It's the cheapest version of sg-style guitar, but it sounds really good. Good choice for the first guitar or for home playing.
Firstly, what's bad:
Electronics not shielded, so you will have noise, when not playing. Wire connections made poorly, but works OK. Pickup selector switch is very cheap, mine was broken(only worked in neck and middle position), but Thomann sent me new switch. Potentiometer knobs are good, but looks not very cool, can be easily changed to something more suitable.
Now, good things:
Sound is a lot better, than what you can expect from this price category. Especially when you change the strings. Neck and bridge are already tuned. Guitar is lightweight, but feels solid. Looks great.
