Overdrive pedal with germanium transistors (in short, the old metal transistors).
The power is not supplied 9v (hello purchase price if you do not want to put the batteries).
A connector jack input and output.
A true-bypass.
In a safe aluminum (I believe it) It looks very durable. The knobs are also of very good quality.

UTILIZATION

- Configuration: At the beginning it's hard to get used to it. It should tweak.
I explain a knob drive (is it useful to explain its role). A knob and a knob bias volt. The knob used to vary the volt electrical input power to the pedal 3 to 9 volts, it must then set the bias against the voltage. If the setting is done wrong it is very simple it does not get any sound, there are also means to have the old battery of a dream, a nice little effect. The pedal is super versatile, I have not heard the whole I think the sound palette, combined with another pedal or with a few settings on the amp, you get a very wide range. You have to find your sound.
-The manual (in English) does not explain much, it will tweak.

If you want a nice range of sounds I refer you to these videos

Several control concerns (including its clapton)

SOUND QUALITY

Welcome to the 60's-70's rock, there are Clapton, Hendrix, Chuck Berry, ... as mentioned above, there are many many possible settings.
I use my pedal through a spiderII 15w (yes I missed a good vintage crunch on this amp. The crunch channel is rotten, I can finally rock vintage).
The scratching a corte X6 (since it has a simple micro-switch or micro-double can have a good range of sounds with the pedal).
I just love the sound of this pedal, I have tried many OD pedal and it is one that is best for me.
I tested also in a Tiny Terror and it sends.
For metalheads against friends abstain, stay on the MT-2 Metal or muff or otherwise.
The Germanium OD is for the vintage sound.
In its field it is great: D

OVERALL OPINION

I had already tried several times in the store, and yesterday I decided to leave my credit card. If you are looking for a vintage sound try, it is worth seeing.
I love these sounds, I had trouble with the settings but I can assure you after a few hours you can easily find these sounds but I feel however, that the beast did not yet revealed.
I tried several models and it is for me the best in style and has more than a little something of its own.
The quality / price is excellent, apparently the E & H are resistant pedals.
However, you must either use batteries or you can buy a transformer 9v: s which is unusual (I bought a personal transformer at Boss).
