It's all transistor.
I use it with a violin, the power is barely enough to cover the battery, but the possibility to resume output jack on the table.
Reverb on it quite useful for the violin. Otherwise it is because of the classic.

UTILIZATION

Trs simple configuration. (No need to read the manual to understand.) Is obtained quickly trs sound DSIR (I remember that I played with a violin and so I do not know if any applies to other instruments.)

SOUNDS

I play in a rock band (it can cost a sound that overlooks http://magenstria.free.fr ) and appropriate.
I play with a Yamaha electric violin and the effect that the rverbe I use the amp and that is enough.
One small problem, but not least, high volume (because I have to cover even when the battery) the amp blows normment.

OVERALL OPINION

Despite this problem of breath, the report qualitprix seems good. However, if I make another choice I do not know if I would opt for this because this inconvnient MODEL is heavy, especially for a record (eg TV set or radio)

My rating is pluttsvre compared to usual notations of the site but I remain objective prfre
