Just a general comment about possibly making decisions based on internet clips (or even internet threads

) ....there are numerous factors that influence the tone that you hear outside of the bass itself- the player, live vs studio, amps vs direct or combo, software, hardware, and the list goes on and on. To make a real direct comparison between any two top- notch basses and their nuances I really think its best trying them in person back to back in real time, and barring that, just playing each of them with your own hands and listening with your own ears- even at different times. For a purchase, I dont think anything replaces doing that ( other than trying them both out at your own gigging or studio enviroments also-which is rare or impossible for most) If you cant play them in person, personally, I wouldent purchase until I could. People hear things differently and characterize them differently and the only thing that counts is how you make those basses sound to your own ears.
I totally agree with Roger's advice to try to make sure you compare apples to apples if you are making direct comparisons too.
