The effect is as mentioned below, an overdrive, a transistor analog I believe that 'tube overdrive' appears on the box, connectors, basic, digitech type, a jack input, two outputs, one for amp, the one for a mixing desk, AC adapter jack.

UTILIZATION

Manuel .. Why read it?
Four knob is not very hard to use it ..
Editing sound is more than easy, be careful! has just turned the knob of a millimeter and the sound changes radically, so at first I really did not like it, but now with settings more "research" it is great

SOUND QUALITY

Then voila!
we come finally, the effect is very effective, the pedal does a good job in my pedal board, the overdrive is perfect, it does not take too much to the distortion and it does not blow at all, bypass, perfect, no sound, but if you play clean sound will be slightly colored, a beautiful little grain that I love old school ..
I use this amp on a orange with a triple humbucker epiphone custom AI.

OVERALL OPINION

I use it for two months, I am rather pleased, for the price, the sound is only good if one takes the trouble to spend some time found its settings, I like it very much old school for his side.
The value for money .. digitech it! not bad for its quality not very expensive ..
Oh yes I would do this choice, blindfolded!
