Tom, I go through basses, it's no secret around here! LOL!!!
But I guess the reason I end up pretty much always back to Sadowsky is you can pretty much expect consistancy in tone, playability and zero worries on the gig with one.
Sorta like my old Fender for me. I always know that I can count on it sounding good. That's why it would go to every gig with me no matter the "bass of the moment". But when I have a Sadowsky, I've taken just one to the gig a lot of times- the Sadowsky.
What I maen by that statement about zero issues is I've owned a TON of what pretty much most here on TB would agree are "top shelf" basses.
Don't get me wrong, they all sounded great and worked on levels that you would expect for basses of their caliber, but at least with a Sadowsky, you have, at least what I have found, is un-matched consistancy pretty much no matter the gig/room.
You can bet your reputation on every gig that you will sound nothing short of good.
A common theme that you can pull from all this is get one on the gig. It just "works".
I can't say that for a lot of high end basses. And again, I;ve tried them all for the most part, and Sadowsky is pretty much the only one that always always fits in any situation very well.
Forget all the talking about SC/HC pick-ups, Ash/maple and Alder/rosewood for a few.
Just toss it all out the door.
We're talking fine points that in the big picture, just diving into a Sadowsky for the first doesn't matter a ton.
It's not like an ash/maple with SC's is gonna sound so massively different from an alder/rosewood with HC's.
Sure, for guys who have/had owned quite a few of them, like myself, Rob & Vic for example, we can really dive into all that, but in the end, it's going to really just have that "Sadowsky Sound" and it will get it done no matter the combo of wood and wires. (unless you're talking Modern to say PJ, then forget everything I just said! LOL!!!

).
You seem like someone who knows a bit about bass so yeah, going in you can pretty much say, and hear the differences in combos we're talking about, but in the end, the result will be the same.
A bass that will always work.
And keep you working.
And I've been saying it for years, and it's evident by all the threads about "XXX Bass vs. Sadowsky" or "why is Sadowsky so good" etc,
NO other bass will ever match the mystique of a Sadowsky.
Kobass pointed out that on the cover of BP Ricky Minor is holding a Sadowsky- I'm pretty sure the three top most widely seen bass players in I would say at LEAST in North America (all three late night talk shows- Letterman, Leno and Conan) would stake their reputations on something that was only going to work "sometimes" or on "certain" things.
