Whammy and harmony.

UTILIZATION

Very simple.
You just look a little on the possibilities of the "cote" harmony
which are really interesting!
The "rating" whammy "is super simple and intuitive.

SOUND QUALITY

Nothing to say.
That's all good.

OVERALL OPINION

This is an extension of your body, ideal to make your game more expressive.
Essential for the solos, to my taste.
