I bought my EC-407 last year.
During next 3 month after purchase i changed frets and electronics.
Stock fret work was awful, high e and b strings didn't sound a on 5th, 7th and 16th frets. 1 month after, three-way switch broke down. Bridge position didn't work. After 1 month more, bridge volume capacitor broke down. So a changed both frets and electronic and now works. Nevertheless the guitar itself is comfortable, stock pickups are quite good. There is a little neck diving but not in critical way. It's comfortable to play standing. So the guitar is not bad, it looks cool, it sounds good, but i'd recomend to check it carefully before purchase. And of course, maybe i was a little out of luck, and other EC-407 don't have the problems i mentioned.
