Tube Saturation and Circuit Modeling
FT1-EMU uses a quad tube engine with two E83CC tubes for bold saturation and two 12AT7 tubes for smoother harmonic warmth. Freqport describes the model as refined using measurements of the hardware unit and optimized for real-time performance.
The component-level approach aims to keep the nonlinear behavior and dynamic response of the original circuit, which matters most on material where saturation changes with input level.
