Distortion ..
Nothing else to say .. a power input, an output ..
Alim 9volt or battery ..

A small 2-band equalizer would be welcome .. (like a bass and treble ..)

UTILIZATION

The config is simple .. I have not read the manual .. (no one reads I suposse ..)
The fact that there ale three knob, greatly simplifies the use ca .. (actually a bit too ..)

SOUND QUALITY

Aie Aie Aie ...

It's really not good ... usual, I tended to say "it's not my thing rather than" is not good. "but seriously, it does not .... Ok, the price is really low but you can get Boss DS1 of the net to 45euros and it's really something else ..

It completely lacks prescence is the word .. it is thoroughly cold .. or even cold ...
This is the first negative comment I do but that's too bad ... too synthetic, too cold ..

OVERALL OPINION

But despite this low price a bad value for money .. for that price, there are DOD, the Boss DS1 worth much more the cost.

I am lucky to have a really nice seller who I could see the foot the next day ... (I bought the TS9 that day also .. but, I not compare, it's three times more ..)..
