There are quite a few Rick sample sets, but this one is "Certified" by Rickenbacker. Scarbee libs are always great.
Scarbee himself is a bass player
But as with all sample libs, and virtual instruments, any owner of said instrument is going to say "It doesn't sound like mine"
Yeah, I know, "it'll give you the notes" but there is also quite a few articulations included. As a bass player is it blasphemy to use a sampled bass or virtual bass instrument? I don't think so, it is just another instrument in the musicians hands, use of such instruments can get very musical results in the right context.
