That is true and for most studio mics (anyone use crystal mics?) it would 
be minimal. Anytime eq is used to bring back low level frequencies, it is 
likely to bring back the noise around that frequency too. Instrument 
pickups are most sensitive to this. I have a classical guitar that I put a 
piezo into. Ok, I broke a piezo buzzer open, put wires on the disk and 
used putty to stick it under the bridge :)   When plugged into my mixer 
(impedance 10k?) it sounded really bad. I could eq it to not bad, but it 
took a lot of eq to do so. My wife has a fishman loudmouth guitar amp made 
for acoustic guitars and plugging into that made it sound wonderful with 
no eq at all. The only thing I found was that phase reverse made a big 
difference in feedback sensitivity... I guess I need to flip the element 
over or reverse the cable.

Certaimly this is an extreme example and while a pickup is nice for 
performing, I normally use a mic for this guitar for recording. The 
point being, that while it is obvious that impedance needs to be 
reasonable to begin with, a lot of people's eyes glaze over with the 
first use of the word. For many people the best thing is a mic with a USB 
plug on it.
