My friends and I share a practice space. A bassist from one of the other bands plays a Dean Edge. He and I are friends, so I pick it up every now and then and play a few songs on it. I have made the following conclusions about it:
It has a naturally "scooped" tone. Not very present in the mid-range, but it has a lot of lows and the highs come out nicely. Great bass (gasp) for metal. The headstocks on Deans are generally large, so you get a theoretically longer string past the nut. This, in my opinion, allows for more "slinky" strings which are easy to bend and less tense. Unfortunately, the pickups can't seem to handle too much digging in and will distort a little but with heavy picking, slapping, etc. Of course, this is preventable. Most of Dean's lower end guitars and basses are made from basswood. If you are unfamiliar with basswood, it doesn't produce as sweet of a tone as mahogany or other woods, but it is very lightweight, so you won't get fatigued on stage. You can do a search on it for more info.
Overall, it's a great bass for the price range.
Hope this helps!
