This is a harmonizer pedals / detuneur: it therefore allows the choice of adding harmonics (l there is a choice between a couple dozen, and each couple was one pedals up, and the other pedals down) or detune the signal, and thus change its rating as one might do with a tremolo bar: High position: note normal low position, note detune (you can go up 'agu 2 and 3 octave octaves more serious)
It's all numrique, and version 4 is controllable by MIDI
Note that we have two outputs, Wet and Dry, and therefore, with A / B Box, one has the simple Manir trs equivalent of a looper to enable / disable several effects at the same time.
Only by the power transformer (12V).
It is all mtal, very heavy, very tough ... it's solid!

UTILIZATION

Super simple and intuitive c'estte PDAL is a rgal use.
Only possibly BMOL must bend down to change the mode manually.

SOUND QUALITY

Used with a guitar, I mainly use the Whammy to descend into the grave. It sounds serious! The pedals used to vary the sound gradually. She remains in a particular position carefree Wha-Wha unlike me who is a bit heavy and tends down alone.
Haroniseur position, the sounds are good too trs.
Absolutely no background noise when the switch activates.
Zro default for the quality of sound.

OVERALL OPINION

I have for almost a year, I love it! it is beautiful, red firefighter is saw on my trs pdalier plutt dark, and above all, it sounds serious and can DLIR as few pedals allow. What happiness!
I have not tried other models is the one I wanted (Radiohead influence ?!?). It may seem a bit pricey, but worth the trs greatly. Well, me and more, I was lucky to find one on eBay for super OCCAZ 150, including postage from the United States, I had that then buy a transformer France / US (10) c'tait and left for a long love affair!
