Well the config is obvious I'm not going to redescribe.
Only thing I like is being able to control another device with MIDI (but I make hacks capilotractés).

UTILIZATION

Its super intuitive, so no need to know thoroughly the instructions on it.
Everything is very accessible thanks to the wheel and associated sliders.
For usability I see nothing to say it is very good.

SOUND QUALITY

The effects are quite good although a little less than a crystalline TC Electronic.
But it is well made I trouve.Le preamp is also remaining fairly bon.Ca modeling but Bossant well above one arrives to obtain super resultats.Je used before entering into a JCM Slash and j ' Grab a Mega distortion but also dynamic crunch and deep cleans.
I love all the sounds I get out (but again the model is forward)

OVERALL OPINION

I board the multi-effects since it came out (or so) and keep in spite of my new material "pro".
There's everything you need to correct budget.
The only problem there is a guitarist qd-effects is that all effects are in the same block, therefore, impossible to cumulate and phaser whammy for example.
I'm glad I bought this and the multi recommend for a person seeking a compact (not rack, lol) pretty versatile.
