This guitar is great for beginners and experienced guitarists though for different reasons.
Oddly I don’t think it’s suited for the middle ground, eg as a second guitar when you are committed for the foreseeable future.
For beginners it’s a great set of all-round features to get you started. There MIGHT be some issues with fret ends and set up that might impact playing, but these are not of great concern (both because of infrequency and because of the safety net of Thomann’s returns service). It also works as a great modding platform, when you’ve outgrown the pickups, bridge, tuners you name it.
This is consequently what makes it great for advanced guitarists. Someone of experience, who is comfortable modding it DIY, who can manage some basic setup steps to tune it to their liking. Can find a solid foundation to build upon.
As someone who is still early in their exploration of the electric guitar, who wants an instrument to love for the core years where they’ll likely develop a style, write songs and gig etc, you might not have the experience, skill or frankly interest in doing what a luthier should be paid to do - you go buy a more expensive instrument that’s ready to rock out of the box.
