A large variety of effects ranging from auto wah to the sound of Mu-Tron III.
Works with guitar, bass and keyboard.
CONTRL: gain, range, peak, fashion, south-boost, drive switch.

UTILIZATION

I note pr hard one, because even if it is the best and easiest to use envelope filter, it is not empty all of the same sounds out of his taste just by turning the knobs fast-fact. You really take your tps and find rglages that correspond to each game.

I tested the envelope filter DOD from home and I could not get a single sound convincing.

SOUND QUALITY

The excellent sound st: the sound is pure trs. You can do anything with: from funk to metal through techno.
The effect of the pedals is sensitive trs.

OVERALL OPINION

Made in the USA by the designer of the Mu-Tron III envelope filter that is really excellent.
I use this only qd pedals now (song) is appropriate is not the kind of effect should be left enabled all the tps.

The Q-Tron is undoubtedly the best envelope filter on the market.
