Loudness boosts bass and treble at lower volume levels (ie flat when loud),
the idea is to match the sensitivity of the ear, but in practice it is just
one more distortion button for salesdroids to push that should be unpushed.

Most likely it is just a ganged pot, look harder, or at a hamfest. Better
skip it.
