I would say it has many sounds that are fuzz, saturation and overdrive. Basically it is when even a fuzz pedals and this is the best o it provides.
The PDAL is mtal manufacturing, it is also quite heavy which makes it sound trs, 3 knobs (volume, tone and sustain), switch on / off (a little too hard and quite a turn noisy), an input and an output jack.

UTILIZATION

With 3 knobs, it is faster around the bte and quickly found its own rglages, no need for manual

SOUND QUALITY

I use the big muff on the clean channel of a Laney TF100 (on channel saturated sound becomes too rough and incontrlable)
you can get three tones:
- With the tone knob 1 / 4 and sustain blok, we obtain a saturation trs trs consistent round like "SANTANA"
- With the tone knob a little over 50% and sustain blok, we get a super fuzz vintage of great quality very dirty type "HENDRIX"
- With the sustain knob has half results in a slightly less convincing overdrive I think.

OVERALL OPINION

I use it for 2 years
The +: the quality of its product, the robustness of the pedals
The -: one thing, the switch is too noisy and is hard enough to activate
For 70 euros it is a quality of pedals I advise everyone!
