ...
(J'exagre and I know)

With the simulation of the HP UltraG, I will almost 10. But do not forget I'm supposed to note only the GDI21 ... Alone it is 4. In again.
I mean, come on, 7.


I use it for two days, say that I spent two days on it, and I am far from having made the rounds.
I love the sound, and I dtest sound.
Aesthetics is really good, they chose a beautiful blue.
The report qualitprix is ​​unbeatable, well ... sr
I do it again this election! I bought the APRS BDI21 (the same for bass) because he had convinced me, and the GDI did not either!

But why does it sound so bad yourself ?.... damage, they have something good rat.
If you do not have simu HP hardware or software, where no guitar speaker cabinet to get him out, go your way.
