Abstract
The present invention employs gain compensation such that when the amplifier is in the clean mode, the gain is at a selected level and when the amplifier is in the lead mode gain is decreased. In one embodiment a selectable brightness control is employed to raise the high frequency response in the clean mode. In another embodiment, a selectable gain boost control is employed to increase the gain in the lead mode. At least one frequency selectable means is provided in a post distortion stage output circuit for varying the frequency response of the output in the lead mode.
