Amp transistor.

30 W.

- What connection?
2 piezo inputs, a headphone input and an input effects loop. A transformer plug and a light load charge.Possibilité the cigarette lighter.

-What are the settings, the effects? ...
Bass, treble, mid, gain, overdrive button level.1.

I put 9 because an XLR mic input would have been welcome, although at this price, it is not asking too much.

UTILIZATION

I want to say you get a good sound ... immédiatement.Le manual is clear, though in anglais.Je limb as the electric guitar through an effects (micro-amp or V BR) of the loop effect on entry or 2.Je Overd never use the amp which is a gadget.

SOUNDS

Pure tones and very good in relation to power.
Curiously rendering seems much better with a mid-range electric guitar with a very high gamme.Peut be do to the fact that a high quality preamp is expressed only with a power amp superior.

OVERALL OPINION

I use it daily for 8 mois.Sa compactness, stability, autonomy, 8 am, make it a plaisant.Meme unloaded, you can use when recharge.Le value for money is unbeatable and if tomorrow this model is in a higher power, I buy it eyes closed.
