Tube preamp and transistor (there are 2 knobs that can be selected and measured).
Amplification transistor.
Delivers up to 350w.
Connector jack input and output for HP.
DI XLR output with built-in.

UTILIZATION

The head is easy to use. The graphic equalizer is useful for finding the sound. The manual is useless.

SOUNDS

I use it with a bass luthier. The sound is pretty good but cold. I still search for a more rock.

OVERALL OPINION

Is my first "big" amp.
I do not regret my purchase, but if it over again, I still save to invest in AMPEG. Good product
