Hi John and list,

Sounds like a response one would get by simultaneously turning the bass 
down, and the treble up.
It could be implemented as simple as using a classic tone control 
circuit with a dual ganged pot. One gang for the bass, one for the 
treble, wired so that turning the pot turns the bass down and the treble 
up or vise-versa.
