First of all I wish prciser I'll explain the minutes of the pedals with my words. I'll try to put it simply, we know the subtle effects of this kind, so let's be clear. Purists: Do not read this! lol
Classic pedals, a boss, to say nothing solid.

4 knobs: level 1 / Volume.
Tone 1 / Tonalitbr /> Release 1 / trs trs attack rglage end ..
Treshold 1 / This is where everything happens. I explain below.

UTILIZATION

The use requires a certain ear, a certain approach. I had the chance to try it through a friend who bought it at random. She told me more.

Trs trs is subtle in dpart mean the diffrence is hard when the pedals triggers .. one wonders if it really serves.

Ralite and I always wonder if the format is really useful ... PDAL

SOUND QUALITY

PDAL this limit, as the name suggests, the volume has a certain point you set.

She smooths the volume during a arpges (I think a Metallica Nothing Else Matters by exemle ...)

But frankly for guitarise trs is a useless pedals. I said well: Useless! mdrr!

Where they would spend less, it is homestudio.

When (and c'tait my goal) I plugged in and I made a decision to guitar after a while the flanger ... and saw the ame level ever taken!
When I recorded the voice and saw the peaks disappear I thought: "Wow! It's cool!" lol
It becomes a useful trs recording. She saw the peak volume effects or voice easily adjustable ... It makes your decision cleaner ...

OVERALL OPINION

It's a subtle effect trs takes time to adapt and comprhension effect.

It will serve more home studio for the game on amp.

The same effect in it is of good quality and does its job without any problem.
