• The analog signal path, from the input jack to the speaker(s).
• The digital signal path, which is the path the signal takes inside the digital signal processor.
• A typical Amplifier Model. This simplified block diagram shows the digital signal path through the
many virtual components of the Studio Tweed Amplifier Model. Note that the Fender Deluxe
did not have a Mid or Bass control, so we added these controls post-gain.
