As the “only thing”, that’s a pretty big thing. And what people have been saying.
Summary of the article: Passive instrument tone is absolutely changed by different cables. The effect appears to be related to cable capacitance.
One can infer that piezo basses are even more susceptible than those tested.
So I’m wondering: which manufacturers advertise low impedance?
