I believe the reason this and many other amps don't come with the gain setting on minimum is because it makes it appear as if the amp has less power. Even though gain and power are unrelated, you can't help perception! I know some speaker amps that have ridiculous gain, where only a third of the volume scale is usable because it gets extremely loud right away. All to make it appear like the amp has unlimited power.
