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

Korg PX4D
Everything has already been said, so it is full and complex, I'm not a great connoisseur of digital technology, but the preloaded sounds and rhythms are very friendly and the range of effects is very important.


The manual is not very clear on the record sounds, I've never been able to remember. So the rest, I do not even speak ... Well, I put 5 because I know I'm not stalled at the digital level, looking for a little more maybe I could use it better, but I find it less easy than having to zoom a.


So now, you should know from the outset one thing, it is a device for playing on speakers or with headphones. As soon as you push the sound into an amp, it does not hold up. It is very plastic, the sound is inconsistent. It is not made for that. On low volume speakers or with headphones, it's great, the sound is realistic and there is plenty of fun effects in addition to a variety of rhythms.


This is a very good device in addition to its compact size (can fit in a jacket and hang on to a belt), but be aware that it is for individual use. If you play in the apartment and you can not push the volume, or you travel a lot with your guitar, this little gadget is perfect for you.

Timo_SW's review (This content has been automatically translated from French)" A good travel tool!"

Korg PX4D
It includes several small Pandora PX4D amp simulation / HP, and a bank of effects rather generous for the size and value of the machine.
Simulations & effects are adjustable directly on the machine only, which is not a problem in itself, given the usefulness of the machine.
The input and output connectors are Jack.


The machine itself is simple and intuitive, easy to use.


All sounds is correct with respect to the machine.


I use this little box for 3 years now, when I'm traveling. This is a nice little tool to work when his plans guitar amp is not possible (traveling, backstage ...)

legwenosor's review (This content has been automatically translated from French)" well ... for what I did!"

Korg PX4D
see on the net!


overall it will be going out but I've always had trouble with this type of product ... long live the manual!


I only use it with headphones and pandora with my MP3 player.
in this usage it's going well, in all the sounds go well .... I'm happy for the price .... although the first POD is not more dear and probably better!
the device is compact and travels very well.

it has a looper ... but hey .. I have trouble with!

the only time I used it with an amp .. I found the sounds not that great ...


I've had it 6 months, I use it on the move and I'm happy.

it is small in the suitcase and I play with headphones without bothering people ... there is impecc.
It "eats" the batteries therefore provide rechargeable batteries!!

if used on a multi-effects amp there are probably better and more convenient ..

This is a multi-purpose pocket (it really is in the hand) guitar and bass.
It includes many models (25 + 23 amp speakers) all possible combinations.
Facilities, a number of effects, a drum of 100 patterns, choice of tempo setting or tap with the option to add a bass accompaniment (with tone control for bass, the reverb, its volume ...).
Sampler (30 seconds from a CD player, MP3, MD or instrument), the playback speed can be slowed down without changing the tone and you can change the key of a song read up an octave higher or lower.
Connections: a guitar input, an input to an input power supply (4.5 V), output (to headphones or an amplifier input).


First approach quite intuitive, you plug ... it works, it fiddles with a little ... it works. To go further one must refer to the manual.
The manual is very well done, fortunately, because many functions are not easy to discover. But once we got it the principle is quite affordable.


I would not judge the accuracy of simulations compared to the original, first I did not at all the stuff to compare, and above all I care less!
I find the tone of the guitar and micro well respected, very good record of the dynamic.
(I have no custom shop at home, do you hear the difference between a maple fingerboard and a mahogany? I know and that's not the point)
It is a small tool, not to break the legs around me when I bump the guitar. And here is excellent, plugged into an amp or directly to the headphone listening.
Warning: rendering the headphone is highly dependent on the quality of it, but I was very pleasantly surprised by using it with good headphones. I recommend walkman type headphones because the dynamics of the guitar is great (and it is very well made), what you destroy eardrums permanently into three agreements!
There are a thousand times too many possibilities in my opinion, we chose one or two sounds you love and then stops there.
So yes, good sound quality in the sense that everyone will find a stamp that he likes.


I use it almost daily for four months. It allows me to take my guitar everywhere and work alone. For beginners (and others) is a very useful tool for working in rhythm: I choose a pace that suits me, perhaps the bass (tuned to the key of the song), I choose a guitar sound (amp , effects) and off I went for an hour or two to work ranges, wedge a piece etc ... very cozy and it's much more effective than the guitar in a vacuum.
In addition plugged into an amp does well here (less tiring to the ears as always work with headphones).
Only negative: 30 seconds sample is very short (-1).
It was not like good stuff to the scene but in a room in the car, a tent in the woods ... it's really a great tool which is quite myself.
