UTILIZATION

The configuration is very complete. It is in the form of algorithm, to explore every possibility imaginable ... (I think I read that The Edge (U2) used this rack on the album Zooropa). In fact you can browse the pages diffrent SETTINGS using cursor easily accessible.
The manual is complete.
There are 105 preset and 105 user, leaving room for the wildest Creations ...

SOUND QUALITY

The highlights are undoubtedly the reverb (including the famous DigiTech Gigaverb), the delay are powerful enough, the chorus is warm, the phaser is nice.
In short the whole is very very good, and is netement best that I could try to boss ...
It is in fact (without distos) of the main effects found in models "DSP Artist/2120".

Note that the effects rack is of course destined to guitars, but it also includes modules adaptable to keyboards, bass, vocals, drums etc..

OVERALL OPINION

Excellent quality price.
