J am afraid of my planting so refer to the other feedback for the technical
in terms of content was 5 "amp" available to the more neutral "big win"
acoustic, JC clean, black panel, Brit combo, CLASSIC stack and correct.
last for more than one voice
3 controls (tone volume gain) can vary the expression of amps
Two other buttons to access the impact on either one was Phaser, flanger, tremolo and chorus
the other product is a delay or reverb

Finally a generator of 440Hz allows the ear to agree a more accurately
and that's really handy you get used to very quickly tune your guitar without a tuner (after 1 year of use j gives my guitar in just 25 seconds with the LA)
he can walk on battery but I've never tried

UTILIZATION

Very simple config (with the buttons so can not make sense) the manual is useless (except for technical details)

SOUNDS

It is ideally suited to my request
I played it with all for a guitar and I must say that the sound produced was not too bad.
Brit setting combo I like especially (with a slight Phaser mmhh)
against the stack by SET are not convincing, c is true that the large grain volume without it doing it too (I'm already not a big fan in real life ...)

OVERALL OPINION

I've had a year, I bought the aivait to play in my student room. add sound to 9 m2 is sufficient.
I'm really pleased, this is a amp that its price may be great for a beginner.
but it can also be used longer, the sound is not too bad and the "pile on" being practical. the guitarist told there's something to play without disturbing or for travel.
with respect to an entry level amp d c is a bit more expensive but much better ...
