I have found the following justification for the having a bass rolloff
filter in a microphone power supply or preamp:
"The bass rolloff benefit (in this situation) would be to reduct
trafic motor rumble that is often heard inside city located buildings.
Just recording a solo violin would be a situatiion where bass
reduction should have very minor (if any) effect on the overal
instrumental warmth of the recording. Where motor rumble is very
noticable inside, using the 65 cycle position would improve the
recording of just violin by reducing interfering noises."

My question: what are the disadvantages of filtering out unwanted bass
frequencies in post-production? (err, post field recording) I would
prefer to do this in post, because if I filter them out, I won't be
able to play them on my friend's Udder Thump 2000:

Now wouldn't that be a shame?
Seriously, do low frequency sounds somehow introduce noise or other
problems into the recording chain?
Thanks,
