Well, since the zombie has been resurrected...
A proper loudness control should be linked to the volume control so that it has most effect when the volume is turned down low and has less and less effect as the volume is turned up. It should also be adjustable so you can set it for the sensitivity of your amp and speakers.
On many amps that have a loudness switch it just kicks in a bass boost regardless of the volume - not really right at all.
Btw, some people say that loudness should boost bass and treble, others say it should just boost bass. A look at the Fletcher-Munson curves should show you that only the bass needs to be boosted at low volumes because it's only at the bass end of the spectrum that the curves bunch together at low volumes.
