Had a double buck for a while. You can get a great fat tone out of it straight away but if you want somthing more along the lines of a metal tone for id recommend a sans amp or similar. Either that or what I also used to do was record one track with a crap load of mids and some highs, and blend it with a track with low end and a big of growl. Did wonders.
That being said though, ive since moved onto a music man stingray 5 and a sterling 4 string....best basses ive ever recorded with tbh. Pure honest to god workhorses.
