What can be done if my pickup captures extraneous sounds like the noise from the instrument cable sliding across the floor, or touching the surfaces of the instrument?

Date: 26.08.2021

The external sounds you hear are normal, due to the nature of piezoelectrics. The piezoelectric element can pick up any sounds it comes in contact with and is subject to friction, contraction, and any other impact from the environment. 

In some musical genres and styles, these external sounds are a desired effect, such as the tapping on the flamenco guitar, the sound from sliding fingers on the strings. 

To lower the amount of unwanted cable interference, you should limit the movement of the cable. You may run the cable through the strap or tape it to the side of the instrument with paper tape.
You can also change the direction of the cable, so that it doesn't pass through your legs, rub or slide onto them.
