I like their basses. I have an edge 4 amberburst, I think it plays very sweet. nice low action, fast neck, good looks. the emg pickups aren't half bad. only thing I dont like is the basswood body, but at $329 I have zero complaints.
The Edge 4 and 5 basses are a great bass for the beginner/novice. For less than $1000 (sale price) the Edge Improv basses are a steal for a professional quality bass and will rival basses costing much more. I don't dig the Edge 1 at all, not even for a beginner.
