Effects (e.g., chorus) that are made for bass generally only process the higher frequencies so that you don't lose the low end during part of every sweep cycle. However, lots of people use standard guitar effects with no problem. If you're into a clean sound (i.e., not distorted metal/thrash), then I agree that your best bet is to spend the money on a nice bass with active EQ, and a nice amp (Eden, Ampeg, etc.) and maybe a sonic maximizer and/or compressor (if your amp doesn't already have one on-board). If you actually want various forms of distortion and funky wah, just buy a Zoom 506 which is really cheap used. It's noisy as heck, but it's not like you'd notice with that music). Honestly, most bassists *rarely* use effects at all -- except for maybe a little chorus (e.g., during a fretless solo), or a little delay and compression (e.g., for harmony while slapping or tapping). But that's it. The Nightbass is awfully expensive for something that you really are unlikely to use as much as you might think. Plus, the non-bass playing members of your band may get pretty annoyed if they feel like the guy who's supposed to be holding down the groove is trying to be a guitar player instead.
