In that chapter, I will be talking, if nothing else is mentioned, about ideal implementations of the effect in question. An ideal effect is one that is true to the theoretical thing this effect should do (e.g. in the case of a delay, just delay the signal, and not change the frequency response, distort, etc.). As a rule of thumb:
- the implementations in modern environment (effects processors, DAWs,…) that have just the name of the effect or “digital” or “standard” in its name are ideal,
- everything that is treasured old vintage stuff, or a digital implementation “based on” or “vintage” or “tube” is not ideal.
