I have three of the four Native Instruments Scarbee basses: Jay Bass (Fender Jazz Bass), P Bass (Fender Precision Bass), and Rick Bass (Rickenbacker 4003). I love all three.
For my style, I use J bass about most of the time, and the Rick when the bass really needs to cut through. I am using the Precision Bass on my current track because I wanted something that laid in the track better than the Rick but was still more aggressive than a Jazz Bass.
If all I had were the J or P, I could cut almost anything in the rock or country field. The Rick's stereo feature is awesome and there are presets that cover a lot of territory in the rock world. I will be using it on a number of tracks on my new album (which is more neo-Hippie-rock oriented).
The P bass is one Kontakt instrument. Jay Bass comes with a normal and a slap instrument. The Rick comes with a normal and a palm mute instrument.
Note that Craig's Gibson EB5 Bass for Dimension Pro will also handle almost any bass task. It is extremely well-done and available from the Cakewalk store. The only reason I don't use it more is just because I got in the habit (rut) of using the Scarbees and I am very comfortable with Kontakt.
All of these are very reasonably priced.
