Linear is more sensitive near the top with very little change in apparent volume lower and middle on the fader. That's the math of the curve itself. Log is more gradual. Quadratic even more so and with the change spread out lower on the fader travel. This is somewhat confusing for people in-general already with settings that say Lin, Log, Quad, because if you look at visual curves of the apparent change in sound that, say, Pioneer and A&H (usually) uses, the strait one that you would think is the linear math is actually the quadratic one. The apparent volume change verses the math of the voltage change... a decibel thing.
