I love the sounds of this plugin! I'm not really knowledgable about how a bass should sound, but it's certainly better than any other bass vst I've used. And it's cheap!
But there's one thing that would lead me to use other vst plugins over this one; the performance isn't all that great. It's fine if I use my own desktop PC because it can handle most things. However, if I use a slightly worse computer, I run into difficulties. The plugin can take some time to load. But while waiting for it to load can be annoying, I don't find this to be a big deal. What makes this plugin almost unusable on some PCs is that my DAW (FL-Studio) stutters a lot (A LOT!) when using Waves Bass Fingers.
Overall I would say this plugin is worth the money but be catious if your pc doesn't have great processing power.
