it's not. you are correct.

i've been playing and recording bass for many years now so i can't
resist chiming in here...

it depends what you mean. normally "DI into mixer" means
bass -> DI box -> mic preamp on mixer, and this is a very common
way to record bass.

if you mean bass -> mic preamp, that's not usually good.
same for bass -> line-level input, unless the bass is active.
My old Ibanez with active Alembic electronics works fine connected
directly to any line-level input.

i highly doubt it was otherwise identical, but yes, it should 
be noisier :-)
FWIW i prefer large dynamic mics (akg d112, EV RE-20, maybe MD-421)
for micing a bass amp. Large-diaphragm condensers have a treble boost
that I find unflattering on bass guitar. I only tried a small-diaphragm
condenser once and it couldn't handle the low end.
I also prefer micing the bass amp to going DI. The 
speaker -> air -> microphone combination changes the 
frequency response and the attack in ways that I find very nice. 
Mic placement is critical. Mic pointed at the middle of the speaker 
cone is "standard" but not necessarily best for a particular sound.

oh, that :-)
