@JBarz : All three basses compare pretty closely in string spacing, scale, and overall neck feel (to me, that is).
The slight differences I found were:
1. My URB is a 4 string and both of the EUB were/are 5's, so both EUB's width were/are a bit wider to accommodate the extra string.
2. The NS doesn't have a neck heel so I bought one of the NS neck heel "simulators" that NS sells on their website. I actually may instead replace it with something smaller, like a thumbtack but attach it with double stick tape (after I cut off the sharp needle thingy). The NS neck heel tends to get in the way when moving into the higher position, I think something small like a tack would work.
Also, I've never had so many positive comments on the sound and, of course, look of the NS from passersby at my gigs than with any other bass. That's kinda fun (and unusual) for me!
Hope this helps!
