Greg,
I've owned both a V63 and the CS for years and have compared them side by side many times.
I still have the CS.
I had both guitars setup by the same lutiher, same Rotosound Swingbass 45-105 Strings, as close to the same action as two guitars could get, same USA Hartke Amp, same cable, and NUMEROUS other (more talented and experienced than I) musicians present on many different occasions.
My V63 was a 1988, with a very slim neck, and my CS is a 1995 with a very comfy neck, but not as thin as the V63.. I actually bought the V63 to retire the CS thinking it would be virtually the same guitar.
In my case, they were two totally TONALLY different basses. I KNOW they were basically both V63's, but there was a very noticeable difference in the tone.
I always attributed it to wood grain, age of the wood, different model years, anything I could think of, even the Vermilion neck & ears. Even when someone else plays my CS, I'm blown away by its PIANO like tone, hence it isn't just my playing style, the bass has that sound, it is just the basses voice. Clear as a bell and sustains forever. Piano like is the best way for me to describe it.
The V63 was a fantastic bass in its own right, but it had a much more aggressive or ballsy tone if you will, it had THE GRIND. I played it for YEARS and always loved the FEEL of the bass. Its was more comfy to play then the CS because I love thin necks, but the CS had tone superiority IMHO. I eventually let the V63 go BECAUSE it wasn't enough like my CS in tone and the single coil noise for some reason was horrible in the V63. So much so, even after having it shielded, the sound guys would kill the volume and highs trying to muffle the 60 cycle hum. I just preferred the CS in the long run.
Now, I'm not a technical guy, I just play. I couldn't tell you WHY there was a difference if my life depended on it. But also having had the opinion of quite a number of other musicians, some on this forum who have made the same observation, I'm pretty comfortable in my humble opinion.
"That's my story and I'm stickin' to it."
