Transistor amplifier is I think.
It dlivre power 30W, enough for a bedroom or a jam with friends but not a repetition.
There are several inputs: an effects loop, between an active low, between a passive bass, a line out output and a headphone output.
For the settings can not be more simple: volume and EQ low-medium-high frequencies.

UTILIZATION

The setup is really simple trs.
This gives a clean sound (only available initially), it's a good sound.
For the manual I did not have but I think it is not necessary given the limited settings.

SOUNDS

I play metal plutt. For now I just have the original sound of the amp to me enough to play but I think a fact or two will put more dynamics in the game
I play on an Ibanez GSR200 active, we get a nice boost by putting the power.
I like the powerful sound, I have not had the opportunity to test another.
The sound is clean anyway trs beautiful.

OVERALL OPINION

I've had 10 months. I'm happy, I just wide for my room. I think buying some effects when my wallet will allow.
I like the clean sound with clean and clear power.
Qualitprix level is normal and no more, the amp is solid and well made, I have not had to worry until the then it is well worth its 164.
I think I do it again this choice.
