All told adj t (see the opinion of McRedneck fairly complete)
Résumé to (well, I'll try not to repeat everything said t!)
7 bass effects pedals on clbres or modulation of expression
+ 7 modlisations overdrive or distortion
+ Volume pedals
If you want to listen and give you an ide of what a given ...

Can be used only distos (cutting effect, the trick has given t) and each disto raffecter the desired effect. In other words, one can use an expression with the effect of any distortion of MODEL (see manual) even if they are not coupled to departure.

UTILIZATION

It's just the weak point of the pedals ...
Let's say the PDAL has the default of its quality! As it offers many possibilities, we quickly want to save presets in memory, which is not possible.
Each knob is not the same function as the MODEL of effect: for example, a knob will do such an effect on the volume and tonality will be the effect on another. ancessite well know what fiddles! Fortunately, the manual is well done and Franais plutt useful ...

But hey, you get used to quickly use trs. The use is pretty easy and then relativize somewhat as "default" of the pedals do not have very heavy front psent its quality!
Besides, I have no problem live. Just bend down a bit before 5 seconds ... a will ... But those who would use several of these effects in one piece, with DIFFERENT paramtrages may need to be opt for another type of format pedals (with memory) ...

SOUND QUALITY

So we fall in the strength of the pedals I think.
I am not at all a fan of modlisation and multi-effects (but I have nothing against either), yet I won t this pedals.
I was looking for some effects (wah, volume, flanger) but a little m'embtait sparment buy, cheap, only to use it soon.
L I can say that each effect is very well, sounds great and offers raliste possibilities. The rglages are not caricatures, you can use any and all paramtrer and sounds great every time (well, the extreme rglages will perhaps be too much .. but it's like has with all the pedals right?!

Finally, what I bluff is the quality of distos. C'tait gadget for me and I had no intention of using it to beginners ... Nevertheless (I possde dj 2 of distos intgres and I know some others), I must admit that modlisations are pluttrussies. I continue prfrer Obviously the real pedals and I do not think you can easily juggle distos live but offers opportunities nice (dj can avoid a to juggle multiple pedals at the same time!)

OVERALL OPINION

I use it for several weeks.
The pedals seem strong.
I am totally satisfied. All effects are INTERESTED and usable, and for live recording. The object is not given but is worth its price without a problem because Digitech truly Russian a shot.
Given all the possibilities it offers, I am not prs to have gone around and get tired (especially since I do not know well or manipulate the Whammy wah Ca ... come ..) but I know that, even discrtement, the pedals will enrich my next shot sr compos ...
In short, a great tool.
