Effectivment, it's tough. And must say it is more beautiful than most other pedals.
2 modes: distortion / overdrive
volume / gain
Acute / low
and ...
Frquence / contour.
Trs complete.

UTILIZATION

The use may take a little time, because the frequencies and the outline fawn really help the sound.

However, it is not a pedals to the metal. It is oriented blues / rock, hard to see. Can be obtained even when its fairly typical mtal by putting the bottom contour, and frquences almost 3 / 4.

SOUND QUALITY

Well, do not Chipotte the quality is good. Fidler Sound is the brand. The distortion provides a sound too "soft," I got too round, and loses much in attack which is a shame. The overdrive allows a much better rceptivit and offers a less muffled sound. However you can rgler with frquence, and contour.
The grain is also enjoyable, just play with the knobs to get the "colors" DSIR.

OVERALL OPINION

Basically I DSIR pedals to make a heavy-mtal, this is not too PDAL This category (I refer you to the MtalMaster Digitech). However I use it with pleasure for the songs rock, blues and old hards time I play more.

Its great advantage RSID in the two small buttons: Frequency / contour.
Too bad we can not push more gain.
