Well all is said:
Simulation 7 Expression Pedal
2 Wahs (and Vox CryBaby)
Digitech Space Station
Digitech Whammy
Univibe
Leslie
Flanger

7 coupled with simulations of distortion pedals (the same as the DF7):
Ibanez TS 9
dod overdrive 250
Boss DS1
ProCo Rat
Boss Metal Zone
Digitech Metal Master
EH Big Muff

UTILIZATION

It would be less severe than the first opinion: the general configuration is simple (four pots with three doubles), but it is true that the edition (the settings) is binding effects just because you have to bend down and turn the knobs. To activate or deactivate the effect you must press the switch "toes" and to operate the distortion effects + you have to press the switch "heel". A second press on the switch "heel" off the distortion and effect.
I recall that it is an expression pedal! and not a distortion pedal! So each is associated with a distortion effect (the pedal is set with a predetermined association with you at liberty to change) and it is theoretically possible to use a distortion only (otherwise you have to turn to DF7). I say in theory because there is a little trick to get just the distortion, and for that you must choose how to effect "Whammy". No matter the setting of the effect, all that matters is set to 0 the output volume of it by turning hard left knob the "Control 3", and even by operating the pedal, no modulation of the pitch will not be heard. Choose your model of distortion, and now operate the.
The manual is very clear, although a bit small and in English, but you can download it in French on the DigiTech website and print it bigger.

SOUND QUALITY

As for sound, most important, it's really great.
Wahs both are very good and fairly close to each other. It must still be careful to find the right setting.
Space station The effect is really fun to use, it allows you to change registry.
The Whammy very well and contains the same settings as the original (except section harmonizer)
The Univibe delivers a good chorus
The Leslie with a bit of distortion makes you to Jon Lord
The Flanger is also very good with quite varied adjustment options.
Disto side I must say again that it's really really good. I had none of the pedals so I could not tell if it's realistic, but in any case the sound is excellent for all models.
The EX7 offers several connection options: either as a traditional stompbox between your guitar and amp, ds is the loop of your multi-effects, or a stereo direct ds mixing desk (and others). Ds it altered the sound is not (but even very good) thanks to the integrated speaker simulation.
Just a quick note, I think the Whammy does not sound great when the distortion is pressed.
For my part I use to supplement my EX7 Vox TSE, and it sounds great.

OVERALL OPINION

I have a little over a month and I'm totally happy.
I like everything, even if I use more often the whammy, the wah and the space station (and distos!).
I have not tried other models because I think it is the only to offer these features.
Good value for money (given what it offers and the amount we should pay to buy 7 expression pedals and pedals distos 7!), € 199 but hey it's still not cheap.
