As much as I love my No. 1 bass, I think you should be just as happy *not* to have a clear No. 1. My No. 1 bass has been my No. 1 since I originally bought it nearly 20 years ago -- a now heavily modded Carvin LB70 with Aero pickups. I've owned many basses during the intervening years, including some multiple times more expensive from some of the big names (Zon, Fender, Gibson, etc.), and have played tons of others, but I simply haven't found anything that can replace the Carvin. To state it simply, the Carvin has sounded great in literally every scenario I have used it, both live and on recording, and does everything I need a four-string fretted bass to do, whereas ever other instrument I've tried is missing at least something that the Carvin has. This means, frankly, that I always have a little bit of fear as to what would happen if disaster struck, as I do not have a lot of confidence that I would be able to find anything that could fully replace the Carvin other than through sheer dumb luck given that it hasn't already happened through 20ish years of trying things out.
Frankly, I was very much hoping that my customized Zon VB-4 would become my new No. 1, or at least reach equal status, primarily because it is so light and comfortable to play, whereas the Carvin is on the heavy side of average with its walnut body and maple neck, but alas it was not to be.
So having an undisputed No. 1 is definitely a blessing, but there is a touch of curse involved as well.
