Pitch shifter, harmonizer, boss pedal format, full of possible settings, tremolo arm effect "to take off" (to take off, for those who do not speak the language of albion ...)
"Rsm technology" or "real soundmodeling.réglage dry / wet, detune effect aussi.bref
very nice on paper, walking normally with a 9v battery or AC behringer not included, all for less than 50 euros, or 3 to 4 times less than other ...

UTILIZATION

So it's screwed, to put the battery already is fair game, be supported at the same time on two tabs with a ballpoint pen, to fold a spring, remove the cover and put the 9v battery, and if t ' supports not very strong, you make it and if not you press hard, the springs you jump in the face, like a devil's box ...
Finally you put the battery, new, you replace the cover, reséance of torture, and, and ... the LED does not light when you plug the guitar, the sound does not pass through the pedal, I change battery, jack, I check everything, nothing, nada, not work.
my new pedal behringer US600, I do not therefore "take off", so I will return it to the shop.
otherwise the document is in English, but anyway ...
ps: I of course tried with an adapter / power supply that meets the standards of the pedal
but nothing about the LED does not light when connecting the plug and nothing happens ...
