Usually is, but, no, not always!
I recently bought my second Ibanez Mikro bass, one of the GSRM20B models in weathered black and with mahogany body from 2017, I switched the EMG Geezer butler P pickup I had in my old black Mikro, a 2010 GSRM20 with basswood body I have modded fairly heavily visually, over to it, but couldn't fit the Geezer Butler J pickup in it cause the cavity for it was routed too short, so left the stock one in.
Well, fast forward, it didn't feel quite right in my hands playing it, and although it acoustically seemed to have a more present and open sound, the amplified tone lacked something too compared to my old Mikro, so I quickly switched back to using my old one, putting the Geezer Butler P pickup back in it.
Further more the new Mikro turned out to have a slight buzz on the high G string almost consistently over the entire fret board and the neck wood seemed to be of worse quality than that of my old one.
If those issues hadn't been there it might or might not have turned out my new favorite, I do really like how my old Mikro plays, feels and sounds though, so probably hard to find a bass that would be able to replace it.
My good old trusted black Mikro, which is a bit beaten up, since I tried, but failed, drilling an extra far neck pickup cavity into the body, which I then had to fill up with filler mass and paint and varnish it over, and in the process also chipped off a bit of the fret board, concerning the last two upper frets of the low E string, which I then glued on again with super glue (luckily plays and sounds like it used to before my haphazardly performed procedure):
