2 pedals boost in a box, simple connectivity, ie input / output, powered by 9v battery or mains transformer. Pointers are illuminated in blue tone when the channel is activated.

UTILIZATION

The presentation is very simple and intuitive: volume control and a three-band EQ per channel. I unfortunately bought used without a manual.

SOUND QUALITY

As for sound, this pedal is fully transparent with a minimum volume and tone knobs to noon, there is no difference between the bypass and On. I use a stack to boost Orange Rockerverb 50 is very good and can cover a good range of sounds. Only small downside, even with the boost to the bottom boundary is sometimes go to tease the big win that spot ... It is a shame not to combine the 2 channels. I pair with a T-Rex Overdrive and Michael Angelo's great.

OVERALL OPINION

I use it for 5 months, this is my first boost per se, I was pretty adept overdrive. This is certainly an expensive pedal, but given the quality of construction (housing indestructible), sounds and the convenience of the 2 channels, it's worth.
Finally, a video I made when acquired:
