Sound and Circuit Character
The Zener Limiter's circuit uses zener diodes, which are difficult to implement well. Softube says it emulated the full circuit, including transformers, circuit nonlinearities and germanium transistors.
The Input Gain control drives the signal for more or less distortion. The THD toggle disengages the limiter threshold and produces a smooth distortion with a high-frequency bump from the discrete amplifiers and zener limiting circuit.
