Bass transistor 400 watts RMS (8ohms) ...! hard to believe for its size, unless you have a lousy performance ... but it is far from being the case (99 dBspl/W/1m)! So volume and good sound.
1 HP 12 'and a piezo. bass reflex back.
input jack, 1 gain knob, 4 knobs for EQ, 2 pots of frequency envelope (you say it like that?), one master and one master line.
back, located in the output of bass reflex, an XLR DI output, a button to bypass the EQ or not, another for land, two jacks for parallel effects, a tuner output, an output class 2 ( used by default by the speaker), and another speaker output. and the power supply.

UTILIZATION

I have tried with my bass (Ibanez SG500 active) and it never sounded like that, the dynamics are excellent, and the possibilities for incredible sound: marcus miller in new order. So it is to say!
I use it with my band on stage or in rehearsal. I also use it to record DI directly on my sound card (Fireface UC) to benefit from the excellent preamp of the beast.

SOUNDS

As I said, the sound is excellent and completely malleable, round or crystal-clear ... choice.

OVERALL OPINION

It completely worth it. If it again, I will redeem the same.
It is a kind of Swiss Army knife for its size / sound and its ability to report ... but with a katana blade.
