Bass Amp Designer signal flow in MainStage
Bass Amp Designer has a two-channel design—one for the pre-amp and one for the D.I. box. You can use these independently or can blend them by using the controls at the bottom of the window.

Important: The two channels are always used in parallel if the Blend slider is not set to the far right or to the far left position.
The channel signal flow changes when you choose different models from the Cabinet pop-up menu.
