But what changes in a digital spring reverb is not that you switch some analog circuitry for digital. Either you simply attach a DAC to the input and an ADC to the output, but that doesn’t really mean that you get rid of analog circuitry. Or more likely, you’re replacing mechanical parts for a software model that achieves a similar sound. What’s interesting in that is not that you go from analog to digital, but from real mechanical equipment to a software simulation.
