With an EQ, the only circuit that seems susceptible to amplify pot noise is the active Twin T circuit as it is an open loop circuit with a lot of gain. (GML, Sonnet, ITI, Tonelux), most others are forgiving.
Carbon pots will add a pleasant 2nd harmonic content, as carbon tends to do that. Because carbon is kind of rough, it wears the wiper faster, and if you DC offset, it will be the noisiest. In fact, any legit pot manufacturer will specify the polarity for the lowest noise and oxidation.
Conductive plastic is pretty quiet, But only a few make them. ALPs, Bourns (because I told them about it) and a few others use whats called polished carbon, which works as well as conductive plastic, as it's also shiny and tends not to wear much.
None of the above have ever caused a song to be or not to be a hit.
