Vintage, Such a device as you propose would have to operate on an already RIAA-equalized signal from the phono section. That's a whole different kettle of fish from applying an alternative equalization curve within the phono stage circuit itself. You'd be better off (less coloration, less noise, etc) just using bass and treble controls on the linestage, IMO.
Chakster, Ralph's post makes a lot of sense. But I was also wondering about the phase issues to which you refer. The very act of equalizing the signal must introduce capacitors, resistors, and, in some phono stages, inductors into the signal path. This will inevitably affect phase, whether the device or the recording is "vintage", or not.
