I had a Curbow 5, and a cheaper 5 (forgot the model but it had a MM and a Single coil pickup and only cost a little more than $200 from Dr. Cluck on Ebay). My mixed emotions:
Both basses looked great and seemed rock solid in construction. I really liked the sound of the MM pickup on the one I forgot the name of, but both basses were too noisy for my taste. I'm learning however that I seem to have a problem with noise that others don't mind or ignore. I hate when a bass has any kind of electical hum - and most basses with single coil pickups do that. My curbow hummed also, which is why I ultimately got rid of it, but again - what bothers me is nothing to some.
the other thing that I noticed was consistent with both basses is that bridge didn't go low enough to accomodate the action I like. the neck was buzz free, but I couldn't lower the sadlles anymore. Not quite sure what was up with that. I wound up shimming the neck which worked great, I got super low buzzless action - but it threw off the way the neck sits in the body and my nail would get caught if I was slapping.
String spacing on the cheaper Cort was HUGE, spacing on the Curbow narrow and just to my liking. uhh.... not sure what else. I'd say if yer interested in buying one check it out in a store. If the action and bridge thing is cool, and if the electrical buzz doesn't bother ya none - they're great basses, at a great price. IMO of course.
