300 W into 8 ohms (with the original cabinet)
500 W into 4 ohms (with additional baffle)

In short everything you need to weight and size very small.

UTILIZATION

The settings are very simple.
The EQ is very effective.
The VLE allows for the high frequencies for a more "rock"
The FFT allows one to have two seconds to slap her
The manual (in English) is well done and simple.

SOUNDS

I used a Yamaha TRB (active with large level) and BB5000 (passive pickups Benedetti).
This amp comes out of the grave impressive (especially for size). With the adjustments, you get fast sounds nice for all styles. The only trouble is I think the mediums. They lack definition. And when you want to play hard they tend to be somewhat invasive.
For cons, the "transparency" of the amp is in perspective because even if some colors the sound, it is still typed transistor, it has not the dynamics of a tube amp and still quite cold.

OVERALL OPINION

I used it 4 months in clubs / pubs / rehearsals before selling because the sound did not suit me. He lacked definition and warmth. Also, I never managed to find a sound with a proper balance of mediums.
I was atire by the power / weight ratio in a "reasonable" price. I think it's the highlight of this amp, 20 kg for potato as a body of two 70 kg, all in a package small enough. Its power can play without problem in clubs / pubs with a drummer like a lumberjack.
I also tried the CMD 102P that much less serious and CMD 103P which sounds great but is larger (and more expensive).
In retrospect, I think this amp has great value because it combines good sound, weight and size more than reasonable.
