If we refer to what we may describe as tone controls, there are any 
number of phase characteristics, but the first-order networks associated 
with recording chraceristics have simple and predictable phase shifts. 
As these will have been present in the recording amplifier, it is only 
logical to introduce the correct opposite phase shift by using analogue 
first-order networks or accurate digital implementations of the same 
topology. My point was that not all digtal filters mimic analogue 
networks in terms of phase response.
