Harley benton thomann is the brand (read thus they import materials "noname" Asian-brand it), we end up with products whose quality ranges from OK to awful.
Here there is a small 5W amplifier battery with 3 channels (clean / drive / distortion), an EQ on the bass and treble and a headphone output.
Rudimentary but already there are a positive relation to low cost amplifiers: the three channels with a real distortion.
No manual, no use anyway.
The amp is widely copied on the Micro Cube, but also cheap (the plastic coating goes in places).
It can be used on AC or battery, for it is much against the greedy roland amp with 10 AAA batteries, I think it is more interesting to connect.
Ahh the sound, personally I'm always curious to see what we can learn from this kind of low-end amp. Here is clearly a good surprise, the clean channel does not reserve many surprises (cold plate), we go directly to the drive which I believe is almost that of G. Marshall (draft but possibly exploitable to start).
The distortion is more surprising as it rises high enough in the gain (it's almost the High Gain), are not dreaming because the sound is very "niz Bee" but this is enough for a beginner metalheads.
The growth rate applied to the tolerance, the sound is generally pretty bad but for thirty euros (the price of two CDs ...) we are left with a small amp to suit (for example) for breakfast brother who begins by taking the nirvana and co.
Once needs have evolved we can always pass it to another beginner with no regrets.
