Well, let's go for the dcrire bte.
Basically it's an octave, it is to say synthtise sound, but not just one octave.
It can multiply the sound of frquence per quarter (two octaves below) up to 8) 4 octaves above), to the fifth and third.
Then we can apply several effects on the GNR many of which take on their full size as an external expression pedal (any operation), such as volume, wah wah, filter and freeze in Note.

The Difference a harmonizer is that you can play chords without problem

UTILIZATION

Trs is complicated to use because we do not know where to start.
For once we do not understand what we did at beginners. But it is easy to options because even without understanding what is happening derrire is fairly intuitive (mostly). Say that having a good time with.

There is an External Casing extension to save the presets. It is on all the buttons are dreglsa every time you put it in the bag, so each time a rergler if we did not like me.

SOUND QUALITY

I use it on guitar and vocals, and as often Electro Harmonix, in addition to being an effect, it adds a whole section in the game crative
The possibilities are standard:
- Playing bass with the guitar
- Playing with the guitar synth (synth sound is truly stunning)
- Add power the guitar, because addition of bass and double notes.
- Freeze function is trs crative

The voice is to comply with laughter, test on all frquences

OVERALL OPINION

I've had eight months.
It's worth it, nothing else like this. Besides, I do not know or is not even on AudioFanzine class, I have to search each time.
I think I'll keep it on the voice, it gives me a kind of alien choir

It's really the kind of effect that I love: it is one thing but the fact that perfection with every imaginable rglages and even more. I love it!
