Perfect guitar to play some death and doom metal. It gives a nice low end. On the mids and highs it nicely cuts through. 
On the clean, its a bit thin, I would go for other pickups but in the high gain its very smooth. 
For playability, its my first 7-string but the adjustment to it went very smooth. Its a 7-string, but still has a thin neck (like it more then a fender neck for example). 
For quality: perfect setup, no tuning issues, paint was perfect, nothing I can say that was wrong. 
Have the guitar now for 6 months, never regretted that I bought this one.
