I've played this guitar for a bit more than 2 months now, and bear in mind that I'm just a beginner, that is my first guitar.
So far I've only played classic and hard rock (i.e. Creedence Clearwater Revival and AC/DC) using my Blackstar Fly 3 mini amp (great beginner combo btw). I don't use much gain though. Distorted, this guitar sounds suprisingly good for this price. Not very muddy and pretty heavy. The pickups are cheap, but they sound quite good, for beginner's level you cannot really get any better.
To my surprise, this guitar's clean sound was excellent: bright and quite warm.
About the negatives: the guitar is pretty heavy. Playing for a longer while when standing can get pretty tiring I imagine.
The biggest flaw is by far the string action. It's set pretty low by Thomann and from frets 2-8, mine was so low I got fret buzz with almost every note. I know it's not a big deal, but beginners like me don't know how to adjust the action right away.
Another setback is the neck's thickness. It's a bit too thick. If you have smaller hands, this could be a big problem for you.
Everything else is pretty much a standard on this guitar. Since it's my first one, I can really compare, but the frets seem nice with smooth ends, the binding is on point, the knobs feel okay and there weren't any cuts or other cosmetical errors.
Overall, I couldn't ask for a better guitar at this price point. Great for a beginner who is aiming to play some heavier-style music, but also excellent for blues. With an adequate amp, this is a terrific starter guitar, especially if you can sort out the string action.
