Numrique MIDI multi-effects rack 19 "1U
Some publishers are (SoundDiver, G7 ...)
For the rest see the site builder or AF

I put 7 / 10 because the quality of manufacturing is well dea of ​​the reputable brand and concurrency (which foirent knobs, buttons that stand in, bar mount kit trs fragile ...) .
If it is to play the house going, but live or RPET or when must often carry their hardware, we have a good chance of damaging.
I bought mine from OCCAZ 'and I had to disassemble the faade to pick up the buttons that sailed across ...
I find a way knowing that Replifex or Digitech are much more reliable.

UTILIZATION

Config 'complte, relatively simple and easy programing if one has a little experience in this type of machine.
I saw those who slows because you can not rgler scne quickly and easily: it is not for normal, normally the presets the facts before we move! If you want something that is easily and quickly RULES we take a SERIES of pedals and a roll ...
The manual is well done and enjoyable, it tells much about the function of each parameter.
With a little practice in the world of multi-effects program is easily and quickly (personal, I program through G7 Editor and will rev quickly!)

For the config 'MIDI I do not comment given that I only use program changes, but many paramtres be modified by Change Control.

8 / 10 because they could amliorer ergonomics and reliability with a preamp and TC insert gnial t have to use some effect before the distortion (eg autowah and comp.)

SOUND QUALITY

I heard that the G-Major puffed signal ...
It is not wrong but using it in an effects loop in parallle you always dry not affect the signal.

There's then the eating and drinking in the effects!
Compression and trs autowah are good but as they are placed on APRS pramp, they serve no bah!
The flanger, phaser and tremolo (a serving is what to do?) Are nazes (the phaser is laughable even when) but I do not care what are the effects that I do not!
The chorus is nice and well ditables, I like their grain trs California studio of early 90's even if I prfre pais chorus well my GP-8.
The delays, pitch / detune and reverbs are really Russian and Fully parameter. By focusing well on all rglages one can draw some great effects. All times are subdivisions of the (round, white, black, eighth and sixteenth note + all dernires into wedges and triplets) and sandstone are the Tap Tempo, which is very well done also (by the rear switch or control change MIDI pdalier a stroke).
I use it mainly for its delays and reverbs in my derrire SERIES JMP-1 and I did not notice a so-called loss of signal or altration ...

I put 6 / 10 for the quality of reverbs and dlais but phaser / flanger too means and can not properly use autowah and compressor ...

OVERALL OPINION

I for 1 month. Before I had a Digitech S100, a TC M300, a Intellifex a Replifex and only the G-Major rpond my expectations. Just the delay (effect on which I require trs) gives me everything I need.
A OCCAZ of 300 'and 400 new, the report qualitprix is ​​excellent.
I obviously do it again the same choice knowing that I test and dj DGIG many its competitors ...

7 / 10 in gnral because of the quality manufacturing and leaving DSIR FCHE a bit, especially coming from a brand like TC Electronic.
