Looks really amazing. Sound is clear and bright with very detailed mids and somewhat scooped lows. I found it great for practice, where all nuances and mistakes are visible.
I can't say the tremolo is good, after few divebombs it went out of tune, but maybe I would get used to it and find the way to use it without going out of tune... But in general I did not see much difference between this Edge-Zero II and cheap FRS that I have on my other guitar. Actually my old FRS stays in tune better, or it's me being accustomed to using it in a way that it stays in tune.
The reason why I sent it back is poor quality, particularly of the fretboard. It looks like the frets were cut very inaccurately, so when they were installed the edges were so uneven that it could not be fixed by the filing. Nevertheless, it did not stop the unknown "master", so he kept going and cut through the fretboard leaving ugly ditches next to the most uneven frets. One can ignore such a minor flaws if it would do the job and the frets were smooth, but not at all! In fact they were still scratching my hand, so after practicing one arpegio on 10-12th frets for about one hour, unpleasant scratchy feeling in my hand has become so intense that I decided to return the guitar.
I have never seen such a poor finish before. Although all my previous guitars costed below 200 Euro, none of them had received such a fretboard treatment. And of course I was not expecting it from a guitar more than 2x more expensive.
However, sound and look-wise it is beautiful and now, when I don't have it anymore, I'm thinking that maybe these fretboard trenches are not so bad and one could get rid of the scratchy feeling by more filing of the edges... After all, the look and sound are really nice!
