UTILIZATION

Too simple ...

SOUND QUALITY

It depends on the source and output ...
I used it for guitars long. It sounds digital. This is a machine that takes us back in the 80 ... somewhere, happiness .....
The distos can be nice, but in the context remisent I advise all the same external pedals, issue of grain.
Big advantages through connectivity
The reverbs, delays, modulation effects, and filters are certain qualities that are still current.
Machine that blows faster if we increase the levels of output of each module.
The Line filter coupled with the semi parametric provides the ability to finesse a good equalizer.
Some presets gives laughter. : D

OVERALL OPINION

I use it for 10 years.
I'd buy 1000 francs. Rack first guitar. I use it almost for elsewhere, except with very specific sounds. I also sometimes used for voice (like chorus / filter / delay so the Floyd Roger Waters) as voice distortion, with an input 509.
I class in the "Swiss knife" or "it always helps out."
I do not never part! (Na!)

Well, if it really is to the guitar, there's something else much more versatile. It's a matter of taste.
