I understand where you’re coming from, but that’s b.s.
My main player is a Fender Roger Waters. I immediately swapped out the pickup because all i cared about was the neck. It’s the only Fender model with that neck.
Before that, my main player was a Lakland Joe Osborn. I had no idea who he was when i bought the bass.
So many people play signature instruments not because of a name but because of the bass.
The Flea sig is a friggin’ nice Jazz bass, and I don’t like Flea.
Same with the Pino Palladino Pbass, but i LOVE his playing.
Judge the bass by its own merits, not by whatever name may or may not be on it.
And trust others to do the same.
End of the day, if a sig gets kids playing, then that’s a good thing.
