There are four linear knobs: speed, range and width 2, and the mid knob and a selector of effect: are the flanger of "small" to "long".

UTILIZATION

Pedal to metal, very resistant, it quickly found its sound by playing with the knobs.

SOUND QUALITY

AMAZING, I recommend to fans of RATM search, (it is no longer manufactured and it is very hard to find today and one more France) RATM sound is there; pedal Apart from these numerous setting allows us, again, to look for experimental sounds interesting.
Just one less by what it blows a little.

Anyway, the "flanging".

OVERALL OPINION

Musician friends, if you buy it OCCAZ do not miss out, for my part I bought a small fortune on the net, and does not part with it.
