A New Way to Capture Tube Behavior
Tube saturation is never static. Its character changes with level, as harmonics build, transients soften and the circuit moves from coloration into compression and drive.
This is where NOVA becomes fundamental, allowing FIRE THE TUBE to reproduce the evolving nonlinear behavior of the original circuit with a natural, continuous response.
The result is a simple processor capable of moving smoothly from subtle coloration to pronounced tube saturation.
Key Features
Continuous tube behavior modeled through Acustica’s NOVA technology.
Harmonic density and compression respond naturally to input level.
A streamlined processor built specifically for fast tube coloration.
How the Two Models Work Together
At the core of FIRE THE TUBE, NOVA combines two complementary modeling approaches to capture both the structural accuracy and the evolving nonlinear behavior of the original circuit.
NOVA does not switch between two different models depending on signal level. Instead, it combines them so that both operate simultaneously.
At lower signal levels, the Volterra component preserves the precise frequency and phase response of the original hardware, ensuring tonal accuracy and stability. As the signal is driven harder, the neural model progressively contributes to the behavior of the circuit, reproducing the richer saturation and complex nonlinearities that emerge in real analog gear.
The result is a system where structural accuracy and expressive saturation coexist - delivering deep harmonic character while maintaining the spectral balance of the original hardware.
