The pedal, like the other 4-stomp series pedals from Line 6, is incredibly easy to dial in good (crazy) sounds, while being simple to save patches and recall stored settings. The manual is clear, concise, and with a good dose of humor! The housing seems to be incredibly durable, although the switches...not so much. I haven't had problems with them, but I've read numerous reports of people that have. The knobs provide a good, positive full throw from full on to full off.


I'm rating this a 10 for what it is. Anyone that wants crazy old-school synth sounds or filter sweeps from the guitar should look heavily into this box. It does all the crazy bleeps, bloops, swoops, sweeps, warbles, and just general thick Moog and Oberheim-style synthesizer sounds. I feel that the sounds have really inspired me to come up with some neat, creative parts that I would not have thought of otherwise, and they provide solid hours and hours of enjoyment.


I'm giving this a 9 overall. It's a solid entry from Line 6 into the wacky world of analog synth sounds for guitar. Other pedals have done it, but I'm not so sure any other pedal that does this sort of thing has done it with so much variability, versatility, and general patch sound recall as this pedal has. The brilliant purple coating is a fun touch. One thing - the pedal is much larger than a standard pedal, and heavier, so it adds bulk to a pedalboard setup. This is something to consider, definitely, but the overall vibe of the pedal is pure joy. Highly recommended.

Ultra simple to use, great ergonomics, it is the real plus point.
Everything is in front, a simple and intuitive.
Editing simple.
Moisten fully, it is a treat.
I never had the manual.


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).


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.
