SOUND QUALITY

Let us say right away: If you are looking for sounds to Shermann filter, this is not what you need.

Used as part of electronic music on BAR / synth, I find it a good versatile filter, but not quite extreme: it is relatively mild, more than the original that inspired it (see list above in characteristics).

Some effects are extremely interesting to enrich the compositions, or to have filters for versatile mix of electronic music standard (experimentalists and other lovers of extreme sounds, I repeat this is not for you).

OVERALL OPINION

A great effect, which has the same quality workmanship that these two brothers: echo pro and the pro mod but do not have the same reputation, or even who remained in the shadow of the other two.

Not extreme enough for some electronic music, but can be too much for guitarists, it is nevertheless a good filter versatile, intuitive, and very playful.

For over a year I use: excellent value for money / fun.
