FOR amp guitar or bass:
transistor amplifier that gives the best low-to medium volume but expands what you him entrez.le a better preamp or distortion pedal. I use a jmp-1 or a Boss MT-2, and finally the bass pod xt bass behind me.
The power has the full forli 80W, I used it with a drummer that covered it, phew!
Output on two 12 "integrated.
the connection is simple: two instrument inputs, a single, the other by delivering 24V of a stereo jack. Settings: volume, bass, middle and treble from 0 (nothing) to 10 (full), an inter bass or guitar (not see the difference), and an inter bright / normal (for slamming on acute) very effective . Finally, two knobs for I do not use vibrato that seems to engage with a pedal jack on the front (left)
I would put 8 for clarity and effectiveness of trimmings.

UTILIZATION

The configuration is simple you do not spend ten years to resolve, the sound is a hot medium. I played the police through the bass nightwish and ac / dc and the evanescence or ac / dc see the sixties it does not color the sound too. not too low push it saturates.
August 1 again.

SOUNDS

I play it like I said with a N2 + + JMP1 or EDB605 bass pod Xt. it provides in both but I have not tested may be concert.manque punch on attack as the session "sessionette 75" that I use in bi-amp for bass.
Versatile sound: 10

OVERALL OPINION

I got it 6 years ago an ad for 40 euros.
I play for recreation is good enough for me, if I had to play in club but also probably an outdoor stage, lack of it (I would put both).
unbeatable value for money and yes I would do the guitarist and bassist choice because now I'm happy. a score of seven for max.
